In the fall of 2005, excellent material with good shape and strong growth potential was isolated from Guangdong local variety of ＇Jiangxinjie＇ , followed by three generation inbred lines selection, and finally inbred lines ＇Jiangxinjie No. 6＇ with marketable fruit length of 17-18 cm were obtained. Five combinations were obtaitled in the fall of 2007, through screening, variety test and provincial trials, a new line ＇Linghong＇ （strong female lines of No. 4×Jiangxinjie No. 6） with high-quaLity and high-yield was selected. ＇Linglong＇combined the male and female advantages, with strong growth potential, high heat resistance, wide adaptability, early maturity, good quality and good commodity. The fruit is in cylinder shape, 16-18 cm in length and 7.0-7.9 cm in diameter, with dark green skin. The white flesh is firm and mildly flavored, 1.5 cm in thickness. The hybrid is suitable for growing in Guangzhou area from late Janury to March and July to August. The hybrid passed Guangdong Provincial Variety Approval Committee in 2012.
