节瓜耐热材料的创制及新品种选育

鉴于长期缺乏耐热的节瓜品种,开展了节瓜耐热材料创制及新品种选育等为主要内容的育种研究.结果表明:主侧蔓坐果育种材料可以作为耐热资源进行利用.经组合选配、品比试验、区域试验、生产示范等一系列环节,育成节瓜新品种夏冠一号.生产示范及推广表明,夏冠一号具有耐热兼高产的特性,是目前华南地区夏季高温栽培的适宜品种.2005年通过广东省农作物品种审定.

Development of chieh-qua materials and new variety with heat tolerance

Studies on development of chieh-qua materials with heat tolerance were carried out for the lack of corresponding variety.The results showed that:materials setting fruits on main and lateral stems can be utilized for the breeding.Xiaguan1 was thus developed after a series of trials.The variety is tolerant to heat and suitable to grow in summer in South China.Xiaguan1 was registered by crop varieties approving committee of Guangdong province in 2005.
