Abstract

This research was conducted in 2022-23 at the Vegetable Research Block, situated within the esteemed College of Horticulture at Dr. Y.S.R. Horticultural University in Venkataramannagudem, Andhra Pradesh, India. The principal objective of this study was the assessment of growth and yield-related traits in both parent and hybrid snake gourd varieties. Among the six parent varieties scrutinized in this investigation, specifically IC 347377, Kaumudi, and PKM-1, the recorded yields were 12.06 kg, 9.79 kg, and 9.42 kg per vine, respectively. In contrast, the hybrid varieties, namely Manusree × CO-2, PKM-1 × CO-2, CO-2 × IC 212513, and PKM-1 × IC 347377, exhibited remarkable yields, producing 20.25 kg, 18.84 kg, 18.02 kg, and 15.95 kg per vine, respectively, in the cultivation of snake gourd. These findings underscore the promising potential of the parent varieties for inclusion in future breeding programs, offering avenues for the enhancement of snake gourd characteristics. Concurrently, the high-yielding hybrid varieties, distinguished by their impressive productivity, are strongly recommended for broad adoption within the commercial cultivation of snake gourd. This research outcome contributes substantial insights to the domain of snake gourd cultivation, providing valuable guidance to growers and breeders for the purpose of informed decision-making aimed at elevating crop productivity.

Conclusion

In summary, following a comprehensive examination of six distinct parental varieties, Manusree and CO-2 have unequivocally emerged as strong general combiners, distinguished by their substantial contributions to both fruit yield and quality-related characteristics. These two varieties have consistently displayed exceptional performance across multiple key attributes, underscoring their significance in breeding programs aimed at enhancing the overall quality and productivity of the crop. Among the specific crossbreed combinations, Manusree × Kaumudi has exhibited exceptional characteristics in terms of fruit length and average fruit weight, demonstrating a synergistic effect that augments these essential quality metrics. Conversely, PKM-1 × Manusree has proven to be highly effective in enhancing fruit girth, while Manusree × CO-2 has shown remarkable potential in terms of both the number of fruits per vine and overall fruit yield per vine. These findings represent a valuable foundation for future breeding initiatives, offering essential insights and benchmarks for the development of improved snake gourd varieties. The selection of strong general combiners and the identification of specific cross combinations with desirable traits provide a structured approach to advancing the crop's genetic potential, ultimately benefiting the agricultural sector and ensuring the continued progress of snake gourd cultivation.
