“…The present study identified potential materials to be incorporated in genetic improvement of mango for both monoembryonic and polyembryonic types. In fact, elite individuals from each of the three clusters are potential parents for hybridization and improvement of mango varieties [51,52]. Our results provide sound basis for selection of genetic resources to gain better understanding in the genetic architecture of important traits including edible quality, fruit weight, soluble sugar contents, and pulp weight.…”

Collection, characterization and utilization of genetic resources are crucial for developing varieties to meet current and future needs. Although mango is an economically important fruit tree, its genetic resources are still undocumented and are threatened in their natural habits. In this study, the variability of 452 mango accessions from three regions in China (Nujiang, Lancang river and Honghe) was assessed using 41 descriptors including qualitative and quantitative traits, with the aim to identify mango accessions with excellent agronomic and quality traits. To this end, descriptive and multivariate analyses were performed. Based on Shannon–Weaver diversity index, qualitative traits including pericarp color, fruit aroma, flesh color, and fruit flavor recorded the highest variability in the germplasm. Fruit related traits including pulp weight, peel weight, and fruit weight were the most diverse traits in the germplasm with a high coefficient of variation (CV > 40%). Significant differences (MANOVA test, p < 0.000) were observed among the three regions for most of the quantitative traits. Biologically significant and positive correlations were found among agronomically important traits such as fruit weight and pulp weight, fruit weight and edible rate. The hierarchical cluster analysis revealed tree clusters, indicating a low diversity in the germplasm. The majority of the descriptors contributed to the differentiation of the accessions. Accessions with good fruits quality (high fruit weight, pulp weight, and edible rate) were found in Cluster 2. Accessions in this cluster could be used for fruit quality improvement in mango breeding programs. Our study sheds light on the diversity of a large collection of natural mango population in China and provides relevant information for efficient conservation and harnessing of mango genetic resources.

“…Similarly, Kaur et al (2014) reported that climatic condition of Punjab also enhanced the development of light yellow colors on ripening. A mango breeding program was conducted at the Central Institute for Subtropical Horticulture, Lucknow (1992), to obtained regular bearing high yielding colored cultivars for domestic as well as export markets (Negi et al, 2000). In this program, a Hybrid was developed by crossing "Dashehari" X "Chausa" allias, this Hybrid "CISH-M-2" had average fruit weight of 220g and having TSS of 23.00 0 B.…”

Mango cultivars like Langra, Dashehai and Chausa are famous for their unique test and high TSS content. Due to their size and bearing potential, these verities are not only popular in Jharkhand but also in demand throughout the India. To mitigate the growing demand of colored mango variety in local as well as national market, a varietal improvement program has been conducted at ICAR-RCER, Research Centre, Ranchi, India. During this study, mango cultivars Langra, Dashehai and Chausa have been used as female plant while pollen grain of Swarnarekhan, Kesar and Vanraj were used as male parent in diallel crosses. Results of study revealed that Hybrids obtained by the crossing of Langra x Vanraj (Hybrid 1) and Langra x Kesar (Hybrid -2) are superior in term of their fruit tree character, bearing habit and fruit quality. Among various obtained Hybrids, Hybrid -2 (Langra x Kesar) have highest TSS (20.5 0 B) and total sugar content (12.37 %) with yellow color, this was followed by Hybrid -I (19.5 0 B) and Hybrid-3 (11.5 0 B). In terms of regular bearing, Hybrid -1 was the most promising one and it was followed by the Hybrid-3 (Chausa x Vanraj). Further, with respect to yield potential, Hybrid -2 showed superiority over the rest two Hybrids and 7 year old plant gave 12.5 kg fruit/year.

“…There are bright prospects of building up a flourishing trade for the export of this fruit. Although mangoes are exported to nearly 20 countries, whereas its products are exported to over 40 countries [8] and still there are many doors pending to be opened to flourish trading for export of D DAVID PUBLISHING this fruit. In the state of Odisha, mango occupies 14.23 thousand ha with production of 103.73 thousand metric tonne and productivity is 7.3 metric tonne/ha [7].…”

A study was carried out among the local mango types in Odisha to explore their genetic variations for further utilization in crop improvement, as the genetic diversity serves as a way for the population to adopt the changing edapho-climatic condition. From 17 districts of Odisha, a total of 548 seedling trees were observed, but only 30 mango elites were selected on the basis of organoleptic test for taste, flavor and aroma. Different physico-chemical characters, like fruit size, shape, colour, flavour, aroma and other characteristics, varied widely among these genotypes. The results of the study with respect to 30 numbers of local mango genotypes revealed that the maximum individual fruit weight (510 g) and pulp percentage (78.4%) was recorded in Kali. The other desirable traits of the minimum stone percentage (5.9%) and the maximum pulp to stone ratio (12.5:1) was observed in Nakei. The minimum peel percentage (10.0%) and the maximum total soluble solid (TSS) percentage (26%) was recorded in the fruits of Mitha and Lori, respectively. Attractive fruit skin colour was observed in the genotypes Nakei and Belua (yellowish), followed by Sundari (yellow with orange tinge) and Kadalia (greenish yellow). But in case of check mango cultivars Amrapali and Mallika, desirable traits, like the maximum TSS, pulp percentage, pulp to stone ratio and the minimum stone percentage was exhibited by Amrapali, whereas Mallika had the maximum fruit weight. The shape and skin colour are neither attractive nor preferred in both the commercial cultivars, so above cited eye catchy traits can be incorporated into these two superior mango genotypes from the local genotypes to meet the market demand and export potential.
