在甘薯育种中,多数育种者都认为甘薯产量与品质是负相关,且高产与稳产也常难统一。但这种矛盾并不是无法克服的,国内外也已出现一些成功的事例。江苏省农科院宁薯1、2号的育成和日本一些高产优质种的问世,都表明了育成既高产又优质的品种是可能的。
In sweet potato breeding, most breeders believe that sweet potato yield and quality are negatively correlated, and high yield and stable yield are often difficult to unify. However, this contradiction is not insurmountable and there have been some successful examples both at home and abroad. The successful establishment of Jiangsu No. 1 and No. 2 Agricultural Science Institutes and the advent of some high-yielding and high-quality varieties in Japan have shown that it is possible to cultivate both high-yielding and high-quality varieties.
