Abstract：The new bitter gourd variety Liangli No.3 is a new mid-early maturity and heat-tolerant first-generation hybrid bitter gourd variety,developed from a high-generation inbred line TS-087(female parent)crossed with another high-generation inbred line TS-367(male parent).This variety exhibited vigorous growth potential,strong branching ability,and produced the greenish-white,medium-length,round-grained tubers with short longitudinal ridges.It had high female flower rate and strong fruit-setting ability,with the first female flower occurring at the 11th to 13th node.The gourd was 26 to 32 cm in length,5 to 7 cm in diameter,with a flesh thickness of about 1.3 cm and a single gourd weight of 450 to 500 g.The fruit was evenly and neatly hung,with a high commercial yield and a glossy and oily fruit skin.It had strong resistance to powdery mildew and high yield.The variety comparison test and the regional multi-point test in Fujian Province were carried out in the autumn of 2021 and the autumn of 2022,respectively.In the variety comparison test,the average yield of Liangli No.3 over the two years was 41 340.00 kg·hm-2,which was 12.8%higher than that of the control variety Xinhuayu.In the regional multi-point test in Fujian Province,the average yield of Liangli No.3 in two years was 41 513.67 kg·hm-2,which was 11.8%higher than that of the control variety Xinhuayu.The protein content of Liangli No.3 was 0.84 g·hg-1,the moisture content was 94.9 g·hg-1,the ascorbic acid(vitamin C)content was 84.1 mg·hg-1,and the reducing sugar content was 0.54 g·hg-1.The comprehensive analysis indicated that this variety was suitable for the open-field cultivation in Fujian during both summer and autumn seasons.
