Affecting Factors and Relevant Marker Study on Peanut Seed Quality
摘要
Abstract
[Objective]To understand the effects of variety,location,meteorological factors and cadmium content on the quality of peanut seeds,develop quality markers for peanut seeds,improve the quality of peanut seeds,and achieve the industrial goal of high and stable yield of peanut.[Method]In this study,different peanut varieties were tested in the northern region,and the quality of peanut seed was analyzed by variance analysis and multiple comparison.With species quality index as dependent variable and meteorological factor as independent variable,stepwise regression analysis was carried out.The correlation between cadmium content of seed kernel and seed quality index was analyzed.Correlation analysis was used to explore molecular markers related to quality of peanut seed.[Result]Varieties,locations,meteorological factors and their mutual effects on the quality of peanut species were very significant.The germination potential,germination rate and germination index in Qingdao were higher than those in other places,and the vitality index in Tangshan was higher than those in other places.Among the 12 small-peanut planting sites,the germination potential of Qingdao was higher than that of other sites,the germination rate of Qingdao and Tangshan was higher than other sites,and the germination index and vitality index of Qingdao were higher than other sites.There was significant or extremely significant negative correlation between cadmium content and 4 seed quality indexes of large peanut.There was a significantly positive correlation between cadmium content and germination index of small peanut in a certain test range.Four seed vitality traits from standard germination tests were correlated with 60 pairs of AhTE markers.The selected markers covered all 20 chromosome sets of peanut,and 9 molecular markers were found to be significantly correlated with peanut seed quality.[Conclusion]There are significant effects of varieties,locations,meteorological factors and cadmium contents on peanut seed quality.Nine molecular markers related to seed quality traits are obtained.关键词
