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.

The Gene action for eight quantitative characters related to the plant type was estimated using diallel cross among three different plant types of sesame (Sesamum indicum L.) in 2001. The parental varieties used for diallel cross were Ahnnam and Yangbaeck as indeterminate type, ksan22 as semi-determinate type, and dt-45 and Suwon131 as determinate type. In variance and covariance analysis (Wr-Vr) for eight characters the mean square of array except for capsule length, 1,000 seed weight were significant, which suggest that varieties involved in diallel set cross may have epitasis. Complete dominance was observed in the flowering periods, and ratio of matured grains while partial dominance was observed in the plant height, no. of capsules per plant, and no. of branch per plant. Broad sense heritability for flowering periods, plant height, no. of capsules per plant, and no. of branch per plant ranged from 0.91 to 0.99. Narrow sense heritability for flowering periods, capsule length, ratio of matured grain, 1,000 seed eight were 0.18 to 0.34, and plant height, no. of capsules per plant and no. of branch per plant were ranged 0.77 to 0.81.

The objective of this study was to compare year variations of heritability, phenotypic, genotypic and environmental correlations as well as pathway coefficients for main characters of tea tree to provide useful selection information for improving tea tree. The data collected from the performance yield trials from 1979 to 1981 were used in this study. 1. The genetic variance of height of stem and length of first branch was not only greatly varied with year. but also the largest among all characteristics studied. Other characteristics showed higher genetic variance than environmental variances, and year variances were very small. 2. Both year and variety x year interaction were highly significant sources of variation for height of stem, length of first branch and number of fruits in main stem pooled from three year data. 3. All characteristics showed high broad sense heritabilities, and the broad sense heritability was not varied with year. 4. The genetic correlation coefficients between Gigolpi and height of stem, length of first branch and number of fruits in main stem were positive, and the year variation was not large. 5. The pathway coefficients of the character was not only greatly varied with year and the height of stem, length of first branch and weight of dryed root affected directly on the Giglopi.

Ginseng plants in the 2nd year were grown under the shade (90-95%) of colored cellophane films at $15^{\circ}C$ in a natural light phytotron. Relative root grown (final/initial) was in decreasing order of blue, green, white, yellow and red. The growth of aerial part, especially stem length was poorest in blue light with relative root growth negatively correlated with stem length. In this relation each color showed specific domain. Stem length showed positive linear correlation with leaf area per plant in each and among light though it was not significant in red light. The content and ratio of chlorophyll a and b in leaf were in the decreasing order of White, Blue, Green, Red and Yellow. There is positive correlation between chlorophyll a and chlorophyll b, and between total chlorophyll and chl:a/b ratio. Blue color shade is expected to be beneficial for ginseng production.

In order to clarify the relationship between the characters and the influence of each character on the yield of perilla, correlation coefficients and path coefficients were calculated. The results obtained are summarized as follows; 1. A highly significant positive correlation was found between stem length and stem diameter, number of pods per plant, stem weight, respectively. Number of internodes showed also significant positive correlation , with number of pods per plant, stem weight, respectively as well as the relationship between number of valid branches and number of pods per plant. On the other hand, a significant negative correlation was appeared between number of valid branches and l000-grain weight as well as the relationship between number of pods per plant and l000-grain weight. 2. It seemed to be clear that stem weight, number of pods per plant, l000-grain weight, number of valid branches and stem diameter have direct and positive influence on the yield of perilla. 3. Indirect influence was observed between stem length and stem weight, between number of valid branches and number of pods per plant, and between number of pods per plant and stem weight, respectively. 4. It may be concluded that the yield of perilla is positively correlated with stem length, number of valid branches, number of pods per plant, l000-grain weight and stem weight.

This study was carried out to investigate the effects of planting density, time and frequency of pinching on growth and yield of Lycium chinese Miller cultivated in vinyl house. This experiment was conducted at the experimental field of Cheong-yang Agriculture High School, Cheong-yang, Chung-nam province, in 1997 to 1998. The number of flowers, fruit setting number and dry weight of fruits per branch were increased as the spacings were wider, but the fruit yield per unit area was decreased up to the narrowest spacing plot of $60\;{\times}\;20cm$. The good results of growth status and fruit yield was obtained at the early pinching in May 5. As the more frequent pinching were treated, the more number of flowers and fruits per branch were produced, showing increase of fresh and dry yield, because of much more branches per plot.

To investigate the effects of topping method on the yield and major agronomic traits of three varieties differed in plant type of Hibiscus manihot the experiments were carried out Mokpo Branch Station of Crop Experiment Station, in 1993. Fresh weight of root, dry weight of culm, dry weight of capsule and dry matter ratio on root were highest in the long culmed variety, and at the plots with topping of growing point in main culm and branches(Treatment No.3). Considering from the above results, optimum topping method seemed to be topping of growing point in main culm and branches in the long culmed variety.
