Patterns of pod and seed growth during fruit development in garden pea genotypes

Ten garden pea genotypes which were sub-grouped into five early and five mid-season types were utilized for studying the sequence of pod and seed growth during their development. The sequence of changes in fresh and dry weight of pods and grains, and growth in terms of length and width of developing pods were evaluated. The increase in length was significant till 30 days after flowering in all genotypes except GP-17, in which significant increase in pod length was noticed till 25 days after flowering. Pod width increased till 30 days after flowering in all genotypes except GP-4 in which increase in pod width was observed till 35 days after flowering. Fresh weight of the developing pod increased significantly till 35 to 40 days after flowering in different genotypes, while the fresh weight of grains per pod increased significantly till 40 days after flowering. Dry weight of the developing pod and grains increased continuously till 45 days after flowering in all genotypes.
