| 摘 要： | 本研究表明陆地棉幼苗NRA的遗传符合“加性——显性”模式,F_1代表现部分显性;其狭义遗传力很高.幼苗NRA与纤维品质性状和种子生化品质性状无明显关系;与衣分和仁指是极显著正相关,与铃重呈显著负相关.

| Abstract: | The present study shows that the seedling nitrate reductase activity(NRA) in Vpland cotton agrees with the genetic model of " additive-dominant" , and is incomplete dominant in Fl. Its narrow inheri-tability (hn) is high. NRA has no significant correlations with fiber and seed biochemical quality characters, but has highly significant positive ones with lint percentage and seed kernal index, and significant negative one with single boll weight. |
