영문 초록

In order to obtain a basic data for the cultivation and the breeding of rape, grade of spring nature and the morphological variation to spring sowing time were investigated. Grade of spring nature could be classified to 8 classes by the method whether the material matured or not. In the morphological variation of useful characters, as the spring sowing time went to the later, the germinating was accelerated but the maturing time went to the later while hight, number of total branches, ear length, number of pods per ear., pod length, number of grains per pod, grain weight of 1,000 seed and oil content had a tendency to decrease so that might show a high negative correlation. The most proper lime of spring was also considered as February 23 to March 5 in the southern part of Korea.
