| 摘 要： | 为了选育高产优质的玉米品种,同时为了了解各农艺性状与产量间的相互关系。本试验以68个玉米杂交品种为供试材料,采用随机区组设计,通过对此68个杂交种的产量比较以及主要农艺性状的综合比较分析,选出了高产、优质的杂交种武314/2117。另外对千粒重、穗长、穗粗等十几个农艺性状的相关系数和通径系数的分析表明,对产量影响最大的因素是穗粒重。

| Abstract: | We carried out the experiment in order to select maize hybrids and to understand the relation between grain yield and main agronomic characters .Sixty-eight maize hybrids were tested by using a Randomized Compete Block Design. The result of the yield and agronomic characteristics of maize hybrids showed that wu 314/2117,1508/2122 was higher yield with good agronomic characters and also showed that ear row grain was the most importance to grain yield . |
