describes the evolutionary aspects and agronomic potential of this important pulse with emphasis placed on wide hybridization, including molecular aspects and future breeding strategies. The existing variability among cultivated germplasm has been exploited to reach a desirable level of productivity. However, to attain further breakthroughs in increasing yield and improving stability in future cultivars, new sources of genes/alleles need to be identified and incorporated into cultivated varieties. This book provides specific use information, including wild lentil germplasm utilization, thus allowing for the selection of transgressive interspecific recombinants that can be adapted to specific environments.
