摘要： 为筛选出适宜青海半干旱和高寒区种植的优良豌豆(Pisum sativum)资源，本研究选取10份豌豆种质资源，系统评价供试豌豆资源的13个农艺性状及产量在同仁(半干旱区)和泽库(高寒区)种植区的田间表现。结果表明：10份豌豆种质的表型变异范围在同仁为3%~24%，在泽库为7%~23%。其中，荚数(24%)和每荚籽粒数(23%)的变异系数最高；10份豌豆种质资源在同仁和泽库农艺性状存在差异，且泽库‘A-61’豌豆的干草和种子产量最高，同仁49豌豆干草产量、‘中原5号’种子产量最高；灰色关联度分析表明，84豌豆和‘A-61’豌豆分别在同仁和泽库种植区综合性状最优。因此，‘中原5号’和49豌豆可分别作为同仁地区饲用型和种用型豌豆种质资源，而‘A-61’豌豆可作为泽库地区饲用型兼种用型豌豆种质资源。

Abstract: Ten pea germplasm resources were selected to screen out superior Pisum sativum germplasms with high adaptivity for cultivating in semi-arid (Tongren) and alpine (Zeku) regions of Qinghai province through systematically evaluating their 13 agronomic traits and yield of these cultivating P. sativum germplasms. These results showed that:1) Phenotypic variation change of 10 P. sativum germplasms ranged from 3% to 24 % in Tongren and 7% to 23 % in Zeku. Both the number of pods (24 %) and seeds per pod (23 %) demonstrated the highest coefficient of variation. 2)10 P. sativum germplasms had different agronomic traits between Tongren and Zeku. It is noted that ‘A-61’ germplasm achieved the highest hay and seed yield in Zeku,while Tongren 49 and ‘Zhongyuan 5’ germplasm harvested the maximum forage and seed yield,respectively. 3) Results of grey correlation analysis indicated that 84 and ‘A-61’ germplasm demonstrated the optimum comprehensive traits in cultivating Tongren and Zeku,respectively. Therefore,‘Zhongyuan No.5’ can be the candidate P. sativum germplasm to forage production while 49 germplasms to seed production in Tongren. By contrast,‘A-61’ was recommended as one of the superior P. sativum germplasm simultaneously achieved higher forage and seed production in Zeku.
