CARACTERIZAÇÃO BOTÂNICA E AGRONÔMICA DE ACESSOS DE FEIJÃO-FAVA, EM MOSSORÓ, RN

Abstract

The objective of this work was to assess the agronomic performance and plant morphological traits of eight lima-bean (Phaseolus lunatus L.) accessions in the edafoclimatic conditions of Mossoró, RN, Brazil. A randomized complete blocks design with eight treatments and four replications was used. The treatments consisted of the BSF 01, BSF 02, BSF 04, BSF 07, BSF 08, BSF 08A, BSF 12 and BSF 15 lima-bean accessions. The following traits were evaluated: growth habit, mean time of blooming, pod length and width, number of pods per plant, number of seeds per pod, weight of 100 seeds and seed yield. It was observed that all lima-bean accessions were of indeterminate growth habit, except for BSF 07B and BSF 12 that show determinate growth habit. BSF 12 and BSF 15 accessions were, respectively, the earliest and the largest seed size. They was not distinction between the lima-bean accessions for pod length, but significant differences were observed on pod width, with BSF 12 and BSF 02 accessions showing the highest and the less width. The accession BSF 01 can be the best alternative for Mossoró country growers because this material had higher number of pods per plant and higher seed yield. The accessions BSF 04, BSF 07B and BSF08 are potentially useful for lima-bean because these materials had higher number of pods per plant, higher seed yield and characteristics of pods satisfactory.
