2017—2018年淮山新品种区域试验

The Regional Test for New Varieties of Yam during 2017-2018

为适应生产与市场的需求,筛选出适合福建主产区种植的淮山新品种。以寸金薯为对照,于2017—2018年在泉州德化、龙岩连城及南平建阳等地进行2年淮山品种区域试验,对参试新品种的田间试验、室内检测数据进行统计分析,重点进行丰产性和适应性鉴定,并结合其主要农艺性状、生物学特性、抗逆性、块茎品质等方面进行综合分析与评价。结果表明,V10(泉淮红皮白肉)中熟优质丰产稳产,是综合表现最好的品种;V1(台淮6号)中熟优质丰产、较稳产;V6(泉淮1547)中晚熟、较丰产稳产、商品率高;V8(泉淮1515)中熟高产稳产;在其适应种植区域均有应用价值。V4(泉淮1517)中熟丰产不稳产、商品性差,V5(泉淮1542)、V9(大铭薯)和V3(泉淮1513)中晚熟产量品质一般,可用作亲本杂交材料选配新组合;V7(下涌薯)中熟产量一般、商品性差,应用价值较低。

In order to meet the needs of production and market, new yam varieties which could be suitable for cultivating in main producing areas of Fujian were bred out.Cunjinyam was used as the control.The two-year regional test of yam varieties was conducted in Dehua,Liancheng and Jianyang of Fujian during2017-2018.The field test and laboratory test data of the new varieties were statistically analyzed.Identification of fertility and adaptability was the key.The main agronomic characters, biological characteristics, stress resistance and tuber quality were analyzed and evaluated.V10 (Quanhuai red skin white meat) was the best variety with high quality, high yield and stable yield.V1 (Tai huai No.6) showed medium maturity,high quality and stable yield.V6 (Quanhuai1547) showed medium and late maturity, relatively high and stable yield and high commodity rate.V8 (Quanhuai1515) showed medium maturity, high yield and stable yield. They have application value in the suitable planting area.V4 (Quanhuai1517) showed medium maturity, high yield, unstable yield and poor commodity performance.V5 (Quanhuai1542), V9 (Daming potato) and V3 (Quanhuai1513) showed medium and late maturity, unstable yield and poor commodity performance. They could be used as parents to select new combinations of hybrid materials.V7 (Xiayong potato) showed medium maturity,moderate yield, poor commodity and low application value.
