摘要
摘要:水稻品种的光能利用效率（RUE）是影响华南双季稻产量的重要因素之一。目前，关于品种的RUE特性及其与农艺性状间关系的研究鲜有报道。为此，本研究以华南双季稻区36个水稻主栽品种为供试材料，探讨了不同品种的RUE及其与产量等主要农艺性状的关系，并进行品种RUE类群的划分。结果表明，水稻的RUE在品种间和季节间的差异均达极显著水平；早、晚季的RUE均与稻谷产量、收获指数及千粒重等呈极显著正相关；早季的RUE与生物量呈极显著正相关、与生育期呈极显著负相关，晚季的则相关不显著。主成分分析结果表明，早季水稻品种特征主要由产量光能效率因子、穗粒因子、生育期粒重因子和结实率因子等4个主成分构成；晚季则主要由产量光能效率因子、穗粒因子、生物量因子、生育期粒重因子和结实率因子等5个主成分构成。通过系统聚类分析将华南双季稻品种划分为低光效型、中光效型和高光效型3个类群。早季低光效型、中光效型和高光效型的品种数分别占供试品种数的50.0%、38.9%和11.1%；晚季的依次分别为27.8%、47.2%和25.0%。其中，‘Y两优143’‘特优524’‘天优3301’和‘特优3301’等4个品种被划分为早季高光效型品种，‘五优308’‘天优3618’‘五优163’‘五优376’‘天优998’‘天优华占’‘天优3301’‘广8优188’和‘Y两优305’9个品种被划分为晚季高光效型品种。本研究结果将对水稻种植区域的品种布局、高RUE品种的选育及其高效利用具有重要指导意义。

Abstract:Radiation use efficiency (RUE) of rice varieties is an important factor influencing grain yields of double-cropping rice in South China. However, there have been few studies of rice RUE and its relationship to agronomic traits. We conducted two-season field experiments to evaluate the RUE of 36 major rice varieties in a double-cropping rice region of South China. The relationships between RUE and the main agronomic traits (for example, yield) were explored, and the clustering analysis of tested varieties were classified. The findings revealed highly significant difference of RUE existed in different rice varieties and cropping seasons, respectively. In early and late seasons, RUEs were significantly and positively correlated with the grain yield, the harvest index, and the 1000-grain weight. In the early season, RUE was significantly positively correlated with the biomass and significantly negatively correlated with the growth period; however, in the late season, these correlations were not significant. Principal component analysis revealed the 12 agronomic traits of the tested varieties to be compressed to four independent comprehensive indexes, including the yield and light energy efficiency factor, the panicle and grain number factor, the growth period and grain weight factor, and the seed setting rate factor, in the early season; and to five independent comprehensive indexes, including the yield and light energy efficiency factor, the panicle and grain number factor, the biomass factor, the growth period and grain weight factor, and the seed setting rate factor, in the late season. Clustering analysis revealed that the varieties tested in this study could be divided into three groups:low RUE, medium RUE, and high RUE. Rice varieties numbers with low RUE, medium RUE, and high RUE accounted for 50.0%, 38.9%, and 11.1%, respectively, of the total numbers of tested varieties in the early season and for 27.8%, 47.2%, and 25.0%, respectively of the total numbers in the late season. 'Yliangyou 143' 'Teyou 524' 'Tianyou3301' and 'Teyou3301' were identified as high-RUE varieties in the early season, and 'Wuyou308' 'Tianyou3618' 'Wuyou163' 'Wuyou376' 'Tianyou998' 'Tianyouhuazhan' 'Tianyou3301' 'guang8you188' and 'Yliang you 305' were identified as high-RUE varieties in the late season in South China. In our study, the classification of RUE types for rice varieties has been reported for the first time. The findings will have important guiding significance for the variety layout in growing areas and both the breeding of high-RUE varieties and their efficient utilization.
