Abstract:

Six large and eleven small fruit tomato cultivars were used as the experimental lines. Seven main characteristics of the introduced tomato cultivars were comprehensively analyzed and evaluated using grey correlation analysis, to identify cultivars with better overall quality and provide reference for promoting high-quality development and popularization of the local tomato industry. Among the six large fruit tomato cultivars, ‘GH-148’ and ‘Taste 2010’ showed stronger resistance to low and high temperatures. Grey correlation analysis revealed that the six large fruit tomato cultivars ranked in order of decreasing correlation degree were ‘Taste 2012’, ‘Taste 2011’, ‘GH-148’, ‘Taste 2010’, ‘Ziyu Heijiangjun’ and ‘Taste 2013’. Among the eleven small fruit tomato cultivars, ‘Lizi Tomato’, ‘Heizhenzhu’, ‘DH21002’, ‘DH21003’, ‘Zijingzhu’, ‘Zishengnv’, ‘Ziyi Xiannv’, and ‘Ziyu Xiaoxing Tomato’ showed stronger resistance to low and high temperatures. Grey correlation analysis revealed that the eleven small fruit tomato cultivars ranked in order of decreasing correlation degree were ‘DH21003’, ‘Ziyu Xiaoxing Tomato’, ‘Ziyi Xiannv’, ‘DH21002’, ‘Heizhenzhu’, ‘Zijingzhu’, ‘Lizi Tomato’, ‘Ziqianxi No.6’, ‘Qianxi’, ‘Ziqianxi No.9’ and ‘Zishengnv’. This study has preliminarily selected ‘Taste 2012’ as a suitable tomato variety for cultivation in Bazhou, Xinjiang, and ‘DH21003’ as a suitable small tomato variety.
