芍药属植物杂交育种研究进展

Progress in Paeonia Crossbreeding Research

从芍药属组内及组间杂交育种两个方面综述了芍药属杂交育种的研究进展:组内育种成果主要为黄牡丹杂种、芍药(Paeonia lactiflora)品种群和杂种芍药,组间育种成果则以Itoh杂种为主;已有的优异新种质主要为欧美日等国家创制;中国芍药属杂交育种成果与国外相比差距较大。建议未来中国芍药属杂交育种工作应从野生种质资源保护、国外优异种质引进、亲本组合选配、杂交障碍机制深入研究及育种工作持续开展等5个方面进行。

Crossbreeding is a valuable method for producing new plant varieties with desirable characters. So far, this traditional method is still the major approach for breeding new Paeonia varieties. This paper reviewed the progress in Paeonia crossbreeding program. The typical achievements via intrasectional crossing mainly include＂ Lutea Hybrids ＂, ＂P. lactiflora Group＂and＂ Herbaceous Hybrids＂, while ＂Itoh Hybrids＂ represents the achievement of intersectional crossing. These distinctive genotypes were mainly developed by breeders from Europe, America and Japan. In comparison, only limited achievement was obtained by Chinese breeders. To promote future Paeonia crossbreeding program in China, we suggested more efforts be made in the five fields, i.e., protection of wild germplasm resources, introduction of elite genotype, efficient selection of parental combination, in-depth study on mechanism of crossing barrier and consistent performance of crossing experiments.
