Identification of Glutinous Rice Landraces and Selection of Elite Germplasm in Jiangxi Province
摘要
Abstract
Based on The Third National Survey and Collection of Crop Germplasm Resources,along with subsequent supplementary collections,a total of 216 glutinous rice landrace germplasm resources were obtained from Jiangxi province.The distribution patterns and germplasm types of these resources were analyzed,and their morphological characteristics,agronomic traits,and quality characteristics were evaluated.A comprehensive assessment and selection of superior local glutinous rice germplasms were carried out.From the perspective of geographical distribution,the glutinous rice landrace germplasm resources in Jiangxi province are mainly concentrated in five less developed regions:Shangrao,Ganzhou,Fuzhou,Ji'an and Yichun.These landraces exhibited high genetic diversity and harbored two subspecies:indica and japonica,with indica being the predominant type.Additionally,these resources can be categorized into early,medium,and late varieties according to their maturity,with medium and late rice varieties predominating.Moreover,the seed coat color varies widely,and eight colored glutinous rice resources were identified.Most of the spikelets are yellow,with either no or short awns,suitable panicle,moderate blade and stem angles,resistance to lodging,and suitable seed holding.These characteristics indicate great potential for further utilization.Through two years repeated evaluation of the agronomic and quality traits of local rice resources in Jiangxi province,ten glutinous rice germplasm resources were selected,which showed large panicles,multiple grains,high seed setting rate and high 1000-grain weight.Among them,the effective number of panicles per plant ranged from 8.2 to 10.3,the number of grains per panicle ranged from 183.4 to 236.6,the 1000-grain weight ranged from 23.2 to 27.2 g and the seed setting rate ranged from 84.3%to 94.0%.These germplasm resources have the characteristics of high yield and good quality,which have considerable values for breeding application.These elite germplasm resources selected in this study have great potential for further utilization,which could provide a material basis for the genetic improvement of high yield and quality in glutinous rice.关键词
