Abstract

This study was aimed to investigate baking quality of some bread wheat and water stress. A field experiment was carried out at the fields of the College of Agricultural Engineering Sciences - University of Baghdad during the seasons 2018-2019 and 2019-2020. Five local cultivars and 20 entrance genotypes were planted, during first season and the best 9 genotypes for baking ability were selected and tested in the second season, under moisture depletion levels of 50, 70, and 90% of field capacity, RCBD was used for the first season, with a split-plot design for the second season, with three replications for both seasons. The levels of moisture depletion occupied the main plots and the genotypes of the sub plots. In the second season, the results showed that reducing the moisture depletion to the level of 50% of the available water produced the highest grain yield, while the 90% moisture depletion level exceeded 90% produced the highest means of the protein%. It could be concluded that the availability of the appropriate quantities of irrigation water reflected positively on grain yield and that the decrease in the quantities of irrigation water improved protein%.

研究了几种面包小麦基因型在水分胁迫下的烘焙品质

对部分面包小麦的烘焙品质和水分胁迫进行了研究。在2018-2019和2019-2020季节，在巴格达大学农业工程科学学院的田野进行了实地试验。种植5个地方品种和20个进口基因型，第1季和第2季分别筛选烘焙性能最佳的9个基因型，在水分枯竭水平为田间容量的50%、70%和90%的情况下，第1季采用RCBD，第2季采用分块设计，2季3个重复。水分耗竭水平占主样区，亚样区基因型不同。第二季试验结果表明，减湿至有效水分50%时籽粒产量最高，减湿90%以上蛋白质%均值最高。综上所述，灌溉水的适宜用量对籽粒产量有正向影响，灌溉水用量的减少提高了籽粒蛋白质%。
