초록
'해담쌀'은 남부평야지 조기재배 적응 줄무늬잎마름병 저항성 조생종 품종을 육성하고자 YR25869(YR21247-B-B-B-49-1/SasanishikiBL4//Koshihikari)와 YR25868(Unkwang//YR21247-B-B-B-49-1/ Sasanishiki BL4)의 복교잡으로 육성되었다. 줄무늬잎마름병 저항성 유전자를 도입하기 위해 3원교잡 및 복교잡 F1세대에서 저항성 연관마커 RM6897로 선발하였다. F2세대에서 F5세대까지 집단육종법으로 동계온실을 이용한 세대단축 시스템으로 빠르게 고정된 계통을 육성하였다. 2011~2012년 동안 생산력검정시험을 거쳐 '밀양275호'로 명명하였다. 2012~2014년 3년간 지역적응성 시험 조기재배에서 완전미율과 밥맛이 우수한 특성을 가지고 있어 '해담쌀'로 명명되었다. '해담쌀'은 간장이 67 cm로 '조평'보다 5 cm 작은 단간이며, 수당립수는 적고 수수가 약간 많은 초형을 가지고 있다. 이 품종의 내병성은 흰잎마름병, 줄무늬잎마름병에 저항성이며, 잎도열병에 강한 편이다. 수량은 조기재배 지역적응성 시험에서 5.48 MT/ha으로 대비 품종보다 수량이 높았다. 금후 이 계통은 남부지역의 조기재배용으로 밥맛이 우수한 쌀 생산을 위한 품종으로 보급될 것으로 기대된다.
'Haedamssal' is an early maturing and rice stripe virus disease-resistant cultivar adaptable for early-transplanting cultivation that was developed by the rice breeding team of the Department of Southern Crop, NICS, RDA, in 2014. This cultivar was derived from the cross YR25869 (YR21247-B-B-B-49-1/Sasanishiki BL4//Koshihikari) and YR25868 (Unkwang//YR21247-B-B-B-49-1/Sasanishiki BL4) made in the 2005/2006 winter season and was advanced to the F5 generation by a bulk breeding method using rapid generation advance. To incorporate rice stripe virus resistance, marker-assisted selection on the RSV gene was conducted in 3-way and 6-way cross F1 generation using the tightly linked marker RM6897. From testing in the replicated yield trial in 2011, a promising line YR26258-B-B-B-33-3 was selected and it was designated as 'Milyang276'. A local adaptability test of 'Milyang276' was performed at three locations from 2012 to 2014 and it was named as 'Haedamssal', which was a good eating quality variety. The culm length was 67 cm in yield trials, which was 4 cm shorter than 'Jopyeong'. The number of spikelets per panicle was lower than 'Jopyeong', whereas the number of tillers per hill was higher. This variety was resistant to RSV disease, bacterial blight, and leaf blast disease. The milled rice yield of 'Haedamssal' was 5.48 MT per ha at the early transplanting in the local adaptability test. 'Haedamssal' is well adapted to early transplanting cultivation in the southern plain area (Registration No. 6811).
