A field experiment was conducted during Kharif season of 2022 at the Experimental Farm of Department of Horticulture, School of Agricultural Sciences, Medziphema Campus, Nagaland University to evaluate different genotypes of sponge gourd for their growth, yield and quality under foothill condition of Nagaland. Twenty three (23) genotypes of sponge gourd were evaluated in randomized block design with three replications. The experimental material comprised 23 genotypes i.e., NUSG-21-1, NUSG-21-2, NUSG-21-3, NUSG-21-4, NUSG-21-8, NUSG-21-10, NUSG-21-11, NUSG-21-13, NUSG-21-15, NUSG-21-16, NUSG-21-18, NUSG-21-19, NUSG-21-20, NUSG-21-21, NUSG-21-22, NUSG-21-23, NUSG-21-24, NUSG-21-25, NUSG-21- 26, NUSG-21-27, NUSG-21-29, NUSG-21-31 and Kashi Divya. Studies showed that among all the genotypes, genotype NUSG-21-18 exhibited maximum vine length (4.67 m), average fruit weight (334.67 g) and yield (185.67 q ha-1). Genotype NUSG-21-4 taken shortest time to produce 1st male flower (39.33 days) and genotype NUSG-21-21 taken shortest time to produce 1st female flower (43 days). Ascorbic acid content in fruit was found to be highest (5.16 mg 100g-1) in genotype NUSG-21-19. Whereas, maximum TSS (4.13⁰B) was found in genotype NUSG-21-20. Based on the experimental findings, it can be concluded that genotype NUSG-21-18 was proved to be potential yielder over other genotypes under foothill condition of Nagaland.

“…Traits such as fruit diameter, which exhibit high heritability but moderate genetic advance, suggest limited potential for further improvement due to the presence of both additive and non-additive gene activity. Pradhan et al [21] reported similar findings for fruit traits in the F4 generation of bitter gourd, while Sravani et al [22] and Kannan et al [23] found comparable heritability values in the F2 and F4 generations of ridge gourd, respectively.…”

The bottle gourd is an important summer vegetable in India, but its productivity is hindered by biotic and abiotic stresses, challenging growing conditions and the lack of high-yielding varieties. Therefore, it is essential to understand its genetics to develop high-yielding cultivars. A thorough understanding of genotypic and phenotypic variability, heritability and genetic advance is necessary for a successful crop improvement program. Research conducted during the spring-summer and rainy seasons of 2021–22 at CCS HAU, Hisar, on the F3 and F4 generations of the bottle gourd cross GH-28 × Pusa Santushti, showed variability in various yield and yield-contributing traits. The fruit yield per hectare showed high values for genotypic coefficient of variation, phenotypic coefficient of variation, heritability and genetic advance in both generations, with progeny 4 performing best in yield-related traits fruit length (44.33cm and 41.17cm), average fruit weight (882.00g and 832.67g), number of fruits per vine (7.20 and 6.07) and fruit yield per plot (63.65Kg and 50.37Kg) was superior in both F3 to F4 generations, respectively. The observed changes in genetic variability across generations suggested heterozygosity, which may stabilize once homozygosity is achieved in later generations. Additionally, correlation analysis indicated that number of primary branches (0.778 and 0.904), average fruit weight (0.974 and 0.856), number of fruits per vine (0.995 and 0.682), days to first harvest (-0.624 and -0.784) and days to first female flower opening (-0.926 and -0.661) directly affected fruit yield per hectare in F3 and F4 generations, respectively. Similar traits were shown to influence fruit yield by path analysis studies Thus, selecting for these traits could significantly enhance a breeding program's success.

“…Notably, for all quantitative traits, the genotypic coefficient of variation consistently appeared lower than the phenotypic coefficient of variation, suggesting the influence of environmental factors on the expression of these traits.

The research conducted at AICRP on vegetable crops, Mahatma Phule Krishi Vidyapeeth, Rahuri during 2022-2023 studied on genetic studies in the F5 generation of ridge gourd (Luffa acutangula L. Roxb.) with the aim of developing a superior and high-quality inbred line. The study employed a randomized block design (RBD) with three replications, using five parents and their respective progenies derived from the cross (Arka Sumeet x Konkan Harita). The findings indicated moderate genetic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV), combined with high heritability and notable genetic advance as a percentage of the mean for specific traits in the F5 generation. These traits encompassed the number of branches per vine, the node of first appearance of female and male flowers, the number of harvests, fruit diameter, fruit yield per vine, fruit yield per plot and fruit yield per hectare. On the contrary, characteristics like vine length, days to initial female and male flower appearance, days to 50% flowering, sex ratio, days to initial and final harvest, fruit length, fruit weight and number of fruits per vine displayed high heritability but showed moderate to low genetic advance as a percentage of the mean. Correlation analysis revealed a significant and positive association between fruit yield per vine and various growth-related characteristics, including vine length, number of branches per vine, number of harvests, days to final harvest, fruit length, fruit diameter, fruit weight, number of fruits per vine, fruit yield per vine and fruit yield per plot. Conversely, a notable and negative correlation was observed between fruit yield per vine and several reproductive traits, such as days to initial appearance of female and male flowers, node number at which the first female and male flowers appeared, duration until 50% flowering, sex ratio and days until the initial harvest.
