  • Estimate of heritabilities, genotypic and phenotypic correlations and path coefficient analysis were performed for the seven characters of barley cultivars (Hordeum vulgare L.). Heritabilities of broad sense for stem length and spike length were 0.923 and 0.907. Kernels per spike, grain yield and 100 grain weight also showed high heritabilities. High genotypic and phenotypic correlations existed between stem length and 100 grain weight. Grain yield showed highly significant phenotypic correlation with spike length, 100 grain weight and kernels per spike. Genotypic correlations between those characters were moderately high. Number of stem had greatest direct effect but the number of spike had a strong negative direct effect upon grain yield. Kernels per spike via number of spike showed greatest indirect effect and the number of stem via number of spike showed strong negative indirect effect upon grain yield.

  • The experimental studies were intended to clarify the effects of leaf yield calculations, and also aimed at estimating the correlations between some characters for the selection of desirable stocks of mulberry trees. The analysis of covariances was the variance components procedures in a replicated trial for the varieties, and also it was used to obtain the genotypic, phenotypic and environmental correlations between the eight characters-branch length, node number, branch diameter, branch number per stock, total branch weight, old branch weight, new shoot and leaf weight, and leaf weight, etc. The results obtained are summarized as follows: Phenotypic, genotypic and environmental covariances are shown in Table 1 and phenotypic correlations, genotypic correlations and environmental correlations are shown in Table 2. Genotypic correlations were slightly higher than the corresponding phenotypic correlations between the characters in the varieties, but the variation in values due to the change of environment appeared between the characters. Genotypic correlations between the leaf yield of mulberry trees and other characters indicated that high leaf yield was genetically correlated with six characters namely branch length, node number, branch number per stock, total branch weight, old branch weight and new shoot weight, etc. It was also observed that lower correlations were appeared between the leaf yield and branch diameter, and branch diameter and other all characters studied in both genotypic and phenotypic correlation coefficients.

  • Fourty lines of F4 progenies of an Adzuki bean cross, Jukdoo (Korean local variety) X Nesumimochi (Japanese variety) were used as the material, and these lines were grown in replicated trials in 1967. Phenotypic, genotypic and environmental covariances among all possible traits of eight character are calculated as shown in table 1. Phenotypic, genotypic and environmental correlations among all possible paris of eight characters were calculated as shown in table 2. In general, genotypic correlations were higher than the corresponding phenotypic corresponding phenotypic correlations. The genotypic correlations between seed yield (grain weight per plot) and oter agronomic characters indicated that seed yield was genetically associated with the character of pod number per plant, and grain number per plant, which is closely correlated with pod number pr plant, are affected more in Adzukl bean yield than the other agronomic characteracters.

  • The studies were intended to clarify the correlations between the characters and the influences upon yield of mulberry trees. The analysis of covariance was used to obtain the genotypic correlations and phenotypic correlations among the eight characters namely branch length, node number, branch diameter, branch number per stock, total branch weight, old branch weight, new shoot and leaf weight, etc., and path-coefficients were calculated by Dewey's method (5). The results obtained are summarized as follows: 1. Genotypic correlations were slightly higher than the corresponding phenotypic correlations between tile characters as shown in Table 1. It could be indicated that hight leaf yield was genetically correlated with almost all characters studied except branch diameter. 2. Leaf yield of mulberry trees was mainly associated with the characters such as node number per branch, total branch weight and old branch weight, etc. 3. Branch length, branch diameter, branch number per stock and new shoot weight had little direct influence upon yield but it had rather considerable indirect in fluence upon yield by increasing the node number and total branch weight per stock. As a result, it can be concluded that total branch weight is primarily determined by branch number per stock and old branch weight, and in turn the leaf yield of mulberry trees is secondary determined by the node number by increasing the branch diameter and length which are positively correlated with branch number per stock and new shoot weight of mulberry trees.

  • Chinese CGMS (Cytoplasmic-Genetic Male Sterility) is being transfered to Korean cultivars which will be used as CGMS maintainers. These maintainer lines along with the Chinese CGMS lines and their maintainer lines were crossed with another group of Korean cultivars which will be used as the fertility restorers, and their yield heterosis were examined. The yield heterosis was calculated as high as 113.0-221.1 % in terms of heterosis (F$_1$/Midparent) with the grand mean of 150.5%, and, 86.1-179.8% in terms of heterobeltiosis (F$_1$/better parent) with the grand mean of 125.3%. Among the female parent groups, Chinese mainteiners were the highest following by Chinese MS lines and the Korean maintainers were the lowest. Heterobeltiosis of yield components were 92.7%, 120.0%, 103.0% and 112.0% for number of panicles/unit area, number of grains/panicle, fertility per cent and 1000 grain weight, respectively. Path-coefficients of yield components to the yield were calculated. The highest one was number of grains per panicle ranging 0.8073-0.8649 followed by the 1000 grain weight ranging 0.2000-0.5032. The grain yield ratios to the grand mean were calculated in terms of combining ability. It was highest with the Chinese maintainers followed by Chinese MS lines and The Korean maintainers were lowest. This facts bring cautions to the breeding efforts to transfer the Chinese CGMS in to Korean maintainers.

  • Heritability of flowering date, length of main stem, weight of 100 grains and number of shells per square meter in peanut were high with low local variation. There was positive genotypic correlation between length of main stem and yield, No. of shells per square meter and matured seed ratio, No of shells per square meter and yield 100 grain weight and yield but was negative genotypic correlation between flowering date and yield. With the view of path-coefficients, length of main stem, number of shells per square meter showed highly direct effects at.. all locations.

  • 본 논문에서는 색상 변화 분석을 통하여 차량의 속도와 수량을 측정하는 방법을 제안한다. 동영상에서 색상 변화를 분석하기 위하여 시간 흐름에 따른 화소의 색상 변화를 그래프로 표현한다. 차량 진행 방향에 있는 두 개의 화소에 대하여 이 그래프를 구하여 두 그래프가 가지는 시간차이를 계산하여 이동하는 차량의 속도를 구한다. 차량의 진행 방향을 추정한다. 차량의 수량은 도로 색에 경계 값을 설정하여 구하고, 이를 속도로 보완한다. 제안한 시스템은 날씨와 밝기에 영향을 적게 받으며 수행시간이 적게 드는 장점을 가진다.
