The germplasms of naked barley evaluated for starch content were 137 crossing blacks and progeny lines obtained from the breeding program of the Wheat and Barley Research Institute, 540 Tabdong Kwonsungu Suwon, in the 1988/1989 season. Starch content was distributed between 49.15 and 62.50% with a mean of 57.20%. It was high in the bred lines and the Uz type lines than the imported, uz type or lax type ones. The range observed for seed coat weight was 1.12-3.02mg and the mean seed coat weight was 1.88mg. The seed coat weight ratio to kernel weight was measured between 4.0 and 8.7% with a mean of 6.5%. The varieties differ greatly in the characteristics depending on the plant type and origin of germplasms. The variation observed with protein content ranged from 9.60 to. 15.90% while the average was 12.86%. Starch content was negative relationships with kernel weight, seed coat weight, seed coat weight ratio., kernel width, kernel thickness and protein content, and starch content was higher in smaller kernels within a variety. The weight and weight ratio. of seed coat were positively correlated with the width, thick-ness of kernels, whilst they were negatively correlated with starch content. The heritability of starch content was 30.0%.
