【目的】选育抗病性强、品质优良、高产稳产且适合广西种植的葡萄新品种,为广西葡萄产业可持续发展打下基础。【方法】2009~2013年,对从巨峰葡萄群体中选出的优良芽变单株分别进行品种比较试验和区域栽培试验,观测其栽培性状和果实品质。【结果】品比试验中,该芽变单株第一季果平均穗重376.7 g,平均粒重8.53 g,平均可溶性固形物含量15.9%,较对照巨峰提高了1.2%(绝对值);区域试验第二季果平均穗重约300.0 g,平均粒重约7.30 g,平均可溶性固形物含量约19.0%。产量方面,品比试验第2年开始挂果,单株产果2.79 kg,第一季果产量为7449.0 kg/ha;区域试验第3年进入丰产期,都安县试验点第一季果产量为14874.0 kg/ha,第二季果产量为7326.0 kg/ha。该品种于2014年6月通过广西农作物品种审定委员会审定,定名为桂葡4号。桂葡4号表现果穗中等大,果肉质细,有浓郁的草莓香味,对葡萄黑痘病及灰霉病抗性较强,对霜霉病、炭疽病抗性中等,高产稳产,在广西可进行一年两收栽培。【结论】桂葡4号综合性状优良,可进行一年两收栽培,避雨栽条件下适合在广西等南方地区推广种植。
【Objective】 Breeding new varieties of grapes with high disease resistance, good quality, high and stable yield and suitable for Guangxi planting laid the foundation for the sustainable development of Guangxi grape industry. 【Method】 Between 2009 and 2013, comparative experiments and regional cultivation experiments were conducted on finely-transformed single plants selected from the Kyoho grape group, and their cultivation traits and fruit quality were observed. 【Result】 In the product ratio test, the average spike weight of the first season fruits was 376.7 g, the average grain weight was 8.53 g and the average soluble solid content was 15.9%, which was 1.2% (absolute value) In the second season, the average ear weight was about 300.0 g, the average grain weight was about 7.30 g and the average soluble solids content was about 19.0%. In terms of yield, the fruit yield was 2.79 kg per plant per plant in the second year after the test. The output of the first quarter was 7449.0 kg ha-1. In the third year of regional trial, the yield reached 148,74.0 kg / ha in the second season and 7326.0 kg / ha in the second season. This variety was approved by Guangxi Crop Variety Approval Committee in June 2014 and is named as Guigui No.4. Guigui 4 medium-sized performance of the ear, fruit fleshy, rich strawberry flavor, strong resistance to grape black pox and gray mold disease, resistance to downy mildew, anthracnose, high and stable yield in Guangxi Harvest cultivated for two years a year. 【Conclusion】 Guigui No.4 comprehensive trait is good and can be cultivated in two harvests a year, which is suitable for popularization in the southern part of Guangxi such as Guangxi under rain-shelter conditions.
