Inheritance and linkage relationships of days to flower and morphological loci in lentil (Lens culinaris Medikus subsp. culinaris)

Abstract

Lentils from south Asia differ markedly in days to flower and several other traits from lentils in other major lentil producing areas of the world such as west Asia. Single-gene inheritance and a polygenic system were observed to control days to flower in lentil (Lens culinaris Medikus subsp, culinaris), Early flowering was determined by a single recessive gene (sn), Early flowering transgressive segregants occurred in F-2 populations due to the interaction of sn and minor genes for earliness, Pubescent peduncle (Pep) was inherited as a single gene dominant to glabrous peduncle (pep), Tendrilless leaf (tnl) was controlled by a single gene recessive to tendrilled leaf (Tnl), The Sn, Sep (seed coat pattern), and Pep loci were linked together in linkage group 5 and Tnl was linked with Gs (colored stem) in linkage group 1 of the lentil genome.
