Componentes de produção, produtividade e atributos tecnológicos de cultivares de feijoeiro do grupo comercial carioca

Abstract

In the National Register of Cultivars of the Ministry of Agriculture, Livestock and Supply are registered about 350 cultivars of bean. Bean cultivars, in addition to adaptation to the growing site, should present productive potential and meet the consumers' demands regarding the qualitative attributes. The objective of this study was to evaluate the production, productivity and qualitative attributes of bean cultivars of Carioca commercial group during the autumn-winter period, in order to obtain information on productive capacity and grain quality, with characteristics that meet the producers and also the consumers. The experimental design was a randomized block design, with 13 treatments and 4 replicates. The treatments consisted of the bean cultivars: Perola, BRS Estilo, BRSMG Madreperola, BRS Notavel, IAC Alvorada, IAC Imperador, IAC Milenio, IPR 139 (Juriti Claro), IPR Andorinha, TAA Bola Cheia, TAA Dama, TAA Gol e ANfc 9. All common bean cultivars stood out for grain yield, but BRSMG Madreperola, IAC Milenio, IAC Alvorada, TAA Dama, ANfc 9 and BRS Estilo obtained values ​​above the general average of 3,460 kg ha-1. The bean cultivars TAA Dama and BRS Estilo presented interesting characteristics in terms of productivity and grain quality, being suitable for both the producer and the consumer. The cultivars BRSMG Madreperola, IAC Milenio, IAC Alvorada and ANfc 9 presented high productivity and technological quality of the grains, but with time for maximum hydration higher than that used in brazilian cuisine.
