| 摘 要： | 我们于1987年对雌株玉米的产量构成因素进行了通径分析。试验结果表明,穗粒数是雌株玉米的增产关健,其中雌株顶穗的穗粒数与顶穗的穗粒重r_(X~(2M))=0.9879,P_(M·X~2)=0.9439;雌株腰穗粒数与雌株腰穗的穗粒重r_(X5N)=0.9999,P_(N·X5)=1.1528。而千粒重却是雌株后代正常玉米产量构成至关重要的因素,其r_(X9B)0.9095,P_(B·X9)=0.6648。

| Abstract: | We Were finding the Gynomonoecious maize at 1971. It is Without Pollen, the terminal tassel and waist ear are Single Sex Pistillate floW er. There are many Long Styles on the terminal tassel and Waist ear, these many styles can be cross Pollintion.The Proportion of Gynomonoe cious to normal Plants is 1:1 at the test cross or sister cross genera tion. This Composition is Path-Coefficient analysis of individual Plant yield component of Gynomonecious maize.The results indicated that spikelets Per Panice single Plant is key charactor to dependantthe grain yield of the Gynomonoecious maize. However, the 1000-graine weight is key factor at the normal plant. |
