Description In the present investigation, inheritance of seed size was
studied in a cross involving two small-seeded kabuli cultivars,
ICCV 2 and L 550. Mean 100-seed weight (100 SW) of
parents and that of their F1 generation were similar. However,
transgressive segregants were obtained in F2 generation in
both directions. Considering the segregation pattern, plants
in F2 and backcross generations were divided into three
groups, 100 SW less than F1/parents (F1P1P2). The numbers of plants in the three
groups in F2 fitted well to an expected ratio of 5:6:5 (χ2 = 2.15, P = 0.34), and in backcross generations to an expected
ratio 1:2:1 (χ2 = 0.94, P = 0.33 in BC1P1, and χ2 = 3.89,
P = 0.14 in BC1P2), which suggested that seed size in
the two parents is controlled by two genes exhibiting additive
effects with each parent having one pair of alleles with
increasing effect at one locus in homozygous form.
