China Title: Genetic relationships among Cucurbita pepo ornamental gourds based on EST-SSR markers Abstract: The ornamental gourd Cucurbita pepo L. is a ubiquitous crop native to North America, exhibiting highly diverse fruit characteristics. Studying the genetic diversity of ornamental gourds can help identify and evaluate the curated germplasm resources, understand the phylogenetic relationships among them, and highlight ways in which the germplasm resources can be used to address gaps in the understanding. In this study, a set of 85 of 323 previously identified polymorphic expressed sequence tag-simple sequence repeat (EST-SSR) genetic markers were selected to evaluate the genetic relationships among 47 C. pepo accessions and one C. foetidissima accession. This collection consisted of accessions from the subspecies pepo, texana, and the hybrid texana × pepo. Our analyses yielded a total of 271 alleles, with an average of 3.2 alleles per genetic locus. The dendrogram construction, principal coordinate analyses, and genetic value calculation revealed several robust subclusters in the texana subspecies accessions. From these results, we propose five new distinct morphotypes based on our construction of a concise SSR fingerprint. Moreover, our study confirms that the fruit shape similarity among accessions is a fair reflection of genetic relatedness.

The leaf chlorophyll status is a key determinant for a high rate of photosynthesis under stress. The present experiments included 238 genotypes in 2016-2017 and 321 genotypes in 2017-2018 under optimum and under heat stress conditions. Subsequently, a set of 100 genotypes selected on basis of the heat susceptibility index was evaluated in 2018-2019 under heat stress conditions to study the relationship between important physiological traits and yield under stress. A significant correlation of soil plant analysis development (SPAD) value of the two upper leaves with stay-green trait and grain yield indicates the importance of chlorophyll content, both in flag and penultimate leaf, in maintaining leaf areas under greenness (LAUG) and grain yield under heat stress. The SPAD in the flag and penultimate leaf was responsible for 8.8% and 10.9%, respectively, of the variation in grain yield. For the stay-green trait, 8.4% and 7.2 % of the variation was governed by the SPAD value in the flag and penultimate leaf, respectively. These results suggest that, in addition to the flag leaf, the chlorophyll status of the penultimate leaf can be an important criterion for the selection of superior wheat genotypes under heat stress. The genotypes SW-139; SW 108; DWR-F8-35-9-1; NHP-F8-130; DWR-F8-3-1 that maintained a high chlorophyll content in the flag and penultimate leaf can be used further in breeding programmes addressing heat resistance in wheat.

The cultivars were developed using waxy wheat material from Nebraska, the United States of America. The mean yield of Eldija and Sarta at five locations over three testing years was 7.56 and 7.21 t/ha or 79.63 and 75.95%, respectively, compared to the yield of the standard cultivars. Eldija and Sarta should be grown under high input conditions due to the relatively low resistance to leaf spot diseases and Fusarium head blight and medium tolerance to lodging. An amylose content of 0.68% and 0.36% of Eldija and Sarta, respectively, a very low falling number (about 60 s), a lower flour yield and higher water absorption compared to common wheat and the reaction to iodine staining (brown colour) characterised the new cultivars as fully waxy wheats. These cultivars are intended for the potential demand from commercial companies for special use in the food industry.

Numerous chemical compounds have been isolated from pomegranate seeds, juice, and peels, which have beneficial effects on human health. This study aimed to perform the physicochemical and morphological properties of twenty-four pomegranate genotypes from various provinces of Iran. Fifteen fruits of each cultivar are collected at harvest maturity in the normal ripening period for the pomegranate from the Iranian pomegranate genetic collection in Yazd, Iran. Five fruits were randomly harvested from each of four orientations of the tree, and were immediately taken to the laboratory for analysis. Three replicates were maintained for each analysis. The results indicated the highest levels of anthocyanin was observed in S783 and R633, while polyphenols in Q529, the antioxidant capacity in N755 and the total soluble solids levels in R633 and the total acidity levels were found in K477 and E336. On the other hand, the fruit weight (in S948), fruit diameter (in SH1738), crown diameter (in R533), total weight of the seeds (in S948), peel thickness (in S716), peel colour (in S948), and red juice (in S783) are significantly affected by the genotype. At a similarity of 50%, the genotypes were divided into nine sub-clusters including A, B, C, D, E, F, G, H and I. These identified genotypes can be rolled out in future breeding programmes.

China Title: Characterization of a naturally occurring early-flowering rice mutant resulting from a novel variation in the Ghd7 locus Abstract: Rice is one of the main staple food crops and is consumed by more than half of the global population. Optimizing the flowering time may help to maximize grain production. In this study, we characterized a rice mutant, Zixiangnuo early-flowering mutant (ZXN-E). Compared with the wild-type variety, Zixiangnuo (ZXN), the mutant plants flowered earlier, were shorter and produced smaller panicles. Bulked segregant analysis revealed a 7-bp deletion in the first exon of the Grain number, plant height, and heading date 7 (Ghd7) locus. The allele with the 7-bp deletion was not detected in the rice varieties included in the 3 000 Rice Genomes Project. Thus, the 7-bp deletion identified in the naturally occurring mutant ZXN-E is a novel variation. Our findings suggest that ZXN-E may be a useful germplasm for breeding new rice varieties.
