AVALIAÇÃO DAS CARACTERÍSTICAS DE PRODUÇÃO DE HÍBRIDOS ORIUNDOS DO CRUZAMENTO ENTRE ICATU E CATIMOR CONDUZIDOS COM IRRIGAÇÃO

Abstract

O Objetivo deste trabalho foi de avaliar a produtividade, o rendimento e a renda de híbridos originados do cruzamento entre o Icatu e o Catimor em ambiente irrigado, por duas safras consecutivas, na região de Uberlândia-MG. As plantas foram cultivadas na Fazenda Experimental do Glória, pertencente à Universidade Federal de Uberlândia, no espaçamento 3,5 m entre linhas de plantio e 0,7 m entre plantas na linha. O delineamento experimental utilizado foi o de blocos casualizados com três repetições. Os tratamentos constituíram-se de vinte e seis linhagens de Icatu x Catimor: H 19-5-14-16, H 26-6-5-16, H 29-1-3-8, H 29-1-7-18, H 29-1-8-5, H 29-1-8-16, H 29-1-9-11, H 29-1-14-9, H 30-2-6-11, H 30-3-14-18, H 30-2-6-16, H 30-3-14-19, H 32-3-15-19, H 32-11-17-4, H 39-1-5-4, H 39-1-11-12, H 68-7-12-6, H 83- 8-11-14, H 84-3-7-19, H 86-1-7-5, H 86-1-7-11, H 138-1-9-10, H 136-1-13-15, H 136-1-14-9, H 136-1-19-16 e H 136- 1-19-4. Os resultados encontrados evidenciaram que os híbridos H 39-1-5-4, H 30-3-14-19, H 30-3-14-18 e H 30-2-6- 11 apresentaram os melhores resultados quanto à produtividade, rendimento e renda.The purpose of this study was to evaluate the yield, the profit and the recovery of hybrids originated from the crossing between the Icatu with Catimor in irrigated environment, for two consecutive years in the region of Uberlândia-MG. The plants were cultivated in the Experimental Farm of Glória, owned by the Federal University of Uberlândia, in the 3.5 m spacing between planting rows and 0.7 m between plants in row. The experimental design was a randomized block design with three replications. The treatments consisted of twenty-six strains of Icatu x Catimor: H 19-5-14-16, H 26-6-5-16, H 29-1-3-8, H 29-1-7-18, H 29-1-8-5, H 29-1-8-16, H 29-1-9-11, H 29-1-14-9, H 30-2-6-11, H 30-3-14-18, H 30-2-6-16, H 30-3-14-19, H 32-3-15-19, H 32-11-17-4, H 39-1-5-4, H 39-1-11-12, H 68-7-12-6, H 83- 8-11-14, H 84-3-7-19, H 86-1-7-5, H 86-1-7-11, H 138-1-9-10, H 136-1-13-15, H 136-1-14-9, H 136-1-19-16 and H 136-1-19-4. The results showed that the hybrids H 39-1-5-4, H 30-3-14-19, H 30-3-14-18 e H 30-2-6-11 were those that presented the best results for the yield, profit and recovery.
