高产抗病籽瓜新品种SWBB-01的选育

[目的]选育适宜新疆种植的高产抗病籽瓜品种.[方法]以母本XR3110与父本IR5106杂交,再以XR3110作为轮回亲本进行回交,对后代进行连续自交纯化选育而成,并进行多点品种比较试验及生产试验,确定其高产稳产适应性.[结果]在品比试验中,籽瓜新品种SWBB-01两年三点平均产量155.1 kg/667 m2,较新籽瓜1号(CK)增产13.39;,较SWBB-C增产11.85;,居第一位.在多点生产试验中,新品种SWBB-01平均产2 145.87 kg/667 m2,较CK增产14.57;,呈极显著水平,抗白粉病、枯萎病.[结论]SWBB-01在产量及病害抗性上表现突出,2010年10月通过了新疆维吾尔自治区非主要农作物品种审定委员会审定(审定号:新登籽瓜2010年35号).命名为SWBB-01.适宜在新疆乌鲁木齐、昌吉、伊犁、巴音郭楞州等地及阿勒泰、塔城地区部分产区种植.

A High Yield and Disease Resistance New Variety of Seed Watermelon-'SWBB-01'

【Objective】The purpose of the project is to select the suitable seed of a seed-watermelon variety to be planted in Xinjiang which can yield high output and resist diseases.【Method】 Female parent XR3110 was hybridized with male parent XR3110 and then XR3110 was used as recurrent parent to be backcrossed.Their offspring will go several rounds of sefling before the pure fine seeds are bred.Its stable high yield and adaptability can not be established until it experiences comparison and production trials in several plots.【Result】The yield of new variety of seed watermelon 'SWBB-01' which is produced in three plots for two years is 155.1 kg/667 m2 and is the highest of all varieties during the comparison trial,and meanwhile the yield of 'SWBB-01' is 11.85% higher than that of SWBB-C and 13.39% higher than that of the new seed-watermelon(CK).In several production trial plots,the average yield of 'SWBB-01'is 145.87 kg/667 m2,14.57% higher than that of CK,and it can resist the disease of powder and wilt.The suitable density is 3 600-4 200 zhu/667 m2.【Conclusion】The new high yield and disease-resistance variety 'SWBB-01' has passed the identification of Xinjiang Incidental Crops Variety Releasing Committee in 2010.This variety is suitable to be planted in Urumqi,Changj,Ili,Bayingol Mongolian Autonomous Prefecture and some parts of Altay and Tacheng Prefectures.
