Produtividade de grãos e óleo de genótipos de amendoim para o mercado oleoquímico

Top lines and cultivars of runner peanut genotypes were analyzed as to grain and oil yield, aiming further recommendation to edible or combustible oil market. The genotypes were cultivated during wet seasons for two years, at the city of Barbalha, state of Ceara, Brazil, by using a complete randomized block design with five replicates. The harvest took place from 110 to 135 days after planting. Pod, grain and oil yields were registered in each plot. Crude oil was extracted by soxhlet protocol, by using petroleum ether as a solvent. Afterwards, fatty acids were analyzed by gas chromatography. Based on yield tests, LViPE-06 and BRS Perola Branca showed the highest grain yields, with pod and seed yield averages of 3.04 kg ha-1 and 2.13 kg ha-1, respectively. These genotypes also stood out as to oil chemistry industry, based on oil content and ratio of oleic/ linoleic fatty acids, which were 51 and 1.9, respectively.
