| 摘 要： | 为了解陕西小麦品种控制多酚氧化酶(Polyphenol oxidase,PPO)活性的主效基因组成.利用PPO 18和PPO 29标记时138份推广品种的PPO-2A和PP(9-2D位点的等位变异进行了分子检测.结果表明,在PPO2A住点,含Ppo-A1a(高PPO活性)和Ppo-A1b(低PPO活性)等位变异类型的品种比例分别为47.1%和52.9%;在PPO2D位点含PpoD1a(中等低PPO活性)和PpcrD1b(中等高PPO活性)等位变异类型的品种频率分剐为30.4%和69.6%;含Ppo-A1a/Ppo-D1a(较高PPO活性)、PpoAla/PpoD1b(最高PPO活性)、Ppo-A1b/Ppo-D1a(最低PPO活性)、Ppo-A1b/Ppo-D1b(较低PPO活性)等住变异组合类型品种的频率依次为10.1%、37.0%,20.3%和32.6%;不同地区不同等位变异类型及其组合的分布比例也不同.总体来看,陕西低PPO活性的小麦品种比例偏低,选育低PPO活性品种应成为当前陕西小麦品质改良的主要目标之一.

| Abstract: | Colour is an important trait exerting significant influences on the appearance of wheat-based products.In order to investigate content of polyphenol oxidase(PPO) activity and presence of allelic variations at PPO-2A and PPO-2D loci in Shaanxi wheat cultivars,a total of 138 cultivars were investigated using functional markers of PPO 18 and PPO 29.The results indicated that the frequencies of cultivars with alleles Ppo-A1a(high PPO activity),Ppo-A1b(low PPO activity) at PPO-2A locus were 47.1% and 52.9%,respe... |
