高油玉米主要性状的遗传相关性

Genetic correlation of main characters of high oil corn

用 3个高油玉米杂交组合的P1、P2 、F1、F2 、B1、B2 世代 ,采用随机区组设计 ,研究了高油玉米主要性状的遗传相关性 .研究结果表明 ,与产量遗传相关密切的性状依次为穗粗、单穗重、株高、百粒重、穗位高、行粒数、穗长、茎粗和蛋白质 .与籽粒油分遗传相关密切的性状依次为穗行数、百粒重、行粒数、穗长和茎粗、穗位高。

The correlation of major characters of high oil corn were studied with P 1, P 2, F 1, F 2, B 1 and B2 generations of three combinations. The random block design was used in the experiment. The results showed that close relate characters to corn yield were ear diameter, ear weight, plant height, hundred kernel weight, ear position, kernels in ear row, ear length, stalk diameter and the content of protein. And characters of rows in ear , hundred kernel weight, ear length, stalk diameter , ear position and number of leaves were closely relate to the content of oil in kernels.
