摘要
1991年在北京对两个陆地棉中长绒杂交组合、一个一般陆地棉杂交组合和两个陆海杂交组合 F_1的研究表明:陆地棉中长绒杂交种可以把高产和优质有机地结合在一起,其皮棉产量超过陆地棉对照品种中126%和3%,纤维长度、细度和强度仍保持中长绒亲本水平,基本接近陆海杂交种的各项指标。
Reaserch on heterosis for cotton hybrids F_1 of two intraspecific mid-long staple lines(Gossypium hirsutum L.),one intraspecific hybrid F_1(G.hirsutum L.)and two inter- specific hybrid F_1(G.hirsutum L.,G.barbadense L.)were conducted in Beijing in 1991.The results showed that the mid-long staple hybrids were able to conbine the high lint yield and high fiber quality,the lint yield of the two hybrids excess the control Zhong Mian 12 for 6% and 3%.The fiber length.finess and strength remain the level of long fiber parents and ap- proach the quality of hybrids between G.hirsutum L.and G.barbadense L.
