盐碱胁迫下147份大豆种质萌发期耐盐碱性评价及代表性种质的农艺性状评价
Evaluation of salt-alkali tolerance at germination stage of 147 soybean germplasms and evaluation of agronomic performance of representative accessions
摘要
Abstract
In order to investigate the relationship between soybean salt-alkali tolerance at the germination stage and field agro-nomic traits,147 soybean germplasms from different origins were used as materials.A compound salt-alkali solution was formulated based on the ion composition of saline-alkali soil(NaCl∶Na2SO4∶NaHCO3∶Na2CO3=1∶9∶9∶1),and four stress concentrations(90,120,150,and 180 mmol·L-1)were applied.Germination potential,germination rate,seedling length,root length,and fresh mass were measured.The comprehensive evaluation value of salt-alkali tolerance(D value)was calculated using the membership function method combined with weight analysis.Forty-two accessions were selected for field validation in typical soda saline-alkali land in Heilongjiang Province to analyze their yield and quality traits.The results showed that the combined salt-alkali stress significantly inhibited soybean germination and early growth.The salt-alkali tolerance(D value)of the 147 germplasms exhibited abundant genetic diversity.In the field,cer-tain accessions demonstrated good synergy between yield and quality.The tolerance at the germination stage(D value)was positively correlated with field yield and quality.This study provides excellent germplasm resources and scientific evaluation methods for soybean salt-alkali tolerance breeding.关键词
