Abstract

The selection of common bean lines for seed coat standard, sanitary and physiological quality seed is recent in breeding programs. The objectives of this research were to evaluate if common bean lines differ for seed coat standard, sanitary and physiological quality seed, to investigate the correlation between these characters and to select common bean lines with high seed quality. For this, 16 inbred common bean lines were evaluated in normal rainy growing season. The common bean lines showed significant difference for the weight of thousand seeds, seed coat color, lignin content, length, width and thickness seeds, Fusarium sp. incidence, germination, first germination count, accelerated ageing, length of shoot, root and total of seedling, dry matter of shoot and total of seedling and emergency of seedling in field. A positive correlation coefficient was found between emergency of seedling in field and germination (r = 0.650), first germination count (r = 0.600), accelerated ageing (r = 0.793) and electric conductivity (r = 0.635). The indirect selection by germination, first germination count and accelerated ageing is effective to identify common bean lines with the highest emergency of seedling in field and germination. The selection of TB 02-07, SM 1810, Carioca, LP 08-90, SM 1107, LP 07-80, Pérola, CNFP 10104 and TB 02-24 lines is recommended for use in controlled hybridization programs for improvement of news common bean cultivars of high seeds quality.
