从1976年起,我们经过多年选择和品种鉴定,终于从[(荆4×冈1)F_1×荆4]F4的杂交后代中选育出较好的棉花新品种“72—22—28”,它不仅比鄂光棉突出增产,而且品质优于鄂光棉。1981年,“72—22—28”在省内6个县和3个国营农场集中扩大繁殖和20多个县进行生产示范,种植面积达2万亩以上。现将该品种的选育经过、试种情况和栽培要点,介绍如下。 品种选育与鉴定 Since 1976, after years of selection and variety appraisal, we finally bred a better new cotton variety “72-22-28” from the hybrid progenies [(Jing 4 × Gang 1) F_1 × Jing 4] F4, It is not only higher than the E-cotton, but also better quality than E-cotton.
