A field experiment was conducted during the two winter seasons of 2007/2008 and 2008/2009 to evaluate the yield and its components, milling, technological and rheological characteristics as well as the correlation between these characteristics of eight bread wheat (Triticum aestivum L.) cultivars (Gemmeiza 7, Gemmeiza 9, Gemmeiza 10, Sakha 92, Sakha 93, Sakha 94, Giza 164 and Giza 168). These cultivars were chosen because they were new.
Gemmeiza 10 was shown to have the highest number of tillers and spikes per square meter, number of grains per spike and grain yield per hectare, followed by Gemmeiza 9, Giza 168, Sakha 94, Sakha 93, Sakha 92 and Giza 164. However, Gemmeiza 7 had highest biological yield per hectare, fine and coarse bran, protein, and wet and dry gluten percentages as well as farinograph properties. Giza 168 canopies were the tallest and also the straw yield was the highest. Also, Sakha 93 surpassed the other tested varieties in harvest index, flour and carbohydrate percentages. There are highly significant and positive correlations between each of grain yield per hectare and most of its components. The correlation between each of grain yield per hectare, flour and total carbohydrate percentages and dough weakness was found to be significant and positive. However, there was a negative correlation between each of grain yield per hectare, protein, gluten and bran percentages and farinograph properties.
Gemmeiza 10 cv. surpassed in yield factors and most of its components. However, Gemmeiza 7 cv. gave the highest values of grain and flour quality. On the other hand, the highest total carbohydrate and flour percentages were obtained from Sakha 93 cv.
本田间试验于 2007/2008 年和 2008/2009 年两个冬季进行，旨在评估 8 个小麦品种（Gemmeiza 7、Gemmeiza 9、Gemmeiza 10、Sakha 92、Sakha 93、Sakha 94、Giza 164 和 Giza 168）的产量及其构成、碾磨、工艺和流变特性，以及这些特性之间的相关性。选择这些品种是因为它们是新品种。
Gemmeiza 10 的每平方米分蘖数和穗数、每穗粒数和公顷产量最高，其次是 Gemmeiza 9、Giza 168、Sakha 94、Sakha 93、Sakha 92 和 Giza 164。然而，Gemmeiza 7 的公顷生物产量最高，粗粉和细粉、蛋白质、湿面筋和干面筋百分比以及粉质仪特性也最高。Giza 168 的冠层最高，秸秆产量也最高。此外，Sakha 93 在收获指数、面粉和碳水化合物百分比方面超过了其他测试品种。公顷产量及其大部分构成之间存在高度显著的正相关关系。公顷产量、面粉和总碳水化合物百分比与面团强度之间的相关性显著且为正相关。然而，公顷产量、蛋白质、面筋和麸皮百分比与粉质仪特性之间存在负相关关系。
Gemmeiza 10 品种在产量因素及其大部分构成方面表现优异。然而，Gemmeiza 7 品种的谷物和面粉质量最高。另一方面，Sakha 93 品种的总碳水化合物和面粉百分比最高。
