摘要
通过20个月季品种380个组合的杂交试验表明,月季花粉的萌发率是影响月季杂交结实率的关键因素,但不是唯一因素,其花粉的萌芽率基本与杂交结实率成正相关。筛选出阿斑斯、黑巴克、地平线和木瓜粉为较好的母本材料。杂交结实率主要决定于父母本的亲和性。自交结实性可作为选择亲本的依据之一。采用正反交可提高获得杂交后代的机率。结实率还受气候条件的影响,应结合当地的气候条件来选择授粉的最佳时期。
The study of 380 cross combinations involving 20 cut flower cultivars of Chinese rose （Rosa chinensis L. ） showed that pollen germination was the key factor influencing their cross fruitfulness and a positive correlation was noticed between them. Self-fruit set percentage may be taken as an important indicator for the choice of parents. The cuhivars Ambiance, Black Baccara, Skyline and Muguafeng were identified as excellent maternal parents. The compatibility between the parents was the main factor for fruit set percentage. Climate also showed some effect on fruit-set.
