| Popis: | Knowing and characterizing the preserved genetic heritage contributes to the development of new plant cultivars. The objective of the present work was to characterize morphologically, in greenhouse, lines of common bean obtained from the cultivar 'BAT-93'. Variations were found in the shape of the leaf, predominant color of the hypocotyl, color of the main stem, color of the flower and color of the seed and not for the characters: color of the legume, texture of the legume and degree of curvature of the legume, which remained similar for all the lines. The main variations were observed in the color of the flower and the seed, with values above 60% in comparison with 'BAT-93'. Violet, white and violet, yellow and white flowers were observed. In the plants from red and black seeds, the color of the hypocotyl and the stem was red and in the case of the plants from brown and marbled seeds, the hypocotyl and the stem were green similar to 'BAT-93'. It was observed that the leaves with apices with lobed margins was the type of variation that predominated in the lines coming from red, black and brown seeds. The variability described in the lines obtained in the first generation, suggests studies of agronomic characters and genetic stability. Keywords: common bean, ex vitro conditions, qualitative characteristics, phenotypic variations |
