초록
‘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).
Abstract
‘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.
