택사 종자의 펠렛화를 위한 피복 재료를 선발하기 위해 기존에 개발되었거나 농업적으로 이용 가능한 재료들을 사용해 본 시험을 수행하였다. 펠렛 종자의 모양형성은 피복 재료의 종류에 따라 좌우되었으며 대체로 단용재료나 2종의 혼합재료에 비해 3종의 혼합재료가 펠렛 형성이 잘되고 수분 흡수후 펠렛의 열개성이 우수했다. 특히 SDZ+DE+CA $0.4\%$의 혼합물이 발아율 및 발아세가 $95.3\%$로 가장 높았고 생력 기계파종을 위한 물리적 특성도 좋아 펠렛 종자의 피복 재료로 가장 양호하였다. Alisma plantago seeds have some difficulties for mechanical sowing because of small, irregular and shrunken shapes. Thus it was intended to make seed pelleting for Alisma piantago seeds to solve these problem. The main object of this study was to find the best materials for Alisma plantago seeds pelleting. The most desirable shapes which provide a spherical and smooth surface of the pelleted seeds that enhance mechanical singling was made from the mixture of SDZ + DE + CA $0.4\%$. The pelleted seeds were easily broken after absorbing water and the germination rate of those was $95.3\%$ in lab.

To Study the relationships between rapeseed yield and meteorogical elements, the investigation into the important agronomic characters of Yudal cultivar and climate factors such as precipitation, and temperature from 1975 to 1984 was made. Yearly variation of C. V.(%) were highly significant for yield and the important agronomic character. Correlation coefficients between precipitation of May and Yield or agronomic character were significantly positive. Regression equations between the precipitation of Mayor minimum temperature of February and yield were Y=210.914+1.719X and Y=245.560-1.720X, respectively. Low temperature of February affected rapeseed yield reduction significantly.

This experiment was carried out for estimating genetic parameters, such as heritabilities, the phenotypic and genotypic correlation of major agronomic characters of 38 cultivars in mat rush. Heritabilities of flowering date, number of stem per plant, fresh weight of stem, dry weight of long stem, dry weight of middle stem and dry weight of short stem were higher, but that of maturing date and stem length were relatively lower. The genotypic correlation coefficients between number of stem per plant and dry weight of long stem, and between dry weight of middle stem and dry weight of total stem showed highly positive correlation, and number of stem per plant, fresh weight, dry weight of long stem and dry weight of middle stem were significantly correlated with yield[dry weight of total stem], those characters gave high direct effect as same level in path-coefficient analysis.
