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....

Heat stress is a major production constraint of wheat in South Asia, particularly in the Gangetic plains of India and Bangladesh. 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...

Two new waxy winter wheat (Triticum aestivum L.) cultivars, Eldija and Sarta, were developed at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry and released in Lithuania in 2021. 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...

Punica granatum L. is one of the oldest known edible fruits. 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...

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...
