Title: Temporal Profiles of Pod Development and Seed Set in Chickpea
Abstract: The pod ontogeny covers the events from appearance of flower bud, anthesis, setting of pods,
development of pod shell, elongation and dry matter accumulation in pod shell, setting of seeds into pod and
growth of grain in terms of length, breadth and width are very critical issues and perhaps the pivotal
phenomenon in determining the yield. Legume seeds develop within the confines of an ovary-derived pod
whose walls provide numerous functions for the seeds. Three desi and three Kabuli genotypes of chickpea
(C. arietinum L.) were evaluated for pod and seed development. The tall growing and profuse branching
genotype PG-9758-6-2 and kabuli genotype Dollar Mexican had relatively low number of pods on secondary
branches. The dwarf genotypes Chafa, Vijay and Virat which have high number of nodes per plant, bear profuse
pods per plant. The maximum width and maximum volume of the seed was completed within 31 to 32 days from
flowering and length and girth were completed within 34 to 35 days from flowering. The maximum dry weight
of the seeds occurred within 42 days. Transition from vegetative to reproductive phase occurred by floral bud
appearance within 32 days. In next five days the buds opened into flowers and within 10 days from flowering
the pod setting occurred. The first pod maturity occurred during 66 days from flowering. The actual average
seed development period for six genotypes was 64.16 days. The effective seed development period is
approximately 29.83 days. The difference of 34.33 days in actual and effective seed development is lag period.
The minimum lag period was in Dollar Mexican (27 days) followed by Virat (29 days) and Chafa (29 days). It was
longest in ICCV-2 (53 days). The total chlorophyll content in pod wall was 0.378 whereas the chl-a content was
0.165 mg/g. It is noticed that Vijay was characterized by highest magnitude of total chlorophyll, chl-a and chl-b
which was closely followed by Chafa and Virat
