Abstract

The glabrous pods or grey pubescence is highly preferred trait for the vegetable soybean cultivars since the appearance of the cooked pods is clean compare to brown or dark pubescence pods. The genetic control of trichomes is thoroughly studied in cotton and Arabidopsis with very limited information in soybean particularly in variants of vegetable types. Inheritance of this traits was worked out by utilizing glabrous vegetable soybean genotype ‘AGS- 406’ that was crossed with normal pubescence cultivar ‘AGS- 346’ and ‘Swarna Vasundhara’, the commercially released cultivar of vegetable soybean in India. The observed segregation ratio of the F2 population fitted to the expected ratio of 3:1, and the glabrous phenotype was found to be controlled by a single dominant gene.
