崔周鎬,金鎭雨 진주산업대학교 1993 論文集 Vol.32 No.-

The effects of compound fertilizers on the yield and growth characters of the paddy rice variety, Man-kum, were studied. The length of culm and panicle, the weights of 1000 grains, empty grains and rice screenings, and the quantity of protein and total nitrogen content increased significantly. The percentage of ripeness and hulled or unhulled rice decreased the overall acceptability of fertilizers.

In this study, 45 combinations of F_(1) and F_(2) through 10-variety diallel cross population of cotton (Gossypium spp) were obtained at the experimental field in JinJu National University from April, 2000 to Dec. 2002. The results on the genetic analysis of 45 combinations were as follow: The high significance was observed from the genetic variance analysis of all the examined characters. In the analysis of additive effect and genetic effect, all the examined characters showed a high significance except days to maturity and number of fruiting branches. Based on the Vr-Wr graphical analysis, all of the examined characters were assumed to be inherited over dominance except days to maturity, number of flowering, number of fruiting branches, boll length, boll width, fresh weight and root weight. In the component of genetic variance analysis, dominant effects were higher than additive effects for days to flowering, days to maturity number of flowering, plant height, length of stem internode, number of fruiting branches, stalk diameter, fresh weigh and root weight while for boll length and boll width, additive effects were higher than dominant effects. The higher heritability was observed in the progeny of F_(1) than in those of F_(2) and the heritability of F_(1) was 0.54 in all of the examined characters except stalk diameter
