中文摘要:
      基于2013—2015年江苏粳稻参试品种(系)试验数据,分析了参试粳稻的产量水平、产量构成因子、品质性状等类型间差异及其相互关系。结果表明:江苏粳稻整体产量水平与株高、全生育期、结实率之间均达极显著正相关;有效穗数、穗粒数、结实率及千粒质量等产量因子与主要品质指标间相关性不显著,提高整体产量水平对于稻米的碾磨品质、外观品质及食味品质的影响较小;碾磨品质与外观品质、蒸煮食味品质各指标间相关性不显著,但蒸煮食味品质指标与外观品质指标间矛盾较为突出,直链淀粉含量与垩白粒率、垩白度间均呈极显著负相关关系(–0.423**、–0.682**),胶稠度与垩白粒率、垩白度间均呈极显著正相关关系(0.218**、0.404**)。综合以上结果认为,江苏粳稻产量水平与主要品质性状间矛盾不突出,可以在保持现有产量水平的基础上改进品质,同时平衡外观与适口性之间关系,选育出外观品质优、食味口感佳的优质、高产、稳产新品种(系)。
英文摘要:
      In this study, the differences of yield, yield components, quality traits and their relationships of Jiangsu japonica varieties were analyzed based on the data collected from the regional new rice varieties tests of Jiangsu in 2013–2015. There were very significant positive correlations between the yield and the plant height, the growth period and the seed setting rate of Jiangsu japonica rice. There were no significant correlations between the appearance quality traits and the number of effective spikes, grains per spike, seed–setting rate and 1 000–grain weight, suggesting that yield increase has little influence on processing quality, appearance quality or eating quality. The correlations between processing quality and appearance quality, cooking and eating quality were not significant; however, there was a prominent contradiction between appearance quality and cooking and eating quality, the chalky rice rate and chalkiness degree were significantly negatively correlated with amylase content (–0.423**and –0.682**) respectively, and significantly positively correlated with gel consistency (0.218** and 0.404**) respectively. The results indicated that there were no serious contradictions between yield and major quality traits of Jiangsu japonica rice varieties; it is feasible to improve rice quality without sacrificing yield, make a balance relationship between appearance quality traits and palatability, and breed new rice varieties of high–quality high–yielding and stable–yielding.
