春大豆EMS诱变M1、M2代主要农艺性状的遗传变异及相关性
Genetic Variations and Correlation of the Main Agronomic Characters in M1 and M2 Population of Spring Soybean Induced by EMS
摘要
Abstract
Seven spring soybean varieties were treated by 0.5% EMS (ethylmethane sulphonate) solution, and analyzed genetic variations and correlation of the main agronomic characters in M1 and M2 generation. Morphological variation of M1 was mainly induced by mutagens which made the plant physiological process into disorder. Among the characters of M2, the genetic variation coefficient of branches, pods per plant, seeds per plant and seed weight per plant were more evident. For the broad sense heritability plant height, main stem nodes were the highest; branches, seeds per plant, seed weight per plant and pods per plant were medium and 100-seed weight was the lowest. EMS could advance or delay soybean growth duration, in the earlying growth duration, the early mature varieties were evident than late mature ones, while no significant difference were observed for delaying maturation between early and late mature soybeans. Among the primary varieties, significant correlation between plant height, main stem nodes and seeds per plant, pods per plant, seed weight per plant were observed, while this trend not found in M2 generation.关键词
