Abstract


Present study is based on three accessions of wild and cultivated plants of Coccinia grandis. As dioecious taxa, separate male and female plants are present. Male plants are present in wild only whereas the female are both wild and cultivated. Both these plants (wild and cultivated) were studied for morphological features, floral phenological events, reproductive efficiency and cytological details in male track. These were tagged at Jammu, Samba and Kathua districts of Jammu province, UT J&K, India. Morphologically, no difference was observed between three accessions of cultivated and wild female plants. In term of sexual reproductive output, wild female vines have high percentage fruit set than cultivated vines in all three accessions. Among three accessions of both wild and cultivated female vines, Kathua accession has more fruit set on open pollination than Jammu and Samba accessions. The species also shows fruit set on bagged flowers which are deprived of pollen, points toward the incidence of apomixis. Cytologically, this species was found to be stable with normal chromosome number (2n = 24).
