摘要:

连续开花(Perpetual blooming,PB)是观赏植物的重要性状之一,是中国月季对现代月季
的重大贡献。然而月季连续开花性状的遗传基础至今尚未清晰。为研究中国古老月季品种‘月月粉’(Rosa
chinensis‘Old Blush’,用OB 表示)连续开花习性的遗传规律,以其为母本,以一季开花(Single seasonal
blooming,SB)园艺品种‘无刺光叶蔷薇’(Rosa wichuriana‘Basye’s Thornless’,用W 表示)为父本,
构建了OB、W、F1、F2、BC1OB 和BC1W 等6 个世代827 个株系的二倍体遗传分离群体。遗传分离群体
表型测定将开花表型分为连续开花和非连续开花(Non-perpetual blooming)2 种类型。296 株F1 和150 株
BC1W 群体均表现为非连续开花,表明OB 连续开花性状受隐性基因位点调控。300 株BC1OB 群体中83
株为连续开花,223 株为非连续开花,χ2 适合性测验符合1︰3 的遗传分离规律(P < 0.05),表现为双隐性
基因遗传,表明‘月月粉’连续开花可能受双隐性基因位点共同调控。

Abstract:

Perpetual blooming is one of the most important trait of ornamental plant,and it is the huge
contribution of Chinese rose(diploid rose)to modern rose(tetraploid rose)breeding. However,the genetic
basis of this trait is still largely unknown. In order to investigate the inheritance of perpetual blooming
behavior in Rosa chinensis‘Old Blush’(OB),we developed six rose populations(OB,W,F1,F2,
BC1OB and BC1W)derived from WOB population[interspecific diploid hybrid between OB and Rosa
wichuriana‘Basye’s Thornless’(W)]. Perpetual blooming trait was analyzed as a major gene,and
blooming behavior of each individual was evaluated at Flower Research Institute,Yunnan Academy of
Agricultural Sciences(Kunming,China)from 2012 to 2015. Perpetual blooming type is absent both in a
F1 population with 296 genotypes and a BC1W population(Rosa wichuriana‘Basye’s Thornless’as a
backcross parent)with 150 individuals. More interesting is,a backcross population BC1OB(Rosachinensis‘Old Blush’as a backcross parent)with 300 progenies showed a 3︰1(P < 0.05)segregation ratio
in blooming behavior(non-perpetual blooming dominant to perpetual blooming). The results indicate that
the inherence of perpetual blooming in rose might be regulated by double recessive loci.

Key words: rose, Chinese rose, perpetual blooming, segregating population, double recessive
loci
