摘要:

为研究烤烟杂交种‘YY021’的烘烤特性及杂种优势,以‘YY021’及其母本‘MSY106’、父本‘LY1306’为研究对象,采用暗箱试验研究上部烟、中部烟和下部烟的变黄、变褐特性;采用电烤箱试验,研究中部烟烘烤过程中烟叶的失水特性、叶绿素降解特性和多酚氧化酶(PPO)活性变化,评价‘YY021’易烤性和耐烤性及其杂种优势。结果表明,上、中、下部位叶片变黄速率均表现为‘YY021’>‘LY1306’>‘MSY106’,下部和中部烟叶变褐速率表现为‘LY1306’>‘MSY106’>‘YY021’,上部烟叶变褐速率表现为‘LY1306’>‘YY021’>‘MSY106’。‘YY021’及其父母本变黄指数和变褐指数均随着叶片部位升高而减小。中部烟叶失水均衡性表现为‘LY1306’显著高于‘MSY106’,‘YY021’介于父母本中间,有中亲优势。‘YY021’中部烟叶绿素降解速率与父母本差异不显著,无杂种优势。中部烟PPO活性均值表现为‘MSY106’>‘YY021’>‘LY1306’,品种间差异显著,‘YY021’有中亲优势。综合上述各指标并参考生产实际表现,‘YY021’中部烟叶易烤性和耐烤性中等,有中亲优势,无超亲优势。

Abstract:

In order to study the curing characteristics and advantages of ‘YY021’, ‘YY021’ and its dam ‘MSY106’ and male parent ‘LY1306’ were used as test materials, and the yellowing and browning characteristics of the upper, middle and lower parts were studied by dark box test, and the water loss characteristics, chlorophyll degradation characteristics and polyphenol oxidase activity changes of the middle tobacco leaves were studied by electric oven test, and the hybrid advantages of easy curing and roast resistant of ‘YY021’ were evaluated. The results showed that the yellowing rate of the upper, middle and lower leaves was ‘YY021’>‘LY1306’>‘MSY106’, the browning rate of the lower and middle tobacco leaves was ‘LY1306’>‘MSY106’>‘YY021’, and the browning rate of the upper tobacco leaves was ‘LY1306’>‘YY021’>‘MSY106’. The yellowing index and browning index of ‘YY021’ and its parents decreased with the rise of leaf position. The balance of water loss in the middle tobacco leaves showed that ‘LY1306’ was significantly higher than ‘MSY106’, and ‘YY021’ was in the middle of the parents, which had the advantage of middle parenthood. The degradation rate of chlorophyll in the middle of ‘YY021’ was not significantly different from that of the parents, and there was no heterogeneous advantage. The average PPO activity of central leaves was ‘MSY106’>‘YY021’>‘LY1306’, with significant differences between varieties, and ‘YY021’ had the advantage of mesokinship. Based on the above indicators and production performance, the middle tobacco leaf of ‘YY021’ had medium easy curing potential and endurable curing potential, with the advantage of mesokinship, and no super-parent advantage.
