豌豆品种高寒适应性评价

在甘肃省皇城绵羊育种试验场，于1998－1999年期间，观察了3种引进一年生豌豆（Pisum sativum）品种在高寒环境条件下的生长表现。结果表明，3种豌豆均能适应当地的气候条件，并能完成整个生育期。其中中豌8号生产性能最佳，其蛋白质含量、产草量和种子产量均高于其它2种豌豆，分别为25．89％、7．92t/hm^2、3．9t/hm^2，可作为高寒牧区的优良一年生豆科牧草。而饲用豌豆瘤体粉色，有效固氮的根瘤多于另外2个品种，在改良和培肥土壤方面潜力更大。

Adaptability evaluation of three pea varieties in alpine region

Performance of three introduced annual pea varieties:Pisum sativum(CV Zhongwan No.8,CV Forage pea,CV Zhongwan No.4)was studied under alpine , s environment of Huangcheng Sheep Breeding Experimental Farm from 1998 to 1999.The results showed that all three varieties could adapt the local climate condition and finish the maturity development. Zhongwan No.8 performed best among the three,the seed protein content,forage yield and seed yield were 25.89%,7.92 t/hm 2 and 3.9 t/hm 2 respectively,which were higher than the other two,it could be used as one of the perspective legume variety in alpine region.The higher available nodule number with forage pea indicated that this variety is suitable to impove soil fertility.
