Resumo: | Cowpea is a crop that has become socio-economically relevant, mainly in developing countries. Correlation studies are important to determine the association between quantitative traits and yield to guide the selection, i.e., choose direct or indirect selection. The objective was to estimate the correlations between six agronomic traits in cowpea as well as the correlations between the estimates of combining abilities of parents. Genotypes with high pod weight and pod length, 100-grain weight, and number of beans per pod should be used to improve grain yield in cowpea. The breeder should preferably insert plants into his group of crosses that have a high combining ability for pod length, number of grains per pod and yield per plot. |

Os estudos de correlação são importantes para determinar a associação entre caracteres quantitativos e a produtividade, de forma a direcionar a seleção, ou seja, seleção direta ou seleção indireta. Objetivou-se estimar as correlações fenotípicas entre seis caracteres agronômicos em feijão-caupi, assim como as correlações entre as estimativas das capacidades de combinação dos genitores. Genótipos com elevado peso e comprimento de vagem, elevado peso de cem grãos e número de grãos por vagem devem ser usados para melhorar a produtividade de grãos em feijão-caupi. O melhorista deve preferencialmente inserir em seu grupo de cruzamentos, indivíduos com alta capacidade de combinação para comprimento de vagens, número de grãos por vagem e produção por parcela.Brazilian Society of Plant Breeding2019-12-16T13:15:55Z2019-12-16T13:15:55Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCARVALHO, L.
