Abstract: Maize is the most frequently widely grown crop in the world; one of the major constraints affecting maize production and productivity is the inadequacy of widely adapted, high-yielding, disease- and insect-resistant varieties. The objective of this study was to select widely adapted, stable, high yielder and good agronomic traits hybrid maize varieties for the study area.. The study was conducted at Mechara, Boke, and Doba locations for two years, during 2022-2023 main cropping seasons. Seven-hybrid maize Varieties were examined in six environments under rain-fed conditions using the RCB Design with three replications. Analysis of variance revealed highly significant (p ≤ 0.001) variance due to varieties, environments, and GEI among all traits. days to silking, days to maturity, plant height, Ear height, Number of row per ear, ear length, hundred seed weight and grain yield were highly affected by environment, and varieties, while Days to silking, Number of Kernel per ear, hundred seed weight, Ear length and Grain Yield were mainly affected by GEI variations. AMMI analysis indicated significant genotype, environment and GEI effects; accounting for 6.8%, 47.7% and 8.6%, respectively, to the total variation. IPCA1 and IPCA2 accounted for 84.3% (63.2% and 21.1%) of the G + GE variation for grain yield of the varieties evaluated at six environments. Among testing sites, Three Varieties (BH549, Damote and DK-77) were superior and stable across test environments for grain yield and related traits. Overall, based on mean grain yield, AMMI and GGE biplot, BH549 was the most stable and high-yielding hybrid maize variety.. It can be concluded that this superior hybrid maize variety can be demonstrated and popularized, as well as being important for inclusion in further breeding programs since they may contribute favorable alleles in the synthesis of new varieties and make a great contribution to the food security of the target areas.

Abstract: Xinjiang, also known as Xinjiang Uygur Autonomous Region (XUAR), with an area of over 1.6 million km2 (0.64 million square miles), is the biggest province in China. Xinjiang is notable for its diversity and abundance of lichens. This study reports two lichen taxa newly recorded for China from the Barluk Mountain National Nature Reserve (BMNNR), Xinjiang, China, and provides morphological, anatomical, chemical, and Internal Transcribed Spacer (ITS) based molecular data. The lichen specimens used in this article were collected from (BMNNR) between 2022 and 2024. Two lichen species, Anamylopsora pakistanica and Lepraria rigidula, were discovered during a taxonomical study of the lichens from (BMNNR), Xinjiang, China. Both of these lichen species have never been reported from China before. Here, these are the new records for China. Anamylopsora pakistanica grows on well-lit bare rock surface, and is characterized by its having larger squamules, the margin of squamules is white; Lepraria rigidula grows on mosses attached to rocks, and is characterized by its dense long soredium and has atranorin. Descriptions in detail, comments with similar species, and morphological photographs of these two species are provided. The specimens of these two new records were deposited in the Herbarium of College of Life Sciences and Technology, Xinjiang University (XJU) (XUAR), China. These collections recommend a great potential for discovery of further unreported lichen species in Xinjiang Province.
