我所1975年正式开展长绒棉新品种选育工作,目前已经获得一批较好的品系.这些品系在1978年的试验中,产量超过邻近对照20%左右,霜前花超过95%,铃重、绒长、衣分接近或超过对照的有13个;有3个品系参加南疆1979年国家区域试验,其中2个在各试点中的结铃性均居第一、第二位.下面谈谈我们工作中的几点体会. In 1975, we formally carried out the breeding of new varieties of long staple cotton and now we have obtained a number of better lines, whose production exceeded the adjacent control by about 20% in 1978 and exceeded 95% There were 13 heavy and cashmere long and close to or surpassing the control, and 3 strains participated in the national regional test of South Xinjiang in 1979, of which 2 were the first and the second in the pilots.
