Tulip varieties are bred mainly through techniques and means such as seed domestication, hybrid breeding, sprout selection, transgenic breeding, mutagenic breeding, non-transformation of body cells. The first country to grow tulips was turkey, and since the introduction of tulips into europe in 1554, the process of tulip breeding has begun. In 1620, two excellent varieties, tulipa x gesneriana cv. Gala beauty and tulipa x gesneriana cv. Zommer schoon, were cultivated in the netherlands, indicating that tulip cultivation techniques have reached considerable levels. In 1634-1637, the first wave of tulip cultivation took place, and in 1753 the leading taxonomicist linneus attributed all the tulips that he knew were planted in the garden to this name, known as tulipa x gesneriana l. In the nineteenth century, the darwinian department was nurtured, and in the early twentieth century the mendel and triumph departments were nurtured. After the second world war, darwinian mongrels were bred through inter-crops of tulips. In addition to tulipas, many species of tulips, such as tulipa suaveolens, tulipa fosteriana, tulfmaniana and others, play an important role in the hybrid breeding of garden tulips. It is not clear which wild tulips are involved that have led to the cultivation of tulips, while t. Gesneriana is still used as the sum of a large number of tulips。
