Abstract

With the object of evolving a dormant high yielding bunch type, crosses were affected between Ah8279 (bunch type) and TMV. 3 [Spreading type) and a derivative Ah 5254, was identified and evaluated in the different research centres as well as in the farmers holdings both under reinfed and Irrigeted conditions for a number of years. The yield dete indiceted that Ah 8254 is widely adaptable and may be grown throughout Tamil Nadu. This culture recorded an average yield of 1031 kg/ha as compared to 897kg) ha for TMV. 9 under reinfed condition. Under summer irrigated condition, it recorded 1748kg/ha as against 1394kg für TMV. 9. The yield increases were 15% and 25% under rainted and irrigered conditions respectively. In cultivators holdings Ah 8254 recorded upto 30% increased yield over TMV, 9 under irrigated condition. In shalling out-turn, it was superior with 74% as compared to 71% of TMV, 9. In oil content also, Ah 8254 (50.4%) exceled TMV. 9. (488%) recorded 26% higher ail production per hectare than TMV. 9. It was released as Co. 1 groundnut variety.
