BRS 151 L-7: a new peanut cultivar recommended to the Brazilian Northeast conditions

Abstract

BRS 151 L-7 is a new large seeded and red testa color peanut cultivar, developed by Embrapa-Centro Nacional de Pesquisa de Algodão and destined to in natura consumption and food industry. This cultivar is an erect type plant, and was obtained by hybridization between a high yield Valência genotype (IAC-Tupã) and a short-season cultivar from Senegal 55-437 (Spanish). In 27 regional yield trials, where evaluation is made under different agroecological conditions in four states of the Brazilian Northeast, BRS 151 L-7 showed high seed yield potential, short cycle (87 days), tolerance to drought and adaptation to semi-arid environment. The average pod yield in the rainy season was about 1.85 ton ha^-1 and in irrigated conditions it was 4.50 ton ha^-1, which correspond to 12% and 38% increase, respectively, in relation to traditional Tatu. As nutritional aspect, BRS 151 L-7 is low oil content (46%) and high protein in its defatted flour (55%). Among essential amino acids, the cultivar is only limitant in lisin, when compared with FAO/85 pattern.
