“…In the present investigation, the characters viz., number of female flowers vine -1 X14-100 seed weight X21-Fruit yield vine -1 viz., days to final harvest (-0.6352), number of fruits vine -1 (-0.1735), number of male flowers vine -1 (-0.1482), days to 50 per cent flowering (-0.1459), fruit length (-0.1344), vitamin C (-0.1257), number of primary branches vine -1 (-0.0867), fruit girth (-0.0531), 100 seed weight (-0.0179) and crude protein (-0.0122) had registered negative direct effect on fruit yield vine -1 (Table 3) (Fig 2). Chithra et al [20] reported through a path coefficient analysis on 40 sponge gourd genotypes that the fruits vine -1 , fruit weight and length, branches vine -1 and vine length had positive effects on fruit yield vine -1. This result is also in line with the findings of Hemant and Ajay [21], Rajawat et al [8] and Kalpana et al [6] in cucurbits. Therefore, a direct selection on these traits would be rewarding in yield improvement programs of ridge gourd.…”

“…It implies that the characters strongly influence the yield vine -1 and hence selection for these traits would be considered important in selection of hybrids for yield. Similar findings have been reported earlier by Ananthan and Krishnamoorthy [5] in ridge gourd, Kalpana et al [6] in bottle gourd and Yadagiri et al (2017) in bitter gourd, Sampath and Krishnamoorthy [5] and Krishnamoorthy and Avinashgupta [7] in pumpkin, Rajawat et al [8] in cucumber.…”

This study aims to explore the relationship between several traits among 18 ridge gourd hybrids. It was carried out during the rabi season of 2021–2022, at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, U.T. of Puducherry. Twenty yield-related qualities were assessed using a randomized block design with two replications in order to determine the associations among various characters. The yield per vine was found to have a highly significant and positive correlation with the following variables: vine length at final harvest, number of primary branches vine-1, number of female flowers vine-1, days to final harvest, fruit length, fruit girth, number of seeds fruit-1, total number of harvest, number of fruits vine-1 and weight of individual fruit. Path analysis revealed that the characters such as number of female flowers vine-1, days to first female flower anthesis, total number of harvest, sex ratio, total soluble solids, days to first male flower anthesis, vine length at final harvest, number of seeds fruit-1, days to first harvest, number of primary branches vine-1, fruit length, fruit girth, number of seeds fruit-1, number of fruits vine-1 and weight of individual fruit are considered as important traits which directly and indirectly influences towards yield. It implies that the characters strongly influence the yield vine-1 and hence selection for these traits would be considered important in selection of hybrids for yield.

Cucumber is traditionally cultivated in India and is recognized as a primary centre of origin, belonging to the gourd family, Cucurbitaceae. The study focused on assessing genetic variability in F3 and F4 cucumber populations and examining correlations among various characters including ToLCNDV resistance. In both F3 and F4 generations, per cent disease index, fruit weight and vine length exhibited high heritability and genetic advance as per cent of mean. In F4 generation, yield per plant, fruit girth, fruit length, number of branches and number of fruits per plant also showed high heritability and genetic advance as per cent of mean. Yield related traits viz., sex ratio, number of fruits per vine, yield per plant and vine length exhibited complementary gene action. Days to first harvest and crop duration demonstrated negatively skewed distribution suggesting duplicate gene action and rapid genetic gain under selection. Leptokurtic distribution in yield per plant and associated traits implied the involvement of few genes for genetic inheritance of the above traits. Significant positive associations were found between yield per plant and number of fruits per plant, fruit weight and number of branches per plant suggesting potential early selection for these characters to enhance overall yield.

Variability and character association studies for yield and yield contributing characters in cucumber (Cucumis sativus) under low hills of Himachal Pradesh

Cucumber is an important member of family Cucurbitaceae having potential applications across many sectors. Twenty genotypes were evaluated at the Department of Vegetable Science, College of Horticulture and Forestry (Dr Yashwant Singh Parmar University of Horticulture and Forestry), Neri, Hamirpur, Himachal Pradesh during June– September 2021 for studying variability in morphology, yield and its contributing traits. In studying genetic parameters, PDI of downy mildew, number of fruits/plant, total yield per plot and PDI of powdery mildew, traits showed high estimates of PCV and GCV, indicating the considerable amount of variation was present in germplasm. Most of the traits under study showed high heritability with high to moderate genetic advance as a per cent of mean, which showed the influence of additive gene action for controlling traits. Thus, selection is effective for improvement in these cucumber genotypes. Correlation association and path analysis showed fruit length, fruit breadth, internodal length, number of fruits per plant, harvest duration and ascorbic acid. These traits were considered during the selection of superior genotypes among the twenty genotypes. Thus, in this study, LC-C-4-21 and LC-C-14-21 were higher yielders and can be used for further breeding programmes.
