A set of 21 crosses of Fl generation by diallel crosses from seven parent silkworm, Bombyx mori L. were used as materials to estimate genetic parameters such as gene action and combining ability. Experiments were conducted in 1985, and three characters, which are weight of cocoon, weight of cocoon layer and ratio of cocoon layer, were observed. The data were analyzed for each character by Jinks', Hayman's and Griffing's methods. The result obtained are summarized as folllows: 1. In Vr-Wr graphical analyses, weight of cocoon was found to be inherited in over dominance, and weight of cocoon layer and ratio of cocoon layer were observed as partial dominance. 2. Estimate of additive component of variance(D) was greater than those of dominance component of variance(H) for weight of cocoon layer and ratio of cocoon layer, and positive values of F were observed for all characters. 3. Mean squares of general combining ability were higher than those of specific combining ability. 4. Variety Jam 107 was expressed as the highest GCA effects for three characters, and high SCA effects for all characters were observed in combinations of Jam 113 X Jung 14 and Jam 107 X jung 14.

The study was conducted to get genetic information about quantative characters of F2's in barley through diallel crosses using four six-rowed barley and two-rowed barley. The results obtained were summarized as follows. Additive-dominant, dominant, maternal, and reciprocal effect were observed in culm length, tiller number, spike length, number of grains per spike, and 1000 grain weight. Based on the Vr-Wr graphical analysis, culm length, tiller number, spike length, number of grains per spike, and 1000 grain weight were found to inherit incomplete dominance. Dominant effects were higher than additive effects in culm length, tiller number, and 1000 grain weight, while additive effects were significant in spike length and number of grains per spike. The narrow- sense heritability showed high value as 0.6906 for number of grains per spike and as 0.0682 for spike length. The positive correlations were showed among characters such as between culm length and tiller number, culm length and spike length, culm length and 1000 grain weight, and spike length and 1000 grain weight.
