Abstract

Wild Lens species/subspecies are a potential source for increasing genetic diversity in cultivated lentil. Four intraspecific crosses were attempted between cultivated and wild lentils. Viable hybrids were produced between L. culinaris ssp. culinaris · L. culinaris ssp. orientalis and L. culinaris ssp. culinaris · L. culinaris ssp. odomensis. Normal meiosis and pollen fertility were observed in the first set of crosses, whereas chromosomal abnormalities and reduced pollen fertility were observed in the second set of crosses. These crosses were also studied for some quantitative traits. The range, mean and coefficient of variation were calculated in parents, F1, F2 and BC1 generations to determine the extent of variability generated in the cultivated lentil through introgression of genes from wild lentil. The cultivated lentil · L. culinaris ssp. orientalis crosses showed substantially higher variability for all the traits than crosses involving cultivated lentil · L. culinaris ssp. odomensis. The results of the present study indicated that these wild subspecies can be exploited for breeding purposes and their variation can easily be utilized to widen the genetic base of the cultivated lentil.
