Abstract

Wheat is a major winter season crop contributing 5.87% shares in the national AGDP. Less precipitation and inadequate irrigation infrastructure result in the loss of 0.65 million metric tons of wheat annually, but the stress-tolerant varieties are limited. The study aimed to identify the most stable and high-yielding performance genotypes for different conditions. The field experiment was conducted in Rupandehi and Nawalparasi under three conditions: irrigation, Heat Stress and drought sowing on 17th November 2024 by using Randomised Complete Block Design (RCBD) having three replications with 20 wheat varieties, including 17 different genotypes and 3 checks. Yield attributing data were entered in MS-Excel and analysed using META and GEA-R to determine the yield adaptability under irrigated and abiotic stress conditions. The present study concluded that NL 1501, NL 1627, and Gautam were the most stable across irrigated, heat-tolerant, and drought environments based on GGE Biplot Models. In contrast, NL 1492 was specifically adapted to Rupandehi irrigated and Nawalparasi irrigated, NL 1376 performed best at Rupandehi heat stress and Nawalparasi heat-stress conditions, and NL 1626 was adapted to Nawalparasi drought and Rupandehi drought environments. This result will be helpful for breeders and researchers to comprehensively understand the agro-morphological characters as well as the stability of Wheat genotypes under abiotic stress and irrigated condition at western region of Nepal.
