“…The period 1980 to 2015 has been the warmest period of the 1400-year duration; global temperature has risen to about 0.85°C during this period. One of the consequences of climate change will be reduced crop yield and it is believed to be the major risk in the realm of agriculture (Sonia et al, 2019). Among all the crops, the production of the wheat will be highly reduced due to rise in temperature.…”

Assessment of variability and traits association in crop help to enhance selection efficiency. Therefore, the present investigation entitled “Variability, Correlation and Path Coefficient Analysis for Agro-morphological Traits in Wheat Genotypes (Triticum aestivum L.) under Normal and Heat Stress Conditions” was carried out during winterseason of 2019/2020 at Institute of Agriculture and Animal Science (IAAS), Bhairahawa, Nepal to identify traits that highly contribute to grain yield and suitable for its further improvement. The experiment was laid out following alpha lattice design with two replications. The twentygenotypes of wheat was sown in two different environments viz., irrigated and heat stress in November 29, 2019 and December 25, 2019 respectively. It was found that under normal condition, moderate GCV and PCV were recorded in SW, TGW, NGPS, and WGPS. Under heat stress condition, high GCV and PCV were observed in GY. High heritability and high GAM was observed in TGW & GY, NGPS, WGPS, TGW under normal and heat stress condition respectively. Under normal condition SW exhibited positive correlation and high positive direct effect on GY at genetic level and WGPS at phenotypic level. And under heat stress condition SW exhibited positive correlation and high positive direct effect on GY. Whereas, at phenotypic level, WGPS and PH exhibited high positive direct effect on grain yield. Hence it is clear that spike weight and weight of grains per spike are important traits for grain yield improvement. Int. J. Appl. Sci. Biotechnol. Vol 9(1): 65-74

“…Climate change mediated rainfall sequences are predicted to cause heavy rainfall but less occurring frequency will change the wheat productivity; but a prediction by Hadley Centre Model (HadCM3) represents common decrease in yearly precipitation in Oklahoma and these may not subject to lower wheat yield (Tataw et al, 2016;Zhang and Nearing, 2005). In Khyber Pakhtunkhwa (KP) Province, Pakistan they used Econometric diagnostic tests to verify the model stability and LM test was encompassed to detect the serial correlation which concludes that temperature and precipitation have inverse association with wheat production while humidity is positively associated (Sonia et al, 2019).…”

Wheat is a crop consist of 15 grams of protein, 10.6 grams of dietary fiber, 71.2 grams of carbohydrates, and 38 milligrams of calcium. In the context of Nepal, it lies in the 3rd position as a cultivation crop. In 2020, wheat production for Nepal was 2,210 thousand tonnes. Wheat production in Nepal increased from 193 thousand tonnes in 1971 to 2,210 thousand tonnes in 2020 growing at an average annual rate of 5.73% but due to changes in climatic parameters productivity ratio are affected. Stem prolongation and tiller development were destroyed by minimum temperature in the earlier vegetative phase whereas the maximum temperature in the heading phase hampered wheat grain filling and panicle development. Rainfall decreased wheat yield, LAI (leaf area index), and plant height. Similarly, CO2 concentration and solar radiation have an impact on the yield of wheat also which is given in this article. Further studies are require to overcome the negative aspect of climatic change towards the plant development either from germination to yield period.

“…Every year there is change in rainfall pattern, increase in temperature and CO2 along with decrease in annual precipitation [10]. Due to climate change, major risks are faced by the agriculture sector because of which crop yield is reduced [11]. Higher temperature during anthesis due to climate change adversely affects winter crops.…”

Correlation coefficient and path analysis were computed between yield and yield attributing trait among twenty genotypes of wheat. The research was conducted during winter season of 2020/2021 in the agronomic field of the Institute of Agriculture and Animal Science (IAAS), Bhairahawa, Nepal to identify the traits which influence the positive and negative relation to grain yield. Twenty genotypes of wheat were sown on 24th December 2020 on alpha lattice design with two replications. It has been found that under heat stress, DTB, DTH, DTM, CLC, PH, NGPS show a non-significant positive correlation with GY. Similarly ET shows a highly significant positive correlation to GY. However, SL, SW, TKW have a non-significant negative correlation with GY. In path analysis, DTM and ET have a positive direct effect on GY and DTH, SL, CLC and NGPS have an indirect effect on GY. Hence, the ET and DTM can be used to select wheat genotype for breeding purpose and studies to improve yield of genotypes under heat stress condition.
