以农业农村部"第三次全国农作物种质资源普查与收集行动"为契机,开展了广西壮族自治区紫云英(Astragalus sinicus L.)种质资源的考察收集与评价鉴定.结果表明,收集到的58份地方资源主要分布在桂东北以及0~400 m的中低海拔地区.12项农艺性状表型分析显示其遗传多样性丰富;主成分分析将12个农艺性状分为3个主成分,分别为种子产量、生物产量及生育期特征,累计贡献率达72.089%;通过加权平均计算得出综合排名前 10位的种质资源为GXLF20180011、GXLF2019109、GXLF2019156、GXLF2019118、GXLF2019112、GXLF2019117、GXLF20180006、GXLF2019125、GXLF2019111、GXLF2019136;排名前10位的种质资源全生育期为134~147 d,盛花期茎粗(直径)为2.83~3.66 mm,盛花期株高为 41.63~54.73 cm,单株分枝数为 2.83~4.19个,每分枝花序数为 5.85~6.99个,总花序数为17.55~26.23个/株,结荚花序数为14.33~19.97个/株,鲜草产量为10 458.15~48 792.75 kg/hm2,干草产量为1 037.36~5 724.34 kg/hm2,种子产量为246.75~991.20 kg/hm2.
Collection and phenotypic diversity evaluation of local Astragalus sinicus L.germplasm resources in Guangxi
Taking the opportunity of the"Third National Crop Germplasm Resources Census and Collection Action"of the Ministry of Agriculture and Rural Affairs,the investigation,collection,evaluation and identification of Astragalus chinensis L.germplasm resourc-es in Guangxi were carried out.The results showed that the 58 collected local resources were mainly distributed in the middle and low altitude areas of 0~400 meters in northeastern Guangxi.Phenotypic analysis of 12 agronomic traits showed rich genetic diversity.Prin-cipal component analysis divided 12 agronomic traits into 3 principal components,namely seed yield,biological yield,and growth pe-riod characteristics,with a cumulative contribution rate of 72.089%.By weighted average calculation,the top 10 germplasm resources in the comprehensive ranking were GXLF20180011,GXLF2019109,GXLF2019156,GXLF2019118,GXLF2019112,GX-LF2019117,GXLF20180006,GXLF2019125,GXLF2019111,and GXLF2019136.The total growth period of the top 10 germplasm resources was 134~147 d,with stem diameter of 2.83~3.66 mm during the peak flowering period,branch length of 41.63~54.73 cm during the peak flowering period,branch number per plant of 2.83~4.19,flower number per branch of 5.85~6.99,total flower number of 17.55~26.23 per plant,pod bearing flower number of 14.33~19.97 per plant,and fresh grass yield of 10 458.15~48 792.75 kg/hm2,hay yield of 1 037.36~5 724.34 kg/hm2,and seed yield of 246.75~991.20 kg/hm2.
