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+1.5℃(T2), T1+3.0℃(T3) and T1+5.0℃(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 LITERATURE REVIEW 5 Climate change 5 Abiotic stress in plants 6 Analysis of variance (ANOVA) 7 Soybean and Mungbean 7 MATERIALS AND METHODS 10 Plant materials 10 Temperature treatments 10 Phenotyping of agronomic traits 11 Statistical analysis 13 RESULTS AND DISCUSSION 14 Interaction of temperature and genotype in soybean 14 Effect on traits in soybean by genotype and temperature 16 Significant of temperature on traits by genotypes in soybean 19 Interaction of temperature and genotype in mungbean 26 Effect on traits in mungbean by genotype and temperature 28 Significant of temperature on traits in mungbean 30 REFERENCE 36 ABSTRACT IN KOREAN 40Maste
