Title Application of molecular markers in cool season food
legumes breeding
 
Creator Coyne, C J

Subject Food Legumes
 
Description As the marker density has increased in linkage maps of the food legumes over the last ten
years, many markers closely linked to economic traits, both qualitative and quantitative
inherited, have been identified and published. Typical with other crops, soybean and maize
for example, application of marker assisted selection (MAS) in food legumes has been
aggressively pursued primarily by private institutions, due to costs and the more basic nature
of public institutions research missions. However, developments in recent years have
contributed to increases in both the utility and application of MAS in public and private
institutes breeding and germplasm enhancement programs. These developments include diJ(ectly: (1) the development of PCR -based markers, sequence-tagged sites and co-dominant
microsatellite markers available for pea, chickpea, lentil per se and the development of crosstaxa
markers from Medicago truncatula and Lotus japonicus, (2) the reduction in costs of the
MAS technology, and indirectly (3) increases in genomic tools such as the construction of
legume EST and BAC libraries and sequencing of Medicago truncatula and Lotus japonicus,
along with the elucidation of plant gene functions, particularly from Arabidopsis thaliana.
We will review specific examples of the development status of MAS in pea for biotic stresses,
chickpea for biotic stresses, lentil traits, other food legumes breeding and germplasm
enhancement projects, and conclude with prospects for the future.
