Seleção de genótipos de milho mais promissores para o consumo in natura

Abstract

Six genotypes belonging to the UENF sweet corn improvement program: H43IN, P43, C43, 43IN, HDC and Uenf506-8 were evaluated aiming at identifying those with better agronomic characteristics and preferred for the consumption of corn on the cob. This investigation was conducted from September 2003 to January 2004, following a randomized complete block design, with four replications and two locations. The following agronomic traits were evaluated: yield with straw (PrCP), productivity without straw (PrSP), percentage of commercial ears (EC), length of ears without straw (CESP), diameter of ears without straw (OF) and ears yielding (R). Besides, the consumer preference for the products in relation to the flavor, sweetness, and softness was investigated. The results have shown that one of the most suitable genotype for the corn on the cob consumption considering the agronomic characteristics was the common hybrid Uenf506-8. However, by looking at preference results it was verified that the referred hybrid did not reach adequate acceptance by consumers due to its softness and sweetness. The hybrids H43IN and HDC were considered more suitable for the green corn consumption. © 2006 SBCTA.
