Breeding of a new large-size watermelon variety Guihong 2 and its cultivation technology
摘要
Abstract
[Objective]Experiments were conducted to breed a new first generation large-size hybrid watermelon variety with green strip skin, high and stable yield and strong resistance to diseases and aging in order to meet the diverse needs of watermelon industry. [Method]The self-bred lines xy-1-2-5-1-2 and Nb-3-3-1 were used as female and male parent, respectively, to develop 7 watermelon crosses in autumn in 1997. Field test and indoor evaluation of these combinations were carried out in spring and autumn in 1998. Multi-location demonstration and production in large areas were conducted from 2000-2010. [Result]A new large-size watermelon variety Guihong 2 with mid-maturity was bred. Its growth period was recorded as 100-105 d in spring and 75-80 d in autumn. It required 32-34 d from flowering to fruit maturity. The plant vigor and branching ability were found moderate with excellent fruit-setting and good resistance to anthraenose disease. The fruit appearance of Cuihong 2 was long ellipsoid with dark green stripes and green skin. The skin thickness was 1.0-1.2 cm with durable storage and transportation ability. The weight of single fruit was 7-9 kg with high and stable yield. Its flesh was red and crispy and the soluble solid contents were in range of 11-12% with good taste. Guihong 2 was certified and registered by Guangxi Committee for Crop Variety Registration in 2006. [Conclusion]Due to strong growth vigor and branching ability, high and stable yield, resistance to diseases, nice appearance and wide adaptability, it is recommended to be extended in watermelon producing areas of Guangxi and Hainan.关键词
