| 摘要: |
| 用５个品种分别与不育株连续回交，获得了５个稳定的不育系和相应的保持系。不育系花瓣较小，花丝较短，无花粉粒，雄蕊位于柱头下方。不育系自交不结铃或自交铃脱落；不育系异交，当代结实良好。测交种试验表明：２９个组合中，２６个组合完全不育１３个组合可育，其可育度为９８％～１００％。 |

| A Preliminary Study on Male Sterile Lines of Nucleoplasm Cotton |
|
|
| Abstract: |
| Five steady male sterile lines of nucleoplasm cotton have been contained
with 3 continue backcrossing of varieties and make sterile plants.Characters of flowers
on male sterile lines are smaller petal,shorter filament and no pollen grain and steamen
under pistil.While male sterile lines selfcrossing,there is no cotton boll.While crossing,
there are great cotton bolls.Fruits of cross breed test state:26 cross combinations are
sterile and 3 cross combinations are fertile in 29 combinations.Fertility is 98%～100%. |
