1986年于海、陆棉杂种二代分离群体中发现一雌雄异熟株后,经连续8代选育,已育成性状稳定的陆地棉雌雄异熟系,生育期120天左右,属中熟偏早类型。其主要性状和遗传行为如下: (一)形态特征 雌雄异熟系的株形与普通棉花品种无差异,其形态特征主要表现为:现蕾后雌蕊柱头露出,尔后随着花器生长而逐渐伸长,最终伸出花苞2-4mm,而此时雄蕊则全部被
In 1986, the second generation of Lumian intergeneric segregation population showed a dichogamous strain, after 8 successive generations of breeding, has developed a stable cotton Upland cotton, growth period of about 120 days, is a middle-cooked earlier Types of. The main traits and genetic behavior are as follows: (1) Morphological characteristics Monocluster lines are indistinguishable from those of ordinary cotton cultivars. The morphological characteristics are mainly as follows: the pistil stigma is exposed after budding, and then gradually elongated as the flower grows , Eventually extending bud 2-4mm, while the stamens are all at this time
