柑桔砧木育种研究进展

Advances in Citrus Rootstock Breeding

柑桔主要通过嫁接进行繁殖。柑桔砧木对接穗生长势、产量、果实大小、品质和抗性等都有直接的影响。砧木遗传改良是保持柑桔产业具有较强竞争力和较高生产力的重要步骤,世界各国都在致力于柑桔优良砧木的培育。本文就近几十年来柑桔砧木育种进展进行简要综述。

Citrus is mainly propagated by grafting. The rootstock directly affects the growth vigor, production, fruit size and quality, and stressesponsiveness of the scion. The health and productivity of citrus industry is greatly dependent on the performance of the rootstocks. The genetic improvement of citrus rootstocks has become a vital step towards the industry being more productive and competitive. In most of citrus growing countries, selecting and creating superior rootstock is one of the most important practices in citrus breeding. In this paper, the progresses in citrus rootstock breeding in the past decades will be briefly reviewed.
