摘　　要：为鉴定与筛选优良绿肥用豌豆品种资源。收集我国不同地区的50份豌豆品种及品种资源作为供试材料,经过3年田间试验和室内考种试验,根据豌豆的11项性状指标,采用K-均值聚类分析和相关性分析对豌豆种质资源进行初步评价。绿肥用豌豆叶部性状变异范围大于荚部性状;各指标中,叶片宽的变异范围最大,变异系数为196.68。在划分的5个类群中,1类品种小区鲜草产量≥4.46 kg,籽实产量≥2.45 kg,生育期为88 d左右。豌豆鲜草产量与生育期、叶片长、单株荚数均呈极显著正相关,与荚长呈极显著负相关。籽实产量与生育期、株高、单株荚数、鲜草产量呈极显著正相关。通过综合鉴定与评价,筛选出优质高产品种资源白瓜皮和阿杂山藜豆。Preliminary identification and screening pea varieties of manure used.Utilize fifty representative resources of pea as test materials,over three years of field experiment and test species,use K-means clustering analysis and correlation analysis to evaluate pea germplasm according to eleven pea traits.Range of leaf characteristics is larger than that of pod;Range of variation of leaves wide is 196.68,which is the largest in all indicators.In the 5 groups,fresh yield of varieties of type I ≥ 4.46 kg,seed yield ≥ 2.45 kg,and growth period is 88 d.Pea fresh yield was significantly correlated with growth period,leaf length and pod number,and was significantly negatively correlated with pod length.Seed yield was significantly correlated with growth period,plant height,pod number and fresh yield.Over comprehensive identification and evaluation,selected of Baiguapi and Aza Lathyrus sativus.L as high yield varieties.
