초록
‘Aram’ is a high-quality, medium-late maturing rice variety adapted to the Gyeongnam province. It was developed through a crossbetween, ‘Yeonghojinmi,’ a good quality cultivar, and ‘Saenuri,’ a disease-resistant cultivar, in 2016. Anther culture was used for developing‘Aram’. Its average heading date was August 16, which is 2 days later than that of the check cultivar, ‘Nampyeong’. The culm length of‘Aram’ was 82.3 cm, and it had 17 panicles per hill. The ratio of ripened grain was 85%, which was 3% higher than that of ‘Nampyeong’. ‘Aram’ shows resistance to bacterial blight and rice stripe virus and moderate resistance to bakanae disease. However, it is susceptible tothe K3a race of bacterial blight, other viral diseases, and plant-hoppers. ‘Aram’ has strong resistance to viviparous germination (4.9%) beforeharvest, and it shows strong resistance against field lodging. ‘Aram’ has a milling ratio of 74.6%; in addition, it has a high head-rice ratioand Toyo value. In the sensory test of cooked rice, ‘Aram’ had better scores for grain appearance, texture, and other items, compared tothat for the check cultivar, ‘Nampyeong’. Therefore, ‘Aram’ could be used as a raw material for brand rice in Gyeongnam province becauseof its improved production stability and high quality (Registration No. 9628).
