Solanum macrocarpon L is a fruit and leaf vegetable in sub-Sahara Africa. The genetic diversity of the crop remains largely unexploited consequently there is a dearth of genetic information on agronomic and fruit quality traits. Agronomic and fruit quality variability and association among traits were evaluated. Twenty – six accessions were grown in a randomized complete block design with three replications. Measurements taken on agronomic and fruit quality traits were subjected to a combined analysis of variance, Principal Component Analysis and grouping using Unweighted Pair Group Method Arithmetic Average using option Ward’s. There were significant differences (P≤0.05) among the accessions for all the traits, while Genotype by Year Interaction (GYI) showed insignificant effects for most traits except plant height at flowering and maturity and seed yield. High broad sense heritability suggested the preponderance of both additive and non-additive genetic action for agronomic and fruit quality traits. The percentage contribution of agronomic traits toward the genetic diversity was maximum in plant height at flowering and plant height at maturity. Positive correlation coefficients was recorded between days to 50% flowering and fruit infructescence/plant (r = 0.45, P≤ 0.05). Dendogram analysis revealed three distinct groups with overlap of traits and no relationship between geographic location and phenotypic diversity. Hybridization among MM 268, MM 10256, MM 150 and MM 10161 may bring together gene constellations for earliness, fruit yield and delayed time to fruit browning. Superior genotypes are recommended for use in hybridization schemes for variety development and the subsequent molecular characterizationBangladesh J. Agril. Res. 43(1): 25-38, March 2018

Abstract Apricot (Prunus armeniaca L.) is a world-wide highly appreciated fruit, with its attractive colour, soft texture and typical flavour. In the current investigation, 68 apricot accessions collected from Jammu and Kashmir, India were analysed to determine the measure of variation using 12 qualitative and 16 quantitative traits with an aim to identify superior apricot accessions with excellent fruit quality traits. High phenotypic variability was observed among the studied apricot accessions with significant differences among most of the qualitative and quantitative traits. Fruit-related characteristics including fruit weight, fruit length, fruit ratio, fruit firmness, fruit shape, fruit suture, stone weight, kernel weight and stone shape were the most diverse with a high coefficient of variation (>30%). One way analysis of variance showed significant differences (P < 0.0001) among all the quantitative traits. Significant positive and negative correlations were observed between all the agronomically important fruit quality traits. The principal component analysis (PCA) revealed that 75.34% of the variability was defined by the first eight components. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram, based on all traits measured grouped the accessions into two main clusters with several sub-clusters. Both UPGMA dendrogram and PCA scatter plot formed a cluster of 14 accessions, having the highest values regarding most important fruit quality traits such as fruit weight, fruit length and width, fruit ratio, stone weight and kernel weight can be treated as potentially superior accessions. These accessions can be used directly for cultivation and in future apricot breeding programmes. The present findings are promising for genetic resource management, cultivar improvement and commercial applications of apricot in Jammu and Kashmir, India.

AbstractFruit quality traits play a significant role in consumer preferences and consumption in blueberry (Vaccinium corymbosum L). The objectives of this study were to construct a high-density linkage map and to identify the underlying genetic basis of fruit quality traits in blueberry. A total of 287 F1 individuals derived from a cross between two southern highbush blueberry cultivars, ‘Reveille’ and ‘Arlen’, were phenotyped over three years (2016–2018) for fruit quality-related traits, including titratable acidity, pH, total soluble solids, and fruit weight. A high-density linkage map was constructed using 17k single nucleotide polymorphisms markers. The linkage map spanned a total of 1397 cM with an average inter-loci distance of 0.08 cM. The quantitative trait loci interval mapping based on the hidden Markov model identified 18 loci for fruit quality traits, including seven loci for fruit weight, three loci for titratable acidity, five loci for pH, and three loci for total soluble solids. Ten of these loci were detected in more than one year. These loci explained phenotypic variance ranging from 7 to 28% for titratable acidity and total soluble solid, and 8–13% for pH. However, the loci identified for fruit weight did not explain more than 10% of the phenotypic variance. We also reported the association between fruit quality traits and metabolites detected by Proton nuclear magnetic resonance analysis directly responsible for these fruit quality traits. Organic acids, citric acid, and quinic acid were significantly (P < 0.05) and positively correlated with titratable acidity. Sugar molecules showed a strong and positive correlation with total soluble solids. Overall, the study dissected the genetic basis of fruit quality traits and established an association between these fruit quality traits and metabolites.
