“…Thereby, we propose that the indica-japonica hybrid rice would be the ideal cultivar type (based on grain yield) for identifying the late-season japonica rice varietal traits. Although the inbred japonica varieties tested here had inferior yield behavior, Chen et al (2017) evaluated a series of inbred japonica varieties and determined that the grain yield of inbred japonica varieties was 10.00 ± 0.21 t ha −1 , which did not differ significantly from the indica varieties (9.40 ± 0.96 t ha −1 ). Furthermore, in the current study, the Nanjing46 variety had a grain yield of 7.3 t ha −1 during the 2016 late season, which was comparable to the grain yield of the elite indica rice in the late season (Huang et al, 2018).…”

It is unknown whether japonica rice bred up in the single season is suitable for growing in the late season in southeastern China. To evaluate the response of grain yield and growth traits of japonica varieties to the changing growing season, two types of japonica rice (inbred japonica and indica‐japonica hybrid rice) were planted during single and late seasons in 2016 and 2017. The grain yields of indica‐japonica hybrid rice were 8.3–9.5 t ha−1 and 9.2–10.8 t ha−1 in the late and single season, respectively, which were significantly greater than those of japonica inbred rice. In addition, the grain yields decreased when the growing season was switched from the single to the late season, being 17.3–23.7% for the inbred japonica rice and 4.0–9.7% for the indica‐japonica hybrid rice, indicating a small yield gap between the single and late season of the indica‐japonica hybrid rice. Furthermore, the indica‐japonica hybrid rice had a higher accumulated biomass, leaf area index (LAI), and spikelets per panicle; comparable phenological traits and leaf photosynthetic rate during panicle development; but lower grain weight and grain filling percentage compared with those of the inbred japonica rice. These results suggested that high grain yield of the indica‐japonica hybrid rice during the late season might be attributed to the high accumulation of biomass and the large panicle size. Thereby, we suggested that the great LAI during panicle development, high biomass accumulation before heading, and large panicle size might be useful as indicators for breeding the japonica variety during the late season.

“…In this study, the cooking and eating quality of rice was scored by the STA1A taste analyzer, a more objective evaluation of rice cooking and eating quality. The negative correlation between the rice grain yield and the cooking and eating quality was widely reported in the existing literature [39][40][41][42]. For example, Chen et al [39] observed that rice with a higher yield performance often produced the poor palatability of cooked grains in late-season cropping systems in central China.…”

For example, Chen et al [39] observed that rice with a higher yield performance often produced the poor palatability of cooked grains in late-season cropping systems in central China. Over recent years, special attention has been paid to grain quality, particularly cooking and eating quality in breeding programs in China, in addition to grain yield; such a breeding target was achieved mainly by lowering the amylose content of grains [7].…”

Understanding the agronomic and physicochemical characteristics related to grain yield and grain quality is an ongoing hotspot. In 2018 and 2019, high-yielding rice with good palatability (HYGP), high-yielding rice with poor palatability (HYPP), and low-yielding rice with good palatability (LYGP) were grown in paddy fields to explore the main traits underlying the better grain yield and overall palatability of HYGP. HYGP and HYPP demonstrated a 18.1–20.7% higher grain yield (p < 0.05) than LYGP; HYGP and LYGP gave an overall palatability from 75.2 to 77.0, higher (p < 0.05) than HYPP. The higher grain yield of HYGP compared to that of LYGP resulted from a larger sink size because of the spikelets per panicle and the higher total shoot biomass weight (p < 0.05). HYGP exhibited more (p < 0.05) panicles per m2 but lower spikelets per panicle and 1000-grain weight than HYPP and maintained a similar grain yield to HYPP. Compared with HYPP and LYGP, HYGP exhibited more (p < 0.05) biomass accumulation from heading to maturity, supported by the higher leaf area index, post-heading leaf photosynthetic rate, and SPAD values. HYGP had higher (p < 0.05) adenosine diphosphate glucose pyrophosphorylase and starch branching enzyme activities at the middle and late grain-filling stages than HYPP and LYGP. HYGP and LYGP had a lower (p < 0.05) chalky area, chalky degree, amylose content, setback, grain protein content, and prolamin content than HYPP, while it had a higher (p < 0.05) gel consistency, breakdown, and ratio of glutelin content to prolamin content. Our results suggested that optimized yield components, more biomass accumulation through improved leaf photosynthetic capacities, a lower amylose content with coordinated enzyme activities involved in starch synthesis, and a lower grain protein content with a better composition were the main traits facilitating the better grain yield and overall palatability of rice in east China.
