摘要
以长♀、黄♂等6个玉米自交系为亲本,按不完全双列杂交配成15个杂交组合,对其株高、穗位高、穗粒质量等14个主要性状进行配合力和杂种优势分析。结果表明,自交系黄♂穗粒质量一般配合力(GCA)、特殊配合力(SCA)的标准差和总配合力均最大,而且它与其他自交系的组合产量在所有组合中最高,均达到1.95万kg/hm2以上,其中,昌7-2×黄♂最高,达到2.09万kg/hm2。
In this experiment, Chang ♀, Huang ♂ such as maize inbred lines for the six parents, two-out at full hybrid dubbed in15 combinations, height, ear, grain weight per plant, 14 main characters with a force and genetic correlation analysis were studied. The comprehensive study of six with the inbred lines of maize, heterosis of test results showed that Huang♂ grain weight of GCA, SCA and the standard deviation of the total with the biggest, and its combination with other lines of production in all the highest in the portfolio,yields have reached more than 19 500 kg/hm2. Among them, Chang 7-2×Huang♂ was the highest to 20 861.25 kg/hm2.
