Experimental Study on Glutinous Variety Improvement of Maize Population Yuzong 5

The representative samples were selected from Yuzong 5,and the methods of field planting and indoor measuring were employed for investigation and data processing on 894 plants of Yuzong 5.The results showed that the coefficients of variation about some traits of 894 plants were as follows: ear height(19.9%); panicle weight(35.1%); ear length(18.1%); ear row number(19.7%); number of kernels per row(22.5%); grain weight per panicle(36.3%); ear diameter(11.1%).It was found that there was large variation in these traits for various plants which could represent Yuzong 5 for glutinous variety improvement.

豫综5号糯质化改良取样可行性分析

[目的]分析豫综5号糯质化改良取样的可行性,明确选取的样品是否具有代表性。[方法]采用田间种植、室内测量等方法对豫综5号的894个单株进行调查和数据处理。[结果]894个单株穗位高变异系数为19.9%,单穗重变异系数为35.1%,穗长变异系数为18.1%,穗行数变异系数为19.7%,行粒数变异系数为22.5%,单穗粒重变异系数为36.3%。[结论]这些性状在各单株之间变异比较大,能够代表豫综5号进行糯质化改良。
