金花茶杂交育种研究

Intirspecific Cross Breeding for New Yellow Camellias

首次按花期、花径、重瓣性等项指标将不同金花茶进行了分类，为杂交亲本选择及应用提供了依据，对提高金花茶远缘杂交的座果率有重要参考价值。在大规模杂交中，初选出株型矮、花大、有香味、叶小的１０５杂种苗及‘新黄’、‘金背丹心’新品种，表明我国金花茶育种已取得初步成果。

The authors proposed to classify yellow camellia species by means of using cri-teria as floral characteristics like flower size and number of petals per flower.This svstemcan be used to select parents for cross breeding for new yellow camellias,Technique of cross-ing has been studied which is beneficial to assure higher percentage of setting in interspecifichybridization,After 20 years cross breeding we have made 300 cross combinations with a samtatal of pollinated flowers as many as 46128,resulted in obtaining 2 707 hybrid seedlings.Solne of the interspecific hybrids show characteristics of both parents.The comprehensiveanalysis of hybrid No. 105 (Camellia nitidissima×C. sasanqua)show that it is a true pro-mossing hybrid.
