Maturity group classification of soybean varieties with molecular marker in Huang-Huai region
摘要
Abstract
Maturity group (MG)is a main method for the classification of soybean varieties based on character-istic of growth period.47 of the major local and new soybean varieties of Huang-Huai region were identified and classified with 13 MG standard varieties from the USA.Three simple sequences repeat (SSR)markers Satt431, Satt215 and Satt557,associated with soybean MG,were used in this study.The results showed that 31 soybean va-rieties belonged to MGIV,accounted for 65.95%,6 and 10 soybean varieties were classified into MGIII and MGV, accounted for 12.77% and 21.28% respectively.13 varieties including Meng1157 -1,Meng1158 -1 and Xu9302-204 etc.could be classified into the same MGs in 2013,2014 and 2015,accounted for 27.66%.The variation of climatic factors had less effect on soybean growth period for these varieties.47 varieties were identified with SSR markers Satt431,Satt215 and Satt557,and the accurate rate of markers assisted selection for MGIII and MGV were 83.33% and 90.00% respectively.In addition,the genotypes of soybean varieties belonged to MGIV were more complicated than those of other MGs.The number of growing days of the tested varieties were between 96 and 104,their plant height were between 46.22 and 85.90 cm,their nodes of main stem were between 12.20 and19.04.The plant height and nodes number of main stem of tested varieties had the smallest coefficient of variancein 2014.Their average plant height and their nodes number of main stem showed positively correlation with MGII -MGIV,but negative with MGV.The results of this experiment could provide a foundation for soybean growth periodclassification based on the genotypes of MGs.关键词
