| 摘 要： | 对华杂4号及其不育系1141A遗传改良前后的生育特征与产量结构进行对比研究,结果表明,改良后的不育系986A及其F1代华杂5号在主要形态指标、干物质积累以及产量性状等方面均优于不育系1141A和华杂4号,尤其是不育系986A与1141A相比在株高、叶片数、分枝数、角果数和产量等主要经济性状上有了显著提高,从而为制种产量高的986A不育系的应用和华杂5号的进一步推广提供了理论依据。

| Abstract: | The growth and development and yield components of improved variety "Huaza No.4 " and 1141A were studied . The results showed that major morpholigies and dry matter accumulation and yield characters of "Huaza No.5 "and 986A were obviously improved, especially for the plant height and numbers of leaves and branche and pod, yield of 986A compared with 1141A.It provided theoretical basis on further demonstration and popularization of the variety Huaza No.5 and 986A. |
