It causes global warming which is predicted to have a negative effect on plant growth generally and crop yield due to the damaging effect of high temperatures on plant development.
In this study, we conducted to investigate the response of phenotype of agronomic traits on high temperature in soybean [Glycine max] and mungbean [Vigna radiata] and finally to find the breeding material adaptive to high-temperature stress. We used nine soybean genotypes and two mungbean genotypes as planting materials. It was grown in four different temperature level plastic houses (normal field condition without plastic cover as the control (T1), T1+1.5β(T2), T1+3.0β(T3) and T1+5.0β(T4)) to evaluate physiological response to high-temperature stress. Growth type traits such as plant height and the number of branches increased up to T3 treatment and decreased from T3 treatment in soybean. Flowering was faster with higher temperature and yield components like the number of pods and the number of seeds per pod continuously increased with increasing temperature. SS0404-T5-76 is one of the nine genotype we used, which was very highly significant on major agronomic traits at high temperature and was the increased production with increasing temperature. As a result, it is a promising breeding material to adaptive on high-temperature stress. Plant height and the number of pods consistently increased with increasing temperature in Sunhwanogdu and Gyunggijaerae and yield component like the number of pods and number of seed per pods also increased on high temperature in mungbean. Sunhwanogdu had a much pods number, and it had adaptability of high temperature than Gyunggijaerae.INTRODUCTION 1
