A New Low-Amylose, Good-Quality and Six-rowed Naked Barley Cultivar “Hobanchal”

Abstract

A new naked barley variety, Hobanchal, with low amylose contents, good quality and resistance to stress as BaYMV, lodging and wet damage was developed from a cross between Ginssalbori with resistance to lodging and Suwon 291 with low amylose contents and high yield at National Honam Agricultural Experiment Station in 2002. Its growth habit was winter type(III) with greenish leaves, thick culm and six-rowed spike, and its heading and maturing date were Apr. 20 and May 27, respectively, which were similar to those of check variety, Saechalssalbori. It showed moderate resistance to BaYMV and more tolerant to cold and lodging than check variety. In cooking quality, protein and -glucan contents, water absorption rate and expansibility were superior to check variety and whiteness of pearled grain was better than that of check variety. Its average pearled grain yield in the regional yield trial was 3.46 MT/ha at double cropping in paddy which was slightly higher (2%) than that of check variety. The adaptable area of Hobanchal is warm regions where is more than 7oC (minimum average temperature on Jan.).
