Inheritance and Correlation Analysis of Main Agronomic Traits in Mungbean (Vigna radiata L.) by Mixed Linear Models
摘要
Abstract
There are only few reports about the genetic research of agronomic traits of mungbean in China. The objectives of this experiment were to study the inheritance and correlation of main agronomic traits of mungbean (Vigna radiata L.). Through incomplete diallel cross of 19 mungbean varieties (lines), we analyzed the breeding data by mixed linear models. The results revealed that additive genetic effects were mainly responsible for growing period, plant height, node number of main stem, and 100-seed weight. The narrow-sense heritability of the four traits was high with significant level. Additive and dominant genetic effects were responsible for pod number per plant, yield per plant and total yield. The narrow-sense heritability of the three traits was low. Dominant genetic effects were responsible for seed number per pod, and the broad-sense heritability of it was high. Days to flowering was significantly and positively correlated with plant height at both phenotypic and genotypic levels. Number of pods per plant and seeds per pod were significantly and negatively correlated with 100-seed weight, but number of pods per plant was positively correlated with yield per plant and total yield. There was no correlation between 100-seed weight and yield. As a result, the selection should be at early generations for growing period, plant height, node number of main stem and 100-seed weight, but at late generations for yield according to number of pods per plant and yield per plant.关键词
