The genetic variances of plant height, stem length, stem yield and seed yield were greater than other characteristics. The broad-sense heritability of maturation time, seed yield and stem length were higher, but stem yield was lower. The genetic correlation coefficient between seed yield and stem yield showed highly significant positive correlation, and that between maturation time and flowering time also showed positive correlation. But the correlation coefficient between maturation time and seed yield showed negative correlation. Path coefficient analysis indicated that plant height and stem length showed direct effects on stem yield, and flowering time and maturation time also showed direct effects on seed yield.

Hi Jin Park(朴熙塡),Byung Sun Kwon(權炳善),Jung Il Lee(李正日) 한국육종학회 1990 한국육종학회지 Vol.22 No.1

Ninety one flax cultivars were largely classified into eighty varietal groups, and five groups out of them forming the group by one variety showed low variation whereas the others showed high. Group Ⅰ contained three cultivars(3%), Group Ⅲ and Group Ⅳ did seventy five (82%) and eight(9%), respectively. Group Ⅱ, Ⅴ, Ⅵ, Ⅶ and Ⅷ were classified as one variety. Most of the varietal groups were not associated with their geographical origin. Date of flowering, date of maturing and stem length among the eight characters were the largest contributors to the D² in both intra and inter groups.

In order to obtain the genetic information on the quantitative characters of Cassia tora L. which would be needed to improve selection efficiency for breeding high yielding genotype, twenty one varieties of Cassia tora L. collected in Korea were grown and variations of several important characters were observed. Heritability of each observed character, phenotypic and genotypic correlations among the characters, and contribution of each yield component on grain yield through path coefficient analysis were estimated. Both stem diameter and number of grains per pod showed not only high heritability but also highly significant phenotypic and genotypic correlation with grain yield, and hence it was desirable to select plants with thicker stem and higher number of grains per pod to raise grain yield of Cassia tora L. In addition, number of grains per pod and 1000 grains weight were proved to be the most influential variables on the variability of grain yield by path coefficient analysis. Since here showed the high heritability of number of grains per pod, selection of plants with higher number of grains per pod would be more efficient for breeding high yielding genotype.

This experiment was conducted to select useful mutants in three rapeseed varieties, Naehan, Youngsan, and Mokpo-59, treated with gamma-ray 30 KR. One hundred and ninety seven mutant lines in Naehan, 131 in Youngsan and 256 in Mokpo-59 were evaluated for flowering date, plant height and other characters compared with their mother varieties in M₂ generation. The results obtained are summarized as follows : More than 94% of the mutants matured earlier for flowering date and 75% were shorter in plant height while ear length appeared the same or increased as compared with their mother varieties. These mutants in the M₂ generation were able to be selected. Two mutant lines in Naehan and Youngsan, and three mutant lines in Mokpo-59 were selected for early flowering date, shorter plant height and longer ear length, respectively. Mutants had more branches above 78%, 27% for the first and the second branch, respectively. Mutants with more pods per ear were able to be selected in the mutant populations as compared with thir mother varieties. Four mutant lines in Naehan and Youngsan and three in Mokpo-59 with more branches and pods were selected, respectively.

Sixty four wanggol cultivars were largely classified into ten varietal groups, and six groups out of them forming the group by one variety to high variation in various characteristics whereas the others tended to low. Group Ⅰ and Group Ⅴ contained fifteen (23%) and thirty nine cultivars(61%), respectively Group Ⅱ showed medium or late flowering, but Group Ⅴ revealed early flowering and considerably large variation in various characteristeics. Most of the varietal groups were not associated with their geographical origin. Days to flowering and plant height among the nine characters were the largest contributors to the D²in both intra and inter groups.

The results of comparing and analyzing the emergency operation collected from KwangjuㆍChonnam Fire Department with national data from Jan. 1 to Dec. 31, 1994 are as follows. The possession of ambulance in Kwangju is the 3rd among 6 large cities and the security rate of experts in emergency first aid is the 4th, and in the case of Chonnam, the possession of ambulance is the 7th among 9 provinces and the security rate of experts in emergency first aid is the 5th. So, two regions are not reached at the national mean and the appointment rate of emergency medical institution in Kwangju is 10.8% and it is the highest among 6 large cities, but that of Chonnam is 13.8% and it shows low secure rate as the 5th of 9 provinces. The transfer rate of emergency cases in Kwangju is 75.3% and it is the 3rd among 6 large cities and that of Chonnam is 86.8% which is high following Cheju that has 89.6%. First aid of experts in emergency is composed of aerobic respiration, angiostasis and artificial respiration and in emergency cases by medical clinics, the cases of internal department are the most as the 46.6%, those of surgery are 37.1% and those of pediatrics are 3.1%. In the necessary time of transfer, 51.9% is within 10 min., 26.7% within 20 min. and 78.6% of total cases is within 20 min., and the time period of emergency cases is between 22:00 and 02:00 before and after midnight, that of gas poisoning cases is between 04:00 and 10:00 and that of burn cases is noon and between 18:00 and 20:00, and so it is most frequent at mealtime. In the number of cases by sex, male patients are 56.6% and by age, accident cases are frequent in thirties and acute and chronic cases are frequent over 60 years old. By occupations, housewife and the unemployed occupy about 50% except traffic accident and it is shown that acute and chronic diseases and safety accident are frequent in housewife, children and the aged.

氣象 環境要因이 亞麻의 收量에 미치는 影響

朴熙塡 서강정보대학 1993 論文集 Vol.12 No.-

To study the relationships between flax yields and meteorological elements, the investigation into the important agronomic characters of Wiera cultivar and climate factors such as maximum temperature in June from 1983 to 1992 was made. Yearly variation of c.v.(%) were highly significant for yield and the important agronomic character. The analysis of variance for agronomic characters following the difference of maximum temperature in June during the 10 years, were acknowledged to be worth of attention. Correlation coefficients between maximum temperature of June and yields or agronomic characters were significantly negative. Regression equations between the maximum temperature of June and stem or seed yield were Y = 837.94 - 15.55 X and Y = 252.90 - 6.25 X, respectively. High temperature of June affected flax yield (stem and seed) reduction significantly.
