摘要
为了给戊聚糖在小麦品质改良中的利用提供参考,本研究以小麦杂交组合"郑麦9405/皖麦19"F2植株群体为试材,采用地衣酚-盐酸法分析了335个单株籽粒全麦粉的水溶性戊聚糖(WSP)和非水溶性戊聚糖(WIP)含量。结果表明,双亲郑麦9405和皖麦19的水溶性戊聚糖含量分别为1.25%和0.65%,非水溶性戊聚糖含量分别为6.25%和8.13%;F2代植株群体的水溶性和非水溶性戊聚糖含量的平均值分别为1.07%和5.97%,其中,水溶性戊聚糖含量大于高亲值(1.25%)和小于低亲值(0.65%)的分别有47株和2株,大于1.7%的有6株,非水溶性戊聚糖含量大于高亲值(8.13%)和小于低亲值(6.25%)的分别有6株和190株,高于8.50%和低于3.50%的分别有3株和5株。可见通过杂交可以在具有不同水溶性和非水溶性戊聚糖含量的亲本组合后代群体中筛选出高、低水溶性戊聚糖含量的育种材料,对小麦品质育种具有一定的实际意义。
The purpose was to provide a reference for pentosans in wheat quality improvement. The random population of F2 generation were selected as materials to test the water soluble pentosan （WSP） and waterinsoluble pentosan （WIP） contents with grain whole mills of 335 single plants in a wheat cross ＂Zhengmai 9405/Wanmai19＂ with Oreinol-hydrochloric acid method. The results showed that the WSP and WIP contents in parents Zhengmai 9405 and Wanmai 19 were 1.25%and 0. 65%, 6.25% and 8.13%, respectively. The mean of WSP and WIP contents with grains whole-mills in the population of F2 generation were 1.07% and 5.97%. Water soluble pentosan contents of 6 single plants were over 1.7% and WSP contents of 2 single plants were less than 0.65%. Water insoluble pentosan contents of 3 single plants were over 8.50% and WIP contents of 5 single plants were less than 3.50%. Therefore, the breeding materials of high or low WSP and WIP contents could be selected in the population of early generations of wheat cross which had the parents with various WSP and WIP contents.
