摘要
198 8～ 1 989年在哈尔滨市第三苗圃进行了丁香属 (SyringaL .)植物种间 (内 )杂交试验。结果表明 :( 1 )不同杂交组合的亲和性差异很大 ,在试验的 1 8个杂交组合中有 5个杂交组合得到了发育正常的杂种F1代种子 ,但结实率不同 ,其中以白丁香与洋丁香为亲本的杂交组合 ,无论是正交或反交 ,杂种F1代的结实率均达 86 %以上 ,表现出较高的亲和力。而以重瓣洋丁香为母本 ,白丁香为父本的杂交组合 ,杂种F1代结实率仅有 8% ,亲和力显著下降。 ( 2 )丁香种间杂交可以获得成功。杂种F1代长势旺盛 ,花色变异丰富 ,瓣性遗传性较强 ,已发现若干符合育种目标的新类型。
Interspecific hybridization among Syringa had been studied from 1988 t o 1989 in the 3th nursery, Harbin. The result showed: (1) There was big affin i ty difference among the different crossing groups. 18 crossing groups were resea rched, 5 of them got normal F1 hybrids seeds, but their fruit setting percenta ge was different. After reciprocal crosses of S.alba and S. vulgaris, t he fruit setting percentage of F1 hybrids all surpassed 86 per cent and displaying highe r affinity, however in S. vulgaris var. plena (female parent ) and S.a lba (male parent), the fruit setting percentage of F1 hybrids only reached 8 per cent, affinity dropped obviously. (2) The interspecific crossing in Syringa can succeed , with F1 hybrids grow th w ell, flower colour variability abundant and inheritance on petal stronger. Some new cultivars according with the breeding goal had been found.
