Two wheat cultivars, strong-gluten Yumai66 and medium-strong-gluten Yumai49, were usedto test the effects of irrigation and nitrogen application regimes on cooking quality ofChinese noodle in 2001-2002. The results showed that both in Yumai49 and Yumai66, valueof total organic matter (TOM) of noodle and noodle cooking loss rate ranked the firstwhile noodle score (NS) ranked the lowest in treatments without any nitrogen application.As nitrogen application rate increased, TOM value decreased but NS increased. The lowestTOM and the highest NS existed for treatments with 225 and 150 kg N ha-1 in Yumai49 andYumai66, respectively. Increasing irrigation resulted in greater TOM and NS, but lessbroken noodles. However, no significant difference was found in NS among differentirrigation treatments. Significant difference was found in TOM, NS, breaking rate andwater absorption rate of noodle between these two cultivars. Yumai49, with an average TOMvalue of 1.19 g and NS of 88.5, was better than Yumai66, with an average TOM value of1.55 and NS of 85.7. Interaction in TOM value was found between irrigation and nitrogenapplication. Effects of nitrogen fertilization were greater than that of irrigation inYumai49, while in Yumai66 the other way round. It is suggested, therefore, thosedifferent irrigation and nitrogen application regimes be chosen in production practicebased upon cultivar quality traits.
