植酸（肌醇六磷酸）是磷在种子中的主要贮存形式，被认为对营养品质有负面影响。由于低植酸育种已被提议用于几种谷物和豆类，因此预测针对植酸的选择对其他主要谷物成分的影响是重要的。研究了两种冬小麦（Triticum aestivum L.）群体，每个群体由双杂交的F ×后代组成。观察到植酸P的显著变化，其值的范围等于相应群体平均值的30%和48%。观察到的植酸P的变化是高度和正相关的变化，在粮食总P（r 0.93和0.96，分别在人口1和2），并与粮食蛋白质的变化（r = 0.65和0.87，分别）。植酸磷与全磷和蛋白质的剂量相关性表明，对籽粒植酸的选择将导致籽粒全磷和蛋白质的不希望的减少。这项研究得到了明尼苏达州农业实验室的部分支持。STN.蒙大拿农业进出口公司STN.期刊编号J-2494。
Phytic acid (myo-inositol hexakisphosphate), the major storage form of P in seeds, is believed to have a negative impact on nutritional quality. Since breeding for low phytic acid has been proposed for several cereals and legumes, it is important to predict the effects of selection against phytic acid on other major grain components. Experiments were conducted to determine the quantitative relationship between grain phytic acid P, total P, and protein in two winter wheat (Triticum aestivum L.) populations, each consisting of F₆ progeny of a double cross. Substantial variation in phytic acid P was observed, with the range in values equal to 30 and 48% of the respective population mean. Observed variation in phytic acid P was highly and positively correlated with variation in grain total P (r 0.93 and 0.96 in Populations 1 and 2, respectively), and with variation in grain protein (r = 0.65 and 0.87, respectively). The dose correlation of phytic acid P with both total P and protein indicates that selection against grain phytic acid would lead to undesirable reductions in both grain total P and protein.
