Description Legume crops are important components of sustainable agricultural
production, household income and dietary systems. However,
legume production in the tropics is challenged by a number
of biotic (diseases and pests) and abiotic (heat, and drought)
stresses. With support from bilateral projects such as Tropical
Legumes (TL1, TL2 and TL3), CGIAR centers together with national
research partners devoted resources and time to address
these challenges. Genetic resources such as reference sets,
pre-breeding, magic and intraspecific mapping populations, as
well as genomic resources such as comprehensive genetic maps,
whole genome sequences, QTLs and trait-specific markers have
been developed for tropical legume crops such as chickpea,
groundnut, common bean, pigeonpea, soybean and cowpea. Besides,
integrated breeding approaches including high throughput
genotyping and phenotyping platforms, marker-assisted selection
(MAS) in pedigree breeding schemes, marker-assisted
backcrossing (MABC) and marker-assisted recurrent selection
(MARS) have contributed to accelerated development of breeding
lines and varieties. Improved varieties have been released
and disseminated together with integrated crop management
practices. Innovative seed and associated technology dissemination
systems including public-private sector partnerships,
community seed production initiatives, quality declared seed,
mini seed packs, contractual seed production, and revolving
seed fund, among others, were used to popularize these varieties.
This has resulted in enhanced adoption and subsequent improvement
in productivity. More efforts are needed to enhance
genetic gain by reducing time required for cultivar development
through application of genomic and phenomic tools, enhancing
selection intensity through automation, mechanization and digitization,
and increasing the crossing scale and number of cycles
per year.
