Capturing hybrid vigor for lentil breeding

Hybrid vigor in science.

When I was president of the U.S. National Academy of Sciences, I came to believe that the future success of humanity may depend on learning to use the tools of science—including the collection of objective evidence on what works and why—at all levels of decision-making. Thus, the National Academies have repeatedly addressed questions such as “How can we make a science out of education?” or “How...

Alternative Hypotheses of Hybrid Vigor.

Hybrid mimics and hybrid vigor in Arabidopsis.

F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics o...

Molecular Breeding for Ascochyta Blight Resistance in Lentil: Current Progress and Future Directions

Lentil (Lens culinaris Medik.) is a diploid (2n = 2x = 14), self-pollinating, cool-season, grain legume that is cultivated worldwide and is highly valuable due to its high protein content. However, lentil production is constrained by many factors including biotic stresses, majority of which are fungal diseases such as ascochyta blight (AB), fusarium wilt, rust, stemphylium blight, anthracnose, ...
