초록
“Dongjin2” is a new japonica rice cultivar developed from the cross between Milyang165 with short culm and lodging resistance and F1 plant of Iksan438, HR14018-B-1-1 and Iksan435 with high palatability at Honam Agricultural Research Institute (HARI), NICS, RDA in 2005. This cultivar has short grain shape and about 143 days growth duration from direct seeding to harvesting under Korean climate condition. The milled kernels of “Dongjin2” is translucent with non-glutinous endosperm. It has about 19.3% of amylose content and better palatability of cooked rice compared with “Nampyeongbyeo”. This cultivar shows high resistance reaction to the bacterial blight pathogene race from K1 to K3, blast and stripe virus but susceptible to insect pests. “Dongjin2” yields about 5.71 and 5.74 MT/ha under the wet direct seeding and the transplanting at standard fertilizer level. “Dongjin2” would be adaptable for the southern plain area of Korea.
