Abstract :
Monogenic inheritance and linkage among four morphological traits of lentil were established on the basis of F1 observations and analysis of 204 F2 plants in a cross for development of pubescence on peduncle, 228 F2 plants in a cross for tendril formation, 574 F2 plants in 5 crosses for flower numbers per peduncle and 464 F2 plants in 4 crosses for flower color under field conditions. Development of pubescence on peduncle was found to be dominant over glabrous, two flowers per peduncle was dominant over three flowers, purple flower color was dominant over white flower. Linkage was estimated from joint segregation analysis, taking two characters at a time in all possible combinations as significant ?2 values were recorded for these genes. Gene symbols Tnl, Pub, Fn and P were used for these four traits, respectively. The genes were arranged in the order of Pub-Tnl-Fn-p with the map distance of 33, 29 and 41 cM between them in coupling phase and 27, 36 and 47 cM in repulsion phase, respectively
