Abstract
本研究系由不同來源之甘藷品種保存材料中，逢機取出143個品種，在秋作同一生長條件下，進行有重複的田間試驗，並在4個不同生育期中，分別測定乾物重的收獲指數，以供研究甘藷品種間收穫指數之變異情形之及與塊根收量等性狀之關係。另以3個不同植物性狀之品種，在4種不同種植密度下，探討收穫指數對塊根收量等之影響，以期有助於甘藷品種改良工作之參考應用。
One hundred and forty-three genotypes selected randomly from a wide source of germphasm collections of sweet potato were grown in a replicated field trial under similar cultural management in fall planting. The data on harvest index were calculated from dry weight measurement of top and root yields at four different growing periods to investigate the variation in harvest index and its correlation with root dry weight and other triats in sweet potatoes.
