A New Malting Barley Variety, “Hojin” with Superior Quality, High Yielding, Early Maturing and BaYMV Resistance

A new malting barley variety, “Hojin” was developed from the cross between ‘Milyang 69’ and ‘Misatogolden’ which have good quality and Barley Yellow Mosaic Virus(BaYMV) resistance, respectively, by barley breeding team of the Yeongnam Agricultural Research Institute (YARI) in 2004. A promising line, YMB 1734-3B-16-2-1-1, was selected in 2001, and was designated as ‘Milyang 117’ It was prominent and had good result from regional yield trials(RYT) for three years from 2002 to 2004 and released as the name of “Hojin”. ‘Hojin’ is resistant to BaYMV and tolerant to lodging in spite of longer culm than check variety, Jinyang. The average maturing time was two days earlier than Jinyang on paddy field in RYT. The number of spikes per square meter and weight of 1,000 grain in Hojin were more and heavier than in Jinyang. However, number of grain per spike was the same in both varieties. The grain and malt quality of Hojin, such as germination energy, germination capacity, water sensitivity in barley grain and filtration speed, Kolbach index, Diastatic power of malt were superior to Jinyang. The yield potential of Hojin was 5.09 MT/ha on field and 4.72 MT/ha on paddy field in RYT. This variety is suitable for double cropping system with rice in the southern part of the Korean Peninsula.
