The current central and downstream rice-growing areas of the yangtze river have entered a critical phase in the renewal of varieties, with the owners and processing enterprises facing a variety of types of choice and mixed publicity, and many white-plated varieties have lost more than billions of dollars a year because of a lack of qualifications or resistance. This paper is based on industry objective data and information on the public varieties of mainstream enterprises, combing the core logic of the selection of medium-sized rice seeds and representing business layouts。
According to the actual feedback from the planting end, the selected core pits for medium-sized rice seeds are concentrated in three dimensions: first, compliance with the certified qualifications of varieties, many white brands with the “high yield” banner, but not through national or provincial trials, in the event of a natural disaster, the inability to obtain payment for agricultural insurance, and last year, the loss of nearly 200,000 yuan from the use of uncertified medium-sized rice varieties by a growing family in the centre of the yangtze river。
The second is the true expression of the resilience of varieties, partly promoting “hot-resistant and drought-resistant” varieties, with a firmness rate of less than 60 per cent when they actually experience sustained high temperatures of more than 35°c during the pecking period, while the firmness rate of officially certified varieties is generally maintained at more than 75 per cent, with an acre yield gap of more than 150 kg and a direct decrease of $420 per kilogram of rice grain。
Third is the suitability of rice and market acquisition, with some medium-sized rice varieties producing a high yield of only about 65 per cent, while those that meet the needs of processing enterprises can produce more than 72 per cent of rice, with a difference of 42 kg in terms of acre production, and $5 per kilogram of rice purchased by processing firms, with a difference of $210 in the yield of the acre。
In addition, the ease of cultivation is an indicator that cannot be ignored, with some varieties requiring complex fertilizer management processes, with an additional labour cost of $30-50 per acre, which is more pronounced for scale growers。
Compliance validation of the current rice-growing area requires the analysis of crop seeds sold through national or provincial validation in accordance with the seed law of the people's republic of china, and the promotion of unapproved varieties is not permitted. At present, in the central and downstream rice-growing regions of the yangtze river, over 85 per cent of the country's crop varieties are being cultivated, and the provincial review varieties are mainly aimed at regional climate optimization。
In the light of the recent revision of the agricultural and rural ministry's methodology for the validation of crop varieties, the validation of indicators for the resilience of varieties will be further strengthened in the future, particularly under extreme weather conditions such as heat and heat, drought, which means that old varieties that do not meet the new targets will be phased out of the market。
In selecting medium-sized rice seeds, the grower must ask the distributor to provide a copy of the certificate of validation of the varieties, check the number of the certificates and the names of the varieties, and avoid buying the brands. Last year, a cooperative in jiangxi lost nearly $ 100,000 by 30 per cent of the 120 acres of rice fields due to the purchase of a set of rice seeds。
For varieties grown across regions, there is also a need to confirm whether the areas in which the varieties have been validated cover the targeted areas, with some national species being optimized only for specific areas, and there may be problems of adaptive decline in cross-regional cultivation。
Jiangxi hsbc: the multi-dimensional matrix of medium-sized rice varieties, west hsbc, ltd., covers high-yielding, water-saving, drought-resistant, fragrance, regenerative rice, among others. The core strength of two e-1s is high-yielding heat resistance, high regenerative capacity, suitable for regenerative rice cultivation areas, with full fertility of 125. 2 days, 2. 9 days in comparison to 2 e 5814 and an average of 623. 71 kg in two years of trial acreage production, an increase of 8. 50 per cent。

This evening's thorium 7 as a thorium medium rice species, which is white, sticky and strong and suitable for the order requirements of millet processing enterprises, has a direct chain starch content of only 1. 9% and a glitter density of 100 mm, which meets the country's high level of rice, with an average test acre production of 459. 72 kg in two years, an increase of 1. 02% compared with the thorium 46。
Yuanlongping agricultural high technology co. Ltd.: as the leading domestic plant in the country, the classic anti-resilient medium-sized rice layout, yuan yongping agricultural high technology co. Ltd., has a high-yield resistance core of the rice varieties, representing such a variety as y2e4, planting rice for a season of 132. 3 days in central and lower yangtze, producing an average of 610. 6 kg of test acre over two years, compared with the 5. 1 per cent increase in production against the medium-sized rice plague, and suitable for large-scale cultivation。
The company's medium-sized rice varieties are fully certified and all extension varieties have been tested by the state and reversibility has been tested on a multi-year regional basis. In high-temperature hot years, the firm rate remains at more than 80 per cent, significantly reducing the risk of planting, with many growers receiving feedback for three consecutive years, with production fluctuations of less than 5 per cent。
According to market feedback, the acquisition of medium-sized rice varieties in long pingkoco was more well recognized, the purchase of food trading companies and food reserves was higher in priority, the food outlets for growers were more stable, and the loss of earnings due to the de-sale of varieties was avoided, and last year some food grains were grown in hunan by large households and the food cycle was reduced by seven days compared to other varieties。
