苦瓜新品种利农E39吉早的选育

Breeding of a new bitter gourd cultivar Linong E39 Jizao

摘要

利农 E39 吉早是以自交系 EG1706-4 为母本、自交系 B6039 为父本杂交选育而成的早中熟苦瓜新品种。该品种植株生长势强，分枝性强，主侧蔓均可结瓜，坐果率高。露地播种至初收春季约 76 d、秋季约 57 d。瓜长圆锥形，瓜色绿有光泽，条瘤顺直，外形美观。平均瓜长 30.3 cm、横径 6.7 cm, 果肉厚度 1.1 cm, 单瓜质量 500 g, 一般栽培 667 m²产量 2400 kg 左右。肉质脆嫩，味苦甘适中，中抗枯萎病。适宜广东省春、秋种植及生态条件相似的地区栽培。2023 年通过广东省农作物品种审定委员会品种评定。

Abstract

Linong E39 Jizao is a new early-maturing bitter melon variety developed by crossing the inbred line EG176-4 as the female parent and the inbred line B6039 as male parent. This variety exhibits strong plant growth and branching ability, with both and lateral vines capable of bearing fruit, resulting in high fruit setting rate. The time from sowing to first harvest is approximately 76 days in spring (57 days in autumn) in open field conditions. The fruit is long and conical, with green, lustrous skin, straight ridges, an attractive appearance. On average, the fruit length is 30.3 cm, the diameter is 6.7 cm, the flesh thickness is 1.1 cm, and the single fruit mass is 500 g. The yield is around 2400 kg·667 m^-2 in general cultivation conditions. The quality is excellent, with moderate bitter taste, and it shows intermediate resistance to Fusarium wilt. It is suitable for spring and autumn in Guangdong province and in regions with similar ecological conditions.
