Abstract
Inheritance was studied in natural variants of the soybean cultivar Paraná, developed under photoperiodic conditions ranging from 13 h 31 min day light, at sowing, to 14 h 23 min, 59 days afterwards. Results indicated that early flowering and maturity are controlled by a single dominant gene. Natural mutations that originated cultivars Paranagoiana and SS-1 occurred at the same locus of cultivar Paraná. It was not possible to determine if the recessive alleles of these mutant cultivars are different. The designation E6 was proposed for the alleles determining earliness in cultivar Paraná, and e6 for the gene determining late flowering and maturity in cultivars Paranagoiana and SS-1, until the individuality of the alleles of Paranagoiana and SS-1 is confirmed.

Os resultados indicaram que o florescimento e a maturidade precoces são controlados por um gene dominante. As mutações naturais que originaram os cultivares Paranagoiana e SS-1 ocorreram no mesmo loco do cultivar Paraná. Não foi possível determinar se os alelos recessivos desses cultivares mutantes são separados. Foi proposta a designação E6 para os alelos que determinam o florescimento e a maturação precoces no cultivar Paraná, e e6 para os alelos que determinam florescimento e maturação tardios nos cultivares Paranagoiana e SS-1, até que a individualidade dos alelos de Paranagoiana e SS-1 seja confirmadaKeywords
