“…The significance of the H for the estimation of high TCC and βcar levels in contrasting genotypes is corroborated here by the inverse correlation between the variables H and TCC, β-car and Rat. Martínez-Valdivieso et al (2015) also reported the inverse association between variables that confer pulp color and total carotenoids content as lutein in a study for the physical and chemical characterization of 22 summer squash genotypes. In this case, it is possible to determine that the correlation between variables associated with the color and the contents of this carotenoid would ensure indirect selection in the evaluated genotypes.…”

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.

“…Principal component analysis has been widely used to assess the differences in the phytochemical compositions of fruit varieties (Khan et al ., ; Martínez‐Valdivieso et al ., ; Margraf et al ., ). The results of PCA indicated that the late‐maturing varieties of ‘Dajie’ and ‘Shushanggan’ tended to have higher levels of quercetin‐3‐rutinoside and (+) ‐ catechin and showed higher antioxidant capacities than the early‐maturing varieties of ‘Xiaobai’ and ‘Liguang’.…”

Summary Polyphenol composition and antioxidant capacities of peel and pulp tissues of six apricot varieties were determined. Variations in polyphenol and antioxidant capacity based on variety (early‐maturing varieties and late‐maturing varieties) and harvest maturity (green mature and full mature) were assessed. The results of principal component analysis revealed that (+)‐catechin made the most important contributions to the antioxidant capacities of the pulp. As the (+)‐catechin content in ‘Dajie’ apricot decreased by 36.8% from green mature to full mature, the antioxidant capacities determined by ABTS free radical scavenging assay, DPPH free radical scavenging assay and cupric ion reducing antioxidant capacity assay decreased by 50.0%, 45.2% and 45.8%, respectively. Levels of phenolic compounds in the apricot peels were approximately 2–4 times higher than those of the pulps. Quercetin‐3‐rutinoside may be substantially responsible for the antioxidant capacities of the peels. The late‐maturing varieties tended to have higher levels of phenolic compounds and higher antioxidant capacities than the early‐maturing varieties. The antioxidant capacities in green mature apricots were much higher than those of full mature apricots.

“…The current average yield of the pumpkin, squash and gourd is 13.17 and 23.08 tons/ha at the global and European level, respectively. The crops occupy about 1.8 million ha in the World, of which 0.15 million ha in Europe (WU et al, 2007; BERENJI and SIKORA, 2011; MARTÍNEZ-VALDIVIESO et al, 2015a;MARTINS et al, 2015;FAO, 2018).…”

investigated parameters, and to distinguish those with the most important contribution to the pumpkin variability. The analysis revealed strong correlations among yield per plant, fruit weight and length of the main stem. Carotenoids content and pH also correlated to yield, while the other quality parameters correlated to each other. Defining both first and second principal components, yield per plant and fruit weight were the parameters with the highest contribution to the variability among the assessed pumpkins. Concerning quality parameters, fruit flesh dry weight contributed the most to the variability. Therefore, the strategy for breeding Hokkaido type pumpkins adapted to Serbian environmental conditions should be based on combining irrespectively selected high-yield and high-quality accessions.
