Inheritance and linkage of leaf colour and plant pubescence in lentil (Lens culinaris Medik.)

Published on

Inheritance of leaf colour and plant pubescence in lentil
(Lens culinaris Medik.) was studied using six and three
crosses, respectively. Observation on 1037 F2 plants for
leaf colour revealed a segregation ratio of 3 (dark green):
1 (light green). The F3 family data also fitted well to the
ratio of 1 (dark green): 2 (segregating): 1 (light green)
leaf colour. Individual 1735 F
2 plants were observed for
plant pubescence which segregated in the ratio of 3
(pubescent): 1 (non-pubescent). The F3 family data showed
a ratio of 1 (pubescent): 2 (segregating): 1 (non-pubescent).
The results revealed the involvement of single dominant
gene for both the characters and gene symbols Dgl and
Pub are proposed for them. Joint segregation analysis
resulted In a significant, X2 L value for these loci indicating
their linkage with a map distance of 29.66 ± 0.012 in
Kosambi Unit.
