| 摘 要： | 为探究绿豆生育期性状遗传特性,以早熟材料‘VC2917’为母本(P1),晚熟材料‘鹦哥绿’为父本(P2),构建的包括261个株系的RIL群体为材料,在4个生境条件下对群体的开花期和成熟期进行调查和遗传力分析。结果表明,在4种生境下,母本和父本的开花期均值分别为53.8 d和41.0 d,群体的开花期平均为47.4 d,最大值为61.8 d,最小值为35.3 d;两亲本成熟期均值分别为83.1 d和56.3 d,群体内成熟期平均为72.3 d,最大值为90.0 d,最小值为48.8 d;群体的开花期和成熟期均呈正态分布且两个亲本和群体的开花期和成熟期差异显著;其广义遗传力分别为0.955和0.954。以上结果表明,绿豆开花期和成熟期是一个受主效基因控制的数量性状。

| Abstract: | In order to explore the genetic characteristics of mungbean growth stages, the RIL population consisting of 261 strains constructed using ‘VC2917’ (an early maturing local variety) as the female parent (P1) and ‘Pinker Green’(a late maturing local variety) as the male parent (P2) were used as materials for the investigation of traits and heritability analysis in the flowering and maturity periods of the population under four ecological conditions. The results showed that, under the four ecological conditions, the flowering period of P1 and P2 were 53.8 d and 41.0 d, respectively. The average flowering period of 261 strains was 47.4 d, the maximum was 61.8 d, and the minimum was 35.3 d. The maturity periods of the P1 and P2 were 83.1 d and 56.3 d, respectively. The average maturity period of population was 72.3 d, the maximum was 90.0 d, and the minimum was 48.8 d. The flowering and maturity period of RIL population were both normal distribution. There was significant difference of flowering and maturity periods between two parents and RIL population. The broad-sense heritability of the flowering and maturity period was 0.955 and 0.954, respectively. It was illustrated that the flowering and maturity period of mungbean were both quantitative traits controlled by major genes. |
