云南丽江适栽蓝莓品种筛选试验初报

为了了解不同蓝莓品种在云南丽江的丰产性和适应性,筛选出适合本地区种植的优质、高产蓝莓新品种,本研究通过8个兔眼蓝莓品种进行田间比较试验,采用灰色关联分析法对供试品种的结果枝数、每枝结果数、株高、单果重、单株一年生枝数、冠幅和单株产量等7个主要农艺性状进行灰色关联综合评价。以单株产量为参考数列,其他性状构成被比较数列,灰色关联序依次是：结果枝数＞每枝结果数＞株高＞单果重＞单株一年生枝＞冠幅。以理想品种为参考数列,其他品种为被比较数列,灰色关联序依次是‘芭尔得温’＞‘粉蓝’＞‘灿烂’＞‘杰兔’＞‘顶峰’＞‘园蓝’＞‘乡铃’＞‘梯芙蓝’。因此,以灰色关联分析法评估选出的‘芭尔得温’、‘粉蓝’、‘灿烂’、‘杰兔’4个品种,综合性状表现优,适合在丽江地区推广种植。

Adaptability Selection of Blueberry Varieties in Lijiang,Yunnan

To understand the high yield and adaptability characters of different blueberry varieties in Lijiang, Yunnan, and select new blueberry varieties with good-quality and high-yield which are suitable for planting in the region, we compared agronomic characters of 8 rabbiteye blueberry varieties, and assessed the main agronomic traits, including bearing branch number, fruit number per branch, plant height, fruit weight, annual branches, crown breadth, and yield per plant based on grey correlation analysis. The results showed that: with plant yield as reference sequence, and other characters constituted comparison sequence, the grey correlation sequence was bearing branch number> fruit number per branch> plant height> fruit weight> annual branches> crown breadth. Taking the ideal variety as the reference sequence, and the other varieties were compared ones, the grey correlation sequence was‘Baldwin’>’Powderblue’>’Brightwell’>’Premier’>’Climax’>’ Gardenblue’>’Homebell’>’Tifblue’. So, ‘Baldwin’, ‘Powderblue’, ‘Brightwell’ and ‘Premier’ are screened out, which have excellent comprehensive characters and are suitable for planting in Lijiang.