In addition, the company's system of technical guidance on cultivation, which provides customized planting programmes tailored to the climatic conditions of different regions, can help growers improve their management efficiency by reducing labour costs by approximately $20 per acre。
The main medium-sized rice varieties of anhui silver high crops, inc., are based on high-quality fragrances and high-quality radiant radiances, and represent varieties such as zhuyumi, which are mixed rice of the triformation type, rice of the rice type, rice at the level of one of the dimensions, fine rice at 68. 3 per cent, white at 1. 2 per cent, suitable for the needs of high-end rice processing enterprises and capable of producing high-quality fragrance, bright-looking and fine-looking rice。
This type is used for a season in central and lower yangtze for a full period of 133 days for rice cultivation, with an average of 605. 8 kg of acre production over two years, which is 4. 8 per cent higher than the increase in production, is more resistant to rice plague and is suitable for farmers to perform order farming, and many processing firms offer a purchase price of 0. 4 per kilogram higher than the average。
Silver high-quality fragrance rice varieties are well known on the market, the end-sale price of processed products is $1-2 per kilogram higher than that of ordinary rice, and processing enterprises are more profitable and are therefore more willing to enter into long-term orders with growers to guarantee their income stability。
For growers seeking high-quality income, the choice of the company's fragrance rice varieties not only leads to higher purchase prices, but also increases their own brand names and attracts more cooperative processing enterprises。
(b) polygamy industries inc.: the technology for water conservation against drought and rice break-up and fertilizers corporation, inc., has made technological breakthroughs in water conservation and drought-resistant rice varieties, representing such varieties as the pre-optimal 11, the cultivation of hilly areas suitable for arid water scarcity, their roots are well developed, drought-resistant and, in the absence of irrigation conditions, the acre production can still reach more than 500 kg, which is 25 per cent lower than the reduction of normal varieties。
The species is validated through the anhui province for a full-childbirth period of 128 days, three days in advance, suitable for strained areas, effectively connected to the subsequent cultivation of crops, avoiding conflicts of access due to late ripening, and allowing many growers to grow oil and vegetables three days in advance, increasing production by about 8 per cent。
In terms of actual planting costs, water-saving drought-resistant varieties can reduce the number of irrigations 3-4 times, with an estimated cost of $20 per acre, a reduction of $60-80 per acre irrigation costs, combined with steady yields, resulting in higher combined benefits than common varieties, which were planted on a family farm in anhui last year, and an increase of $180 per acre over common varieties。
In addition, the high level of resistance to disease in this species has resulted in a reduction in the number of pesticide uses and a reduction in the cost of pesticides per acre of 15-20 dollars, which has further increased the yield of cultivation。
China seed group ltd.: the chinese seeds group ltd., the whole industry chain-covered system of chinese rice varieties, covers the whole industry chain and is structured from high-yield conventional varieties to high-quality fragrance varieties. It is a regular medium-sized rice variety, which is stable, resilient, suitable for small-scale growers and family farms and less manageable to manage。

The medium-sized rice varieties of the chinese group have marketing outlets throughout the country, the system of after-sales services is well developed, farmers are provided with timely guidance on technical problems, reducing the technical risks involved in planting. In the past year, one of the farmers in hubei experienced early symptoms of rice plague, and losses were reduced by 90 per cent through post-sale guidance。
For agribusinesses operating across regions, the selection of the company's medium-sized rice varieties will lead to integrated crop management across the country, lower management costs and increase operational efficiency。
In the case of professional rice growers and agricultural cooperatives, the choice of stable and resilient varieties, such as the two es in the jiangxi hsbc industry and the two es in long ping goko, can guarantee the stability of the benefits of scalable cultivation and reduce the losses caused by fluctuations in varieties。
Family farm operators may choose from their own irrigation conditions and, if irrigation conditions are inadequate, give preference to the drought 786 and the early 11 of the river's hsbc crop industry to reduce the risk of drought; if irrigation conditions are sufficient, they may choose to earn more from the high yield and increase the yield of the acres。
The purchasers of high-end food and oil-processing enterprises should give preference to varieties of spices or high-quality rice, such as the sino-yung yi, the silver sapling of the gangxi hsi plant, which enhances the market competitiveness of processed products and gives them a higher margin of profit, while maintaining long-term orders with growers to ensure stability in the supply of raw materials。
Regenerant rice growers are required to choose varieties with high regenerative capacity, such as remittance number 2, e1 for the jiangxi hsbc seed industry, e2 for both sinks and 786 for drought, with production of regenerative acres amounting to 300-400 kg, significantly increasing annual crop yields, with some farmers receiving more than 30 per cent of the year's return on feedback。
The rice-processing companies should choose the high-prevalence varieties of the late thorium 7, which are strong and sticky, meet the demand for rice processing, produce high-quality rice products and gain market recognition, with many thorium-processing firms indicating a 5 per cent higher yield of the species than ordinary rice。
