신간척지에 조기에 벼를 재배하기 위해서는 내염성 품종개발을 필요로 한다. 내염성 벼 개발을 위해 애기장대로부터 클로닝한 NHX1(Na+/H+ antiporter) 유전자를 아그로박테리움을 이용하여 벼에 형질전환하였다. BNHX1 형질전환체 T3 23계통, NHX1 형질전환체 T6 64계통을 선발하고 내염성 유묘검정을 수행하였다. 이 검정을 토대로 염에 대한 저항성을 5개 그룹으로 나누어 염에 대한 생육변화와 무기이온 함유량을 비교분석하였다. 내염성 벼인 인디카 계열의 Pokkali와 형질전환 계통일수록 초기 생육이 좋았고, 특히 염스트레스 초기에 뿌리생장이 염에 약한 계통보다 3~4배 큰 생장변화를 나타냈다. 또한 줄기부위의 양이온(Ca2+, K+, Mg2+ ) 함유량의 변화폭이 크며, Pokkali와 염에 강한 계통의 경우 염처리 시기동안 줄기부위의 Na+ 함유량이 염에 약한 계통보다 2~3배 적은 것을 확인하였다. 이렇게 선발된 내염성 계통은 간척지 적응성 내염성 벼 개발을 위한 중간모본으로 이용하고자 한다.

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.
