摘要: 在观赏桃育种过程中获得了1 份特殊材料‘PCM-1’,花为粉—白杂色,叶片为紫红—绿杂
色,嫩茎表面有紫红色条带或细点,幼果表面有不规则红色斑块或细点。从杂色性状的形态学特性、无
性繁殖表现和有性遗传规律对其进行了初步探索,并进行了其亲本和无性系的SSR 鉴定。连续6 年观察
发现‘PCM-1’的杂色性状稳定;徒手切片观察到杂色均出现在表层的第一层细胞。嫁接繁殖表明杂色性
状稳定(97.4%),但无性系中也能分离出较低比例的纯色株系(2.6%);花、果、叶、嫩茎4 个部位的杂
色具有同步性。以‘PCM-1’为母本,与花色纯白、叶色纯绿的父本杂交,后代中能够出现12.2% ~ 24.7%
的杂色单株。通过SSR 鉴定发现‘PCM-1’的母本为‘红粉佳人’;经324 个SSR 标记鉴定,‘PCM-1’
(杂色)、‘PCM-1R’(纯红)和‘PCM-1G’(纯绿)3 个无性系间未发现等位基因差异。

Abstract: A peach‘PCM-1’,with variegated color was obtained in breeding practice of ornamental
peach. The variegated color was pink and white on flower,purple and green on leaf,purple strips or dots
on green stem,and irregular red spots or dots on young fruits with green background. In this study,
morphology,transmission among grafted clones and inheritance of the variegated color were investigated.
By using SSR,parent of‘PCM-1’and difference among grafted clones were identified. Variegated color
was stable during 6 years of observation on‘PCM-1’. Colorful cells were only observed in the first layer
on the epidemic of petal,leaf and stem. By grafting,most clones(97.4%)carried variegated color
predicting the trait could be transmitted by grafting,but a few clones(2.6%)with pure color were also isolated. The variegated color on flower,leaf,stem and fruit appeared simultaneously on the same plant.
By crossing‘PCM-1’with white flowered and green leafed peaches,12.2%–24.7% of individuals with
variegated color were observed.‘Hongfen Jiaren’,a released ornamental peach,was identified to be the
female parent of ‘PCM-1’. By screening 324 SSRs,no different alleles were observed among three clones,
‘PCM-1’,‘PCM-1R’and‘PCM-1G’,although their leaf color are variegated,pure purple and green,
respectively.

Key words: peach, variegated color, characteristic, inheritance, SSR
