Abstract

Soybean seed quality and appearance influence the desirability of seed in the consumer market. It has been reported that seed coat colour and hilum colour are affected by the genes controlling pubescence and flower colour. To achieve concomitant improvement of seed quality and yield in practical plant breeding, it is necessary to explore the genetics of inheritance of seed quality characters in soybean. In this study, chi-square test was used to analyse the inheritance of four traits i.e. seed coat colour, hilum colour, pubescence colour and flower colour in the F2 derived seed of five crosses made using nine soybean genotypes. Seed coat colour depicted simple monogenic inheritance as the ratios 3:1 and 9:3:4 fitted in three crosses i.e. DT-21 × BHATT, AGS-25×JS- 335 and PS-1556× EC- 389148. Hilum colour expressed several phenotypes that obeyed simple monogenic ratio of 3:1 and 9:3:4 in crosses DT-21 × PS-24, PS-1347×PS1241 and DT-21 × BHATT. Purple flower colour dominated over
