| 摘 要： | 通过对滇Ⅰ型杂交粳稻不育系合系42A和榆密15A繁殖产量及其构成因素的分析,结果表明：繁殖产量与结实率、有效穗、穗实粒数及千粒重之间呈极显著或显著正相关关系,合理调控它们之间的相互关系,可以大幅度提高繁殖产量。在生产应用过程中,必须充分掌握不育系的特征特性,根据各个不育系的经济性状进行合理的群体结构调控,才能有效地发掘其增产潜力。

| Abstract: | In this paper,the interrelationship among seed yields and yield components in sterile lines Hexi 42A and Yumi 15A of Dian-CMS type was studied.The results showed that the relationship between yield and four yield components seed(setting ratio,effective spikes,numbers of plump seed,and 1000-grain weight) separately had significant or extreme significant positive correlation.Regulating those correlations effectively will increase the seed yields.It is necessary to understand the characters of sterile lines and make them have stronger structural modulation for getting higher yields so that it is able to develop the inner potential. |
