Legumes and oilseed crops are a rich source of protein and energy. The
major objectives in grain-legume breeding are to increase grain yield,
protein quantity and quality and digestibility, and to decrease toxic
fac tors, seed hardness and cooking time. Similarly, oilseed crops such
as brassicas and peanut share somewhat similar genetic improvement
goals, but suffer from susceptibility to a number of pathogens and
diseases. In spite of the best efforts through conventional breeding,
their yield has been virtually static, with no significant breakthrough.
The lack of genetic variability in the base population has been
considered to be a major limiting factor for the slow progress made in
the improvement of these crops. The desired goals can be achieved by
incorporating addi tional genetic variability in the existing germplasm.
The protein and oil contents which are genotypically oriented can be
enhanced further by suitable crosses. In this regard, progress made
during the last decade, in the area of in vitro manipulation and
recombinant DNA technology, holds promise for the improvement of these
crops. Among the oilseed crops, Brassica spp., soybean and sunflower
have been well studied, wherein haploids, somaclones, somatic hybrids,
cybrids and transformed plants have been produced. Oilpalm is one of the
best examples where micropropagation is being commercially prac ticed.
Regarding legumes, though there is extensive work on forages, such as
Medicago and Trifolium, much needs to be done on food legumes."
