Wide crossing or distant hybridization has been used in the genetic improvement of crop plants by developing useful variability for breeding populations in crop. Distant crosses are more successful in more closely related species or genera than in less closely related species or genera. In distant crosses seed setting show very less and main problem depicted flowers and pods shading one or two days after pollination due to incompatibility reaction between both parents. To overcome flower and pod shading with increase seed setting use of plant growth regulator is one of the best option to overcome the problem in wide hybridization. From out of total 24 parents 18 grasspea genotypes and 7 pea genotypes were used under study. The effect of growth regulators with a combination of GA with NAA and Kinetin on pollinated buds peduncle showed the best result as compare to the other possibilities for both the parents grasspea and pea. The daily application of a mixture of growth regulators con
Plant growth regulator, grasspea, interspecific crosses, intergeneric crosses.
The main drawback of this crop is neurotoxin content ODAP content which reduces its highly manageable and valuable crop for poor farmers. It can be eliminated or reduces upto the level of <0.2% by using pure line selection, pedigree method, pre breeding distant hybridization, somaclonal variation and transformation methods so it is one of the best source of protein for people to overcome the malnutrition in developing countries.
