영문 초록

Progenies of the crosses of tetraploids and diploid FDR(First Division Restitution) clones were clonally compared for true potato seed cultivation and tuber cultivation methods. Correlations were not observed for the tuber production between true potato seed and tuber cultivation methods. True seed obtained by open pollination of tetraploid clones and F₁ seeds obtained by crosses of tetraploid × FDR clones were cultivated in fall and spring. Total tuber production were higher in fall or in spring on the parents, however, marketable tubers (above 50 gram) were produced more in fall than in spring in all lines. Cross pollinated F₁ progenies were superior in the tuber production than the open pollinated progenies. This indicates that heterosis by genetic diversity is important in the true potato seed production.
