Single dominant gene controls glabrous trait in vegetable soybean accession ‘AGS-406’

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.
