选种学发展初期,某些棉花选种家曾有一种不正确的意见,认为中亚细亚热量不足,不能栽培细绒棉.实际上,这一棉种的外来原种种子所以晚熟低产,是不适应当地发育条件所致.从一九二五到一九二六年起,在南土库曼穆尔加布河谷开始了各种生态型的大量细绒棉种的田间试验.播种材料是各地在比原产地温度更低的新条件下获得的样本.这些样本机体内,旧的遗传性削弱了,并形成了繁杂而带有动摇遗传性的类型.
In the initial period of germplasm selection, some cotton germplasmists once had an incorrect opinion that there is not enough calorie in Central Asia to grow fine cottons. In fact, the exotic seeds of this cotton variety are so late-maturing and low-yielding that they are not Adapted to local development conditions, a large number of ecologically-based varieties of flocks of fine-fiber cotton were started in the southern Turkmen Murgaib valley from 1925 to 1926. The sowing material Samples obtained under newer conditions of lower temperature in the origin where the old heredity was weakened and formed a complex and somewhat hereditary type.
