Hwangeumnodeul is a new japonica rice cultivar developed from a cross between Milyang165 and HR15151-B-21-3 at Honam Agricultural Research Institute (HARI), NICS, RDA, in 2007. This cultivar has short grains and about 139 days of growth duration from direct seeding to harvesting in the southern plain areas. Culm length of this cultivar is 78 cm and the number of spikelet per panicle is similar to that of the check cultivar, Nampyeongbyeo, while filled grain rate is lower than the check variety. This cultivar is moderately resistant to leaf blast, bacterial blight pathogens of K1, K2 and K3 and stripe virus but susceptible to major virus diseases and insect pests. Milled kernel of Hwanggeumnodeul is translucent with non-glutinous endosperm. This cultivar has about 5.7% and 18.6% of protein and amylose contents, respectively. Palatability of cooked rice of Hwanggeumnodeul is similar to Nampyeongbyeo. Its milling recovery and head rice were 75.6% and 90.0%, respectively. Hwanggeumnodeul yielded 5.69 and 5.61 MT/ha in milled rice at the under wet-direct and dry-direct seeding conditions, respectively which are 17% and 12% higher than the check variety, Juanbyeo. It yielded 5.86 MT/ha, 8% higher than Nampyeongbyeo at the standard fertilizer level of the ordinary transplanting cultivation. “wanggeumnodeul”would be adaptable for ordinary transplanting as well as direct seeding in the southern plain including Chungcheong province.

“ongjin2”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 “ongjin2”is translucent with non-glutinous endosperm. It has about 19.3% of amylose content and better palatability of cooked rice compared with “ampyeongbyeo” 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. “ongjin2”yields about 5.71 and 5.74 MT/ha under the wet direct seeding and the transplanting at standard fertilizer level. “ongjin2”would be adaptable for the southern plain area of Korea.
