玉米氨基酸含量的杂种优势分析

Analysis of Heterosis on Amino-Acids of Maize

采用 6个母本、4个父本 ,按NCⅡ设计 ,配制 2 4个杂交组合 ,对 16种氨基酸含量的杂种优势进行了分析。结果表明 :F1中各种氨基酸含量 ,有的表现出正向杂种优势 ,有的为负向杂种优势。并对各种氨基酸间的相关、亲子相关进行了研究。

The heterosis of the content of 16 amino acids were analyzed through 24 crosses made among ten inbred lines of maize (6 females and 4 males) using incomplete parallel cross design. The results showed that the heterosis of the content of some amino acids were high; while for some the values were negative. The correlation between parents and hybrid for amino acids, and between various amino acids were studied.
