对47份来自四川的小豆地方品种资源进行了形态多样性的调查研究和性状相关性分析,结果表明:①四川小豆地方品种的生长习性以直立型为主;②与产量密切相关的株高、主茎分枝数、单株荚数、单荚粒数和百粒重等性状的变异系数均较大,依次为单株荚数(24.68%)>百粒重(23.71%)>株高(21.06%)>主茎分枝数(19.75%)>单荚粒数(14.13%);③四川小豆种质资源具有丰富的形态多样性,平均多样性指数为1.529。④全生育期与单株产量呈显著正相关,主茎分枝数、荚长、单株荚数和百粒重均与单株产量呈极显著正相关。
The results showed that: ①The growth habits of adzuki bean landraces in Sichuan Province was mainly erect type; ② The plant height, The coefficient of variation of main stem branch number, pod number per plant, single pod grain number and 100-grain weight trait were all larger, followed by pods per plant (24.68%)> 100-grain weight (23.71%)> plant height 21.06%)> the number of main stem branches (19.75%)> the number of single pods (14.13%); (3) The germplasm resources of Sichuan Adzuki Bean were rich in morphological diversity with the average diversity index of 1.529. ④ The whole growth period was significantly and positively correlated with the yield of single plant. The number of stems, length of pods, number of pods per plant and weight per plant were significantly and positively correlated with the yield per plant.
