牡丹经长期人工栽培和自然杂交,其遗传基础已经动摇,容易发生变异。又由于它是异花传粉植物,因此用混合授粉法进行人工杂交,即可从其杂种后代中选育出新品种。山东菏泽花农就是采用这一方法,选育出了上百个牡丹新品种。混合授粉法简便易行,不需要复杂的设备,也无需去雄、套袋。凡有牡丹栽培的地方和单位,均可开展此项工作。一、父本的选择与花粉收集可选择多个优良牡丹品种,如姚黄、胡红、鲁粉、十八号、首案红、迎日红、大棕紫、烟绒紫、青龙卧墨池等;也可选择紫斑牡丹的一些品种及国外引种的牡丹品种作为父本。开花初期,将这些品种花朵中的花药用镊子采集下来摊于白纸上,放在通风处,使花粉散 Peony cultivation by long-term and natural hybrids, the genetic basis has been shaken, prone to mutation. Since it is a cross-pollination plant, hybrid pollination is used for artificial breeding to breed new varieties from its hybrid offspring. Heze, Shandong flower farmers is the use of this method, breeding hundreds of new varieties of peonies. The hybrid pollination method is simple, does not require complicated equipment, nor does it need to be sterilized or bagged. Where peony cultivation places and units, can carry out this work. First, the choice of father and pollen collection You can choose a number of excellent varieties of peony, such as Yao Huang, Hu Hong, Lu powder, on the 18th, the first case of red, welcome day red, big brown purple, tobacco velvet purple, Pool, etc .; also choose some varieties of purple peony and the introduction of foreign varieties of peony as a male parent. Early flowering, the anther in these varieties of flowers collected with forceps down in white paper, placed in ventilated place, pollen powder
