“…Correlation publications pertaining to cucumber has been drastically reduced after 2015. Correlation among various traits in cucumber was previously documented by Solanki and Seth (1980); Rastogi and Rathore (1990); Saikia et al (1995); Singh (1997); Singh et al (2002); Afangideh and Uyoh (2007); Kumar et al (2008);, Kumar et al, (2011), Shet et al, (2018) and Sharma et al, (2018).…”

Pooled data portrays wide range of environmental conditions by reducing the effects of outliers. On that basis, character association and path analysis were studied to assist the selection of traits in breeding approach of Cucumis sativus L. Total of 52 genotypes were evaluated at three locations during 2022 and 2023 at College of Horticulture, Bagalkot, Karnataka, India in RCBD design. The correlation estimates revealed that yield per hectare had significant positive correlation with fruit yield per vine(0.99), fruit yield per plot(0.99), number of fruits per vine(0.75) and vine length(0.38). Parameters like vine length, number of branches per plant, days to first and last harvest, sex ratio, fruit length and diameter, TSS, average fruit weight and yield per plot showed direct positive effect on yield per hectare at genotypic level. This suggested that selection criteria based on these parameters may be effective to improve yield per hectare in cucumber.

“…"It can also show nonuniformity in fruit size, shape, colour, quality and fruit yield. For attaining the uniformity in these traits, a good understanding of genetic stock of Mangalore melon and selection of superior genotypes in segregating populations is very important for any crop improvement programme for the development of new varieties" [4].…”

Correlation and path coefficients analysis can help to assess the mutual relationship between various plant characters and determines component characters on which selection can be based or improvement in yield. 260 Mangalore melon vines were evaluated for yield contributing characters to observe their associations, direct and indirect effect on fruit yield per vine at College of Horticulture, Bagalkot during summer 2021-2022. The study revealed that fruit yield per plant had significant positive correlation number of female flowers, fruit length, fruit width, number of fruits per vine, fruit weight, flesh thickness, seed cavity width and seed cavity length which are important characters to be accounted for gaining improvement in yield. Path analysis revealed that fruit weight exhibited highest positive direct effect on fruit yield per vine followed by flesh thickness, number of fruits per vine, seed cavity length and so on.

“…Extensive research has been conducted worldwide on selecting high-quality cucumber genotypes from seed masses, and well-known cultivars have been introduced to select and evaluate genotypes. In a study on the evaluation of 21 genotypes of cucumber, it was shown that the cucumber length ranged from 5.50 to 20.95 cm with an average of 12.19 cm, and the cucumber width was between 3.00 to 8.30 cm with an average of 5.97 cm, and also, their heritability was 84.36 and 93.23%, respectively (Shet et al 2018). In another research on the genetic evaluation of 38 genotypes of cucumber, the fruit length ranged from 6.57 to 35.71 cm with a mean of 20.73 cm; the fruit width was between 2.25 to 10.71 cm with a mean of 6.44 cm.…”

Genetic variability in a crop population is essential for successful plant breeding. Fifteen cucumber (Cucumis sativus L.) genotypes were evaluated in the greenhouse under the warm condition to estimate the magnitude of their genetic variability and heritability as also morphological and pomological characteristics for three years. Genotypes were also classified into five groups based on the performance and determination of the highest discriminating trait that accounted for more significant variability using cluster analysis and principal component analysis (PCA). The measured characteristics were cucurbit chlorotic yellows virus and fungal severity, off-type plant, vine, internode, leaf, petiole, fruit and fruit trail length, leaf width, male flower percentage, fruit color and groove, fruit diameter, fruit fresh weight, fruit dry matter and ash percentage, fruit pH, EC and TSS, fruit yield, and total fruit number. The IR4 and IR5 genotypes showed the highest fruit yield (460.85 and 425.86 kg/plot) and number (108.72 and 84.22 fruit/plant). IR11 had the highest fruit length of 16.60 cm. High broad-sense heritability was associated with all the traits except for cucurbit chlorotic yellows virus and fungal severity, fruit pH, and total fruit yield. Cluster analysis and its comparison of means showed that IR4 and IR5 from the fifth cluster expressed the best agronomic traits and yield potentials in the warm condition. Hence, selection for any trait would favor genotypes in these clusters. The PCA involved fruit dry matter and TSS as the most discriminating trait that accounted for more significant cucumber variability, which should be considered in cucumber improvement programs.
