Assessing genetic potential of elite interspecific and intraspecific advanced lentil lines for agronomic traits and their reaction to rust (Uromyces viciae-fabae)

Abstract

The narrow genetic base of lentil (Lens culinaris) has challenged the efforts of breeders to increase its productivity under changing environmental conditions. Inclusion of wild species and diverse cultivated genotypes offers an opportunity to generate new variation through wide hybridisation to broaden the genetic base of cultivated lentil. We evaluated 96 elite, interspecific (L. culinaris × L. orientalis) and intraspecific advanced lentil genotypes along with four checks to determine the extent of genetic variation, resistance to lentil rust (Uromyces viciae-fabae), and the nature and magnitude of their genetic divergence. Sufficient genetic variability was revealed for all of the traits...
