甘肃箭筈豌豆种质资源评价

通过对甘肃42份箭筈豌豆（Vicia sativa）种质资源进行研究评价，以期为甘肃绿肥种植筛选优良的箭筈豌豆品种。结果表明，42份箭筈豌豆种质资源各性状指标存在明显差异，其中单株荚数和单株粒数是构成箭筈豌豆产量的主要要素。籽粒产量、鲜草产量、单株粒数和单株荚数4个指标可以反映箭筈豌豆性状的优劣。通过籽粒产量、鲜草产量、单株粒数和单株荚数4项指标进行聚类，可以分为4类，Ⅰ、Ⅱ类相对较好，共有7份材料，籽粒和鲜草产量分别在2 623.26～2 990.25和32 357.70～35 967.38 kghm-2，其中苏箭3号、陇箭1号和333/A属于早熟品种，麦类作物收获后的套复种、玉米(Zea mays)前期间作、马铃薯(Solanum tuberosum)绿肥间作、果树绿肥间作和单种绿肥5种利用模式均适宜；山西春箭碗和MB5/794属于中熟品种，则适宜与马铃薯间作、果树间作和单作；西牧820和波兰箭碗属于晚熟品种，则只适宜与果树间作和单作两种利用方式。

Evaluation of Vicia sativa germplasm resources in Gausu

In the present study, germplasm resources of 42 Vicia sativa varieties were evaluated to screen optimal V. sativa varieties for planting green manure in Gausu. Results showed that there were obvious differences in the tested trait indices of germplasm resources of 42 V. sativa, in which pods per plant and grains per plant were the main elements of V. sativa production. Four indices including grain yield, fresh yield, grains per plant and pods per plant indicated characteristics of V. sativa which can clustered these 42 varieties into four groups. Seven varieties belonged to groupⅠ and groupⅡ which had grain yield and fresh yield of 2 623.26～2 990.25 and 32 357.70～35 967.38 kgha-1, respectively. Sujian 3, Longjian 1 and 333/A belonged to early maturing varieties which were optimal for five culture including intercropping and multiple cropping after wheat crops harvest, early maize intercropping, green manure intercropped with potato, green manure intercropped with fruit tree and green manure monocropping. Shanxi spring V. sativa and MB5/794 belonged to mid maturing varieties which were optimal for intercropped with potato, and fruit tree and monocropped. Ximu 820 and Polish Vicia sativa belonged to late maturing varieties which were optimal for intercropped with fruit tree and monocropped.
