Comparisons of yield potential in spring and autumn sowing cultivation of rapeseed (Brassica napus L.)
The purpose of this trial was conducted to test yield potential in spring and autumn sowing cultivation. Field tests were conducted with F1 hybrids of two cultivars of Sunmang and Chungram and pedigree lines of two cultivas of Hallayuchae,and Tamlayuchae during two years at Muan county(the north latitude 34°58, the east longitude 126°27) of southwestern peninsula. The yield potential of autumn sowing cultivation was higher than those of spring sowing cultivation. Because culturing periods of spring season was shorter than those of autumn season. In spring and autumn sowing cultivation, all the investigated morphological characters are shown to a higher extent in the composite F1 hybrids compared to the pedigree line. F1 hybrids had a greater yield potential because the yield components such as number of productive plants per m2, siliqua per plant, and seeds per siliquae were higher than those of pedigree lines.
