Genetic Correlation Analysis of Ear Traits in Maize Inbred Lines of Five Major Heterosis Groups
摘要
Abstract
In order to study the genetic relationship of panicle traits among heterosis groups and inbred lines in one group,we adopted spilt-plot design and selected ten typical maize inbred lines in each heterosis group,which had five heterosis groups totally,to perform descriptive statistics and variance analysis.Further-more,the correlations among panicle traits in maize inbred lines of five heterosis groups and their relations with single ear grain weight were analyzed.The results showed that the coefficient of variation of inbred lines in Lancaste group was larger.There were significant differences in ear length,ear diameter and ear row num-ber between the heterosis groups,and the characters of ear length,ear weight,bald tip length,ear diameter, axis diameter,grain weight and so on were significantly different between the maize inbred lines in each heter-osis group.The correlation between ear weight and single ear grain weight in each dominant group was very sig-nificant;the rate of seed and single ear grain weight was correlative but the correlation was not significant;the bald tip length and single ear grain production was negatively correlated but it was not significant.关键词
