Grain Yield and Adaptability of Cajanus cajan New Varieties

9 new varieties of Cajanus cajan were tested at Yuanjiang County,Lushui County and Yunxian County,Yunnan province,with a local variety as CK.The grain yield and adaptability of the varieties were analyzed.V7,V5 and V6 were the most desirable varieties for their good stability,low variation and obviously higher seed yield than the CK.V 10,V3,and V2 produced higher grain yield and higher variation than that of the CK,their release should be on suitable environment.The grain yield of V8,V1,and V9 were lower than that of the CK,but V1 and V9 had the best qualities such as big pods and seeds,as well as their green seeds were sweeter than pea,so V1 and V9 could also be released in thir suited districts.The analysis on the domino effect of site showed the ideal environment like Lushui for pigeonpea cultivation.
