영문 초록

The objective of this study was to provide usefull selection information for improving rapeseed and oil cake quality. The data collected from the performance yield trials from 1978 to 1980 were used in this study. The genetic variance of plant height, flowering data and maturity date were great, but the year variation of these characters were small. The year variation of other characters were great. The genetic correlation among flowering date, maturity date and spike length were positive. The number of pods per spike was positively correlated with flowering date, maturity date and plant height. There were positive genetic correlations between 1000 seed weight, plant height and spike length. However, the genetic correlation between number of pods per spike, number of branches and number of filling seeds per pod were greatly varied with year.
