Variabilidade morfológica e seleção de genótipos de amendoim tipo vagem lisa cultivados por agricultores familiares do Recôncavo Baiano

Abstract

The aim of this study was to evaluate the morphological variability among genotypes of peanut collected from small producers in Recôncavo, unique genotypes (GO), for second stage, get selected genotypes (GS) most promising for future breeding programs. The work was initiated as an experimental area of Empresa Baiana de Desenvolvimento Agricola (EBDA), municipality of Conceição do Almeida, Ba, and subsequently completed in the field of Universidade Federal do Recôncavo da Bahia, in Cruz das Almas, Ba, both located in Recôncavo. The morphological analysis of growth, in both steps proceeded to the non-destructive method from the 21 th day after emergence and for analysis of morphological and vegetable production, 96 days after emergence. It was conclude that the first step was no significant difference between the variable of the genotypes analyzed using Scott-Knott test, except for production characteristics. The results showed low variability, which can be attributed to the mix on morphological characteristics found among and within genotypes. In the second stage, the clustering methods UPGMA and Tocher, identified variability, forming distinct groups. The selected genotypes (GS) 5.2, 6.2, 13.2 and 14.1 showed the best predictors for the criteria evaluated.
