摘要/Abstract

摘要：

杂交稻的籽粒产量通常高于常规稻，但其整体表现常受倒伏和米质差的影响。目前，针对常规稻和杂交稻中同时实现高产、优质和抗倒的品种性状探索较少。因此，本研究于2020年和2021年在华中地区开展田间试验，杂交稻和常规稻各选取了5个代表性水稻品种。结果表明，在2020年和2021年杂交稻的平均产量分别为8.01 t ha^-1和8.63 t ha^-1，较常规稻分别显著提高了10.3%和13.4%。杂交稻表现出与常规稻相当的米质和抗倒伏性。不同品种间在产量、米质和抗倒伏性状方面存在显著的基因型变异。在各品种类型中，鄂丰丝苗（常规稻）和晶两优534（杂交稻）表现出最为均衡且优异的农艺表现。与高产、优质和强抗倒伏性综合表现密切相关的关键性状包括：较高的单位面积颖花数、较低的籽粒长宽比和较短的基部节间。本研究结果表明持续选育综合性状优良的水稻品种是满足日益增长的粮食产量和品质需求的可行策略。

Abstract:

Hybrid rice generally showed higher grain yield than inbred rice, but its overall performance is largely affected by lodging and lower grain quality. Limited attention has been given to exploring genotypic variation and varietal traits for achieving high yield, superior quality, and strong lodging resistance simultaneously in both inbred and hybrid rice. To address this gap, field experiments with five representative rice varieties from each rice type were conducted in Central China in 2020 and 2021. The results showed that the average yield of hybrid rice in 2020 and 2021 was 8.01 and 8.63 t ha^–1, respectively, representing significant increases of 10.3 and 13.4% compared to inbred rice. Importantly, hybrid rice showed comparable grain quality and lodging resistance to inbred rice. Substantial genotypic variation was observed among the varieties for yield, grain quality, and lodging-related traits. Efengsimiao (inbred) and Jinliangyou 534 (hybrid) showed the most balanced and superior agronomic performance within each variety type. Key traits associated with the integration of high yield, superior quality, and strong lodging resistance included high spikelets per unit area, low grain length–width ratio, and short basal internode. These findings highlighted the potential to select and breed rice varieties that optimize multiple desirable traits, offering a promising strategy to meet growing food demands in both quantity and quality.
