Abstract:

This study aimed to select summer millet varieties suitable for planting in Kashgar of Xinjiang and provide a new comprehensive evaluation method for millet varieties screening. The DTOPSIS method based on entropy weight was applied to comprehensively evaluate 5 millet varieties planted in Kashgar, Xinjiang. 11 characters including yield, growth period, plant height, spike length, grass weight per plant, single spike weight, grain weight per spike, 1000-grain weight, milling ratio, lodging-resistance, Pyricularia setariae were selected for the evaluation. The results showed that the lodging resistance and Pyricularia setariae of millet varieties had great influence on the comprehensive evaluation of millet varieties, and the weights were 0.6191 and 0.2327, respectively. ‘Yugu18’ and ‘Jizajinmiao’ ranked first and second, but the yield of ‘Yugu 18’ was significantly lower than other varieties, ranking last, and ‘Jizajinmiao’ ranked third. ‘Jizajinmiao’ (0.7468) has stable comprehensive traits and good yield of 3906.75 kg/hm2, which is suitable for multiple cropping in Kashgar, Xinjiang, replacing ‘Yugu18’.

Key words: Kashgar, summer millet, DTOPSIS method, entropy, comprehensive evaluation
