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

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 F₂ 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, χ² L value for these loci indicating their linkage with a map distance of 29.66 ± 0.012 in Kosambi Unit.
