栀子优良无性系选育研究

2009年通过初选、复选、决选选育出2个栀子优良单株，2014年在云南省景谷县和临翔区进行子代测定试验，连续2年定株观测其树高、地径、冠幅、开花量、结实量、适应性、物候，分析比较其主要内含物含量。结果表明：邦永3号和4号树势中等，适应性较强，丰产综合性状优良，内含物丰富，为优良无性系，通过良种认定。其中，邦永3号单株鲜果产量分别比CK增加56.3%、55.3%，其鲜花中的挥发油含量分别比CK增加41.67%、29.71%、54.99%，其果实的黄色素色价、栀子苷、皂苷分别比CK增加10.26%、75.36%、6.65%；邦永4号单株鲜果产量分别比CK增加50.0%、52.6%，鲜花中的挥发油、芳樟醇、罗勒烯分别比CK增加50.00%、27.30%、22.24%，果实中的黄色素色价、栀子苷、皂苷分别比CK增加6.89%、17.76%、4.98%。

Selection and Breeding of Superior Clones of Gardenia jasminoides

In 2009, 2 superior individuals of Gardenia jasminoides were selected through primary selection, re-election, and final selection. In 2014, the progeny test was conducted in Jinggu and Linxiang of Yunnan Province. For 2 consecutive years, the plant height, ground diameter, crown width, flowering amount, fruiting amount, adaptability, and phenology were observed. Analyed and compared its main contents. The results show that the trees of 'Bangyong No.3'and 'Bangyong No.4' are medium-sized, with strong adaptability, high-yield comprehensive traits, rich in contents, and excellent clones, which are identified by improved varieties. Among them, the yield of fresh fruit per plant of 'Bangyong No.3' increases by 56.3% and 55.3%, respectively. The volatile oil content in the flowers increases by 41.67%, 29.71% and 54.99%, respectively. The yellow pigment color and the geniposide of the fruit are increased. Saponins increased by 10.26%, 75.36%, and 6.65%, respectively, compared with CK. The yield of fresh fruit per plant of 'Bangyong No.4'increases by 50.0% and 52.6%, respectively. The volatile oil, linalool and basilene in flowers increases by 50.00%, 27.30% and 22.24%, respectively, the yellow pigment color, geniposide and saponin in the fruit increased by 6.89%, 17.76% and 4.98%, respectively, compared with CK.
