Abstract

Vegetables are considered as essential one for a well-balanced diet. Karaikal is one of the regions of Union Territory of Puducherry located in the East Coast, almost at the end of the Cauvery Delta Zone. Diversification of cropping as an alternate to paddy is highly recommended for augumenting the farmers income and to sustain farming in this region. However, identification of suitable crop and variety to suit the existing soil and climatic conditions becomes essential. Since sponge gourd is grown in negligible areas despite its tremendous nutritional and diversified utility due to the lack of awareness of this crop and less concerted effort on crop improvement programmes, it was chosen and the present investigation was carried out to study the per se performance of different bitter gourd hybrids in the Coastal condition of Karaikal for various growth and yield attributes. The study materials comprised of 21 different sponge gourd genotypes assembled from various parts of the country and was performed at the Department of Horticulture, Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry, India. The study revealed the presence of significant differences among the genotypes evaluated for all the growth and yield contributing characters observed. Among the 21 genotypes, Ranking based on per se performance, revealed that the genotype Kashi Sheya was the best among the 21 genotypes evaluated. It recorded better performance 12 characters out of 16 characters. The genotype Pusa Sneha which ranked second excelled in performance for seven characters. The genotype L.C-13 which ranked third exceled in performance for the six characters. The present study suggested that among the 21 sponge gourd genotypes evaluated, the genotype Kashi Shreya was found to be the best for yield and other yield related traits followed by Pusa Sneha and L.C-13. These genotypes can be further utilized in crop improvement programme for yield and other yield related traits in coastal region of Karaikal.

Conclusion

Ranking based on per se performance, revealed that the genotype Kashi Sheya was the best among the 21 genotypes evaluated. It recorded better performance for number of primary branches vine-1 (6.31), number of nodes vine-1 (48.42), node of first staminate flower (2.33), node of first pistillate flower (7.21), days to first staminate flower anthesis (26.01), days to first pistillate flower anthesis (28.82), sex ratio (18.83), fruit length (35.60), individual fruit weight (379.18), number of fruits vine-1 (23.82), total soluble solids (2.84) and fruit yield vine-1 (8.91). The genotype Pusa Sneha which ranked second excelled in performance for the traits viz., sex ratio (11.61), number of fruits vine-1 (26.06), number of primary branches vine-1 (5.19), days to first pistillate flower anthesis (27.82), individual fruit weight (349.13), fruit yield vine-1 (23.82) and number of nodes vine -1 (54.04). The genotype L.C-13 which ranked third exceled in performance for the traits viz., crude fibre (0.57), node of first staminate flower (2.55), days to first staminate flower anthesis (29.29), number of primary branches vine-1 (4.61), individual fruit weight (338.23), fruit yield vine-1 (5.41). The present study suggested that among the 21 sponge gourd genotypes evaluated, the genotype Kashi Shreya was found to be the best for yield and other yield related traits followed by Pusa Sneha and L.C-13. These genotypes can be further utilized in crop improvement programme for yield and other yield related traits in coastal region of Karaikal.
