Abstract:
The objective of this work was to characterize the accumulation of carbon (C) and nitrogen (N), and the translocation of wheat ( Triticum aestivum L.) cultivars to achieve both high-quality and high-yield. Twenty-four wheat cultivars, including 12 cultivars containing high-quality gluten subunit 5 + 10 at Glu-D1 , and 12 cultivars with no Glu - D1 5 + 10, were planted at Yuanyang and Xuchang in Henan Province, during 2016–2017, and 2017–2018 cropping seasons. Wheat cultivars containing Glu-D1 5 + 10 had an advantage in grain quality traits. Significant difference ( P 〈 0.05) was observed for grain protein concentration (GPC) between 5 + 10 group and no 5 + 10 group. Grain yield (GY) was significantly correlated with kernel number (KN) (r = 0.778, P 〈 0.01), thousand-kernel weight (TKW) (r = 0.559, P 〈 0.01), dry matter accumulation at post-anthesis (r = 0.443, P 〈 0.05), and stem water-soluble carbohydrate (WSC) accumulation (r = 0.487, P 〈 0.05) and translocation amount (r = 0.490, P 〈 0.05). GPC, dough stability time (DST) and nitrogen agronomic efficiency (NAE) were significantly correlated with nitrogen accumulation (NAA) at maturity stage (r = 0.524, = 0.404, = 0.418, P 〈 0.01, 〈 0.05, 〈 0.05, respectively), and nitrogen translocation amount (r = 0.512, = 0.471, = 0.405, P 〈 0.05, 〈 0.05, 〈 0.05, respectively). These results suggest that good-quality, high-yield, and high-efficiency could achieve through the selection of high-quality wheat cultivars and coordination of C and N accumulation and translocation. High-quality gluten subunit gene Glu-D1 5 + 10 and stem WSC could be used as a selection index for breeding and production of high-quality and high-yield wheat.
