“…Wang et al [24] also observed a higher milling eiciency in LYPJ than in an ordinary hybrid rice cultivar Shanyou 63 and they pointed out that the higher milling eiciency in LYPJ was associated its lower PCRG compared with Shanyou 63. In this regard, it is suggested that chalkiness reduces grain resistance to forces applied during the milling process, causing a decrease in milling eiciency [18,19].…”

“…Previous studies showed that the N application could increase milling eiciency and nutritional value (PC) in rice grains and there was a positive relationship between the PC and N application rate [20,23,24]. Furthermore, Wang et al [24] stated that the increased PC from the higher N application rate depended on increased TNU.…”

“…Recently, there has been a report describing the grain quality of a super hybrid rice cultivar Liangyoupeijiu (LYPJ) grown under diferent N rates [24]. Their results showed that LYPJ had higher HRP, AC and GC but lower PCRG and PC than an ordinary hybrid rice cultivar, Shanyou 63, across a wide range of N rates.…”

“…Furthermore, Wang et al [24] stated that the increased PC from the higher N application rate depended on increased TNU. However, in the present study, although the total N application rate was lower under SSNM than under FTNM by 20 and 15% in early and late season, respectively ( Table 2), no signiicant diferences were observed in N uptake (TNU and NUFG) in rice crops as well as milling eiciency and nutritional value in rice grains between SSNM and FTNM.…”

“…Ning et al [23] found that contents of four proteins (albumin, globulin, prolamin and gutelin) were increased with the increased N level in 31 japonica cultivars. Similarly, Wang et al [24] reported that PC increased with an increase in N rates in two hybrid rice cultivars and there was a signiicantly positive relationship between PC and the total N uptake (TNU) for each cultivar. The temperature, especially daily mean temperature during grain-illing period, is one of the dominant climatic factors afecting rice grain quality [25].…”

This study was conducted to determine the diferences in grain quality traits between super hybrid and popular inbred rice cultivars grown under two nitrogen (N) management practices. Field experiments were done at the Experimental Farm of Guangxi University, Guangxi Province, China in early and late rice-growing seasons in 2014. Two representative super hybrid cultivars Liangyoupeijiu (LYPJ) and Y-liangyou 1 (YLY1) and a popular inbred rice cultivar Huanghuazhan (HHZ) were grown under ixed-time N management (FTNM) and site-speciic N management (SSNM) practices in each season. Grain quality traits and N uptake were measured for each cultivar. LYPJ and YLY1 had higher milling eiciency, poorer appearance and palatability, and equal nutritional value than HHZ. The higher milling eiciency and poorer appearance in LYPJ and YLY1 were associated with their higher rice width compared with HHZ. Total N application rate was reduced by 15-20% under SSNM than under FTNM, whereas there was nearly no signiicant diference in grain quality between SSNM and FTNM. Our results suggest that (1) strategies for grain quality improvement in super hybrid rice should be focused on appearance and palatability, and (2) replacing FTNM with SSNM can reduce N input without sacriicing grain quality in rice production.

Background and ObjectivesThe effects of nitrogen (N) fertilization on rice quality, grain‐filling rate, and starch synthase activity have been widely studied, but whether there is a relationship between grain‐filling rate and starch synthase activity has not been reported. We conducted a 2‐year field experiment using the indica rice cultivar Shenliangyou 5814 to investigate the effects of N fertilization (0, 90, 180, 270, and 360 kg·ha–1) on rice quality.FindingsN fertilization notably increased grain yield, head rice rate, and protein content while reducing chalkiness degree and rate, thereby enhancing milling, appearance, and nutritional quality. Meanwhile, N fertilizer application (N = 270–360 kg·ha–1) delayed the time to reach the maximal grain‐filling rate, extending it to approximately 18.4–19.9 days after flowering, and enzyme activity also peaked around the same time. Grain‐filling rate was positively correlated with the activities of AGPase and SBE after N fertilization. They were also significantly correlated with milling, appearance, and nutritional quality after 22 days of flowering.ConclusionsN fertilization achieved a harmonious balance between the grain‐filling rate and starch synthase activities, ultimately improving milling, appearance, and nutritional quality.Significance and NoveltyN fertilization regulated the coordination between grain‐filling rate and starch synthase activity for rice quality.

BACKGROUNDNitrogen application is recognized as a principal factor influencing rice quality. However, there remains a paucity of research on the effects of different N levels on quality, particularly within the context of the improvement of rice varieties.RESULTSThis study examined 14 mid‐season japonica rice varieties cultivated in Jiangsu province over the past 80 years under five N application levels (0, 90, 180, 270, and 360 kg N ha−1). The results showed that yield increased steadily as varieties improved at all N levels. For varieties from the 1950s to the 1990s, yields initially rose and then declined as N application rates increased, peaking at 270 kg N ha−1. In contrast, modern varieties (post‐2000) exhibited a consistent increase in yield with higher N application rates. Fitted equations indicated that maximum yields were achieved at optimal N levels of 237–278 kg N ha−1 for varieties from the 1950s–1990s and 229.25 kg N ha−1 for post‐2000 varieties.As varieties improved, the content of brown, milled, and head milled rice, as well as albumen, gluten, and overall quality, increased. Conversely, chalkiness, protein content, gliadin and amylose content decreased, whereas gel consistency, breakdown, peak viscosity, and globulin showed no consistent pattern. Likewise, there was no consistent pattern in the tendency of starch to retrograde (as indicated by ‘setback’ values). Increasing N application rates enhanced the content of brown and milled rice, chalkiness, protein and its components, and the tendency of starch to retrograde (indicated by higher setback values). In contrast, amylose content, gel consistency, breakdown, peak viscosity, and overall taste quality declined with higher N levels.The study compared rice varieties with high yields (exceeding 10 t ha−1) and good comprehensive taste scores (above 52), revealing that modern varieties Wuyunjing 24, Lianjing 7, Yanjing 4038, and Nanjing 9108 performed exceptionally well with 180 kg N ha−1 and 270 kg N ha−1.CONCLUSIONModern varieties, with optimal N application and management, can achieve both high yield and good quality effectively. © 2024 Society of Chemical Industry.
