Large and small starch granules were isolated and characterized from kernels of Hiproly barley. Average size of large granules were $28-30{\mu}m$ and that of small granules were $6{\mu}m$. The small granules consist of 95% of total starch granules. Large granules contained more amylose than small granules. Distribution of isoamylase-debranched starch components, X-ray diffraction patterns, gelatinization characteristics by differential scanning calorimetry, and starch-granule susceptibility to acid were investigated. Large granules contained more long B chains of amylopectin and had the lower ratios of Fr. III to Fr. II , which represent one of the structural characteristics of amylopectin, than those of small granules. Small granules had higher conclusion temperature and smaller heat of gelatinization than those of large granules by D.S.C.. Both granules had A-type pattern of X-ray diffractopgrams, but hydrolysis of granules with acid showed different A-type patterns between large and small granules.

Four near-isogenic lines of growth habit derived from the breeders' seeds of Oweolbori and Jogangbori were obtained, respectively. From the analysis of pedigree charts, the genes for the pertinent growth habit in Oweolbori and Jogangbori seemed to be derived from the Milyang 6 and Hiproly, or Joshushirohadaka, respectively. The spring habit grades of the isogenic lines were classified: Oweolbori #1 and #2, Jogangbori #1 and #2 as I : Oweolbori #3 and #4, Jogangbori #3 and #4 as III, respectively. The spring habit of Oweolbori #1 and #2 might be controlled by one pair of recessive gene, shsh. The photoperiodic response, earliness in a narrow sense, and ratio of heading retardation significantly different in the isogenic lines with the same genetic backgrounds. The heading mature time differed in the isogenic lines sown in fall.
