玉米株型性状的杂种优势研究
Heterosis of Plant-type T raits in M aize
摘要
Abstract
In this experiment ,eight maize hybrids and their parents from different sources were used as materials to study the heterosis of plant-type traits .The results showed that most of the plant-type traits in F1 generation were highly correlated with their female parents ,but were not correlated with their male parents ,except the stem diameter of the third internode .In all the plant-type traits ,five had relatively high heterosis in F 1 generation ,including the plant height ,ear height ,tassel length ,stem diameter of the third internode and leaf area .关键词
