“…High degree of additive gene effect implies less control by environment on the trait. Similar to the result obtained were reported by Chakraborty et al, (2013) in bitter gourd, Sharma and Sengupta (2013), Khan et al, (2016) in bottle gourd and Karthik et al, (2017) in ridge gourd.…”

Ridge gourd (Luffa acutangula (L.) Roxb.) is the fruit of a sub-tropical vine that belongs to the Cucurbitaceae family and is native to central and eastern Asia, including the Indian subcontinent. In this study, four crosses of ridge gourd were evaluated in the F2 generation and two crosses were advanced to F3 segregating generation for investigating the variability, heritability and genetic advance of ridge gourd. Among the crosses studied, L3xT1(Virudhunagar Local x Periyakottai Local) and L3xT2(Virudhunagar Local x Alathur Local), exhibited superior per se performance in both F2 and F3 generations for almost all the yield contributing characters. The F2 and F3 populations of cross L3xT1 and L3xT2 showed moderate to high PCV, GCV coupled with high heritability estimates and high genetic advance as percentage of mean for node to first male flower, node to first female flower, sex ratio, number of fruits per vine, fruit length, fruit diameter, rind thickness, flesh thickness, number of seeds per fruit and fruit yield per vine.

“…Vine length showed highest positive indirect effect on total yield per plant through number of fruit per vine, fruit equatorial diameter and 100 seed weight. The similar results were also reported by Khan et al, (2016) in snake gourd. Days to first female flower appearance showed negative indirect effect towards total yield per plant through number of fruit per vine (Srikanth et al, 2015), 100 seed weight and fruit equatorial diameter.…”

“…Number of node at first female flower appearance exerted the highest negative indirect effect on yield per plant through ascorbic acid content (-0.5249) followed by days to first harvest (-0.4903 Number of fruit per vine exerted the highest positive direct effect on total yield per plant (Khan et al, 2016) in snake gourd followed by sex ratio, fruit polar diameter and days to first harvest (Srikanth et al, 2015) in pumpkin, fruits equatorial diameter, seed weight per fruit, node number for first female flower appearance and flesh thickness. Akter et al, (2013) and Naik et al, (2015) in pumpkin also revealed that number of fruits per plant had the maximum direct effect on yield per plant.…”

“…For pumpkin, few studies used correlation path analysis. Khan et al (2017) identified the fruit weight as one of the traits that allows the selection of productive genotypes of snake gourd (Trichosamthes cucumerina, var. anguina).…”

“…Yield is a complex character that is greatly influenced by several associated traits, which are controlled by many genes and whose expression is strongly influenced by the environment (Mustafa et al, 2018). In plant breeding, sufficient genetic variation is a condition for the selection of agronomically desirable genotypes, especially of traits highly correlated with each other and with yield (Khan et al, 2017). Thus, in the selection process, it is important to knowledge about the relationships between characteristics of interest, which can be done by determining the correlations between phenotypic characters (Santos et al, 2018).…”

Traits related to fruit yield and physical and chemical fruit quality are being evaluated by Embrapa pumpkin breeding program. Path and Pearson's correlation analysis are necessary to allow the knowledge of the relation between the variables of interest for this program. The objective of the present study was to determine the genetic correlations between yield- and sensorial and nutritional quality attributes-associated variables in pumpkin progenies to support the selection process. Twelve genotypes were evaluated for 10 yield-related traits, and 8 sensory and nutritional quality traits of fruit, including the commercial cultivar Jacarezinho. A path analysis considered the fruit weight (FrW) was as basic variable and the others as explanatory. The FrW had 98% of its total variation available in a function of the explanatory variables. The highest variations were observed in the fruit-shape related traits. In addition, the variables internal median cavity diameter (IDmed), equatorial pulp thickness (EPT), apical pulp thickness (APT), and smallest fruit diameter (Dsm) are indicated for a direct selection of progenies targeting a higher FrW. The correlation analysis highlighted that color-related variables have the possibility of indirect selection aiming to increase total carotenoid content (TCC) and β-carotene content (β-car). The evaluated progenies showed notable soluble solids content (SSC), TCC and β-car contents compared to the commercial cultivar. Furthermore, the contribution of β-car to TCC is at least 50% higher in these progenies than in 'Jacarezinho' pumpkin.
