甜菜苗期抗旱鉴定指标筛选及其综合评价
Study on screening of drought resistance assessment indices and comprehensive evaluation of sugarbeet during seedling stage
摘要
Abstract
Ten traits indices were used for the evaluation of drought resistance of 30 sugarbeet germplasms in green- house during seedling stage under repeated drought stress . Through principal components analysis , five indices , namely leaf length , leaf width, underground biomass stress index , root/shoot stress index , and leaf thickness were screened , which had close relation to the drought resistance . With the membership function method , the drought resistance of 30 accessions of sugarbeet germplasms was evaluated . The correlation coefficient is 0 .989 between the value of comprehensive evaluation and direct evaluation . Based on the value of comprehensive evaluation , the germplasms with strong drought resistance in seeding stage were : HI0466 , BETA812 and ID204 .关键词
