不同节水抗旱稻品种的产量和稻米品质差异
Differences in Grain Yield and Quality of Different Water-saving and Drought-resistant Rice Cultivars
摘要
Abstract
[Objective]The differences in grain yield and quality of 5 water-saving and drought-resistant rice cultivars planted in Guizhou mountainous areas were investigated to provide a theoretical basis for popularization and application of new water-saving and drought-resistant rice cultivars.[Method]The differences in yield,yield components,rice processing quality,rice appearance quality,nutritional quality,starch RVA profile characteristics,cooked rice quality and rice texture properties of 5 water-saving and drought-resistant rice cultivars(Hanyou 116,Hanyou 73,Hanyou 78,Hanyou 786 and Huyou 61 were systematically analyzed by a field experiment.[Result]The yield of 5 water-saving and drought-resistant rice cultivars ranged from 8 985.89 to 11 833.77 kg/hm2,and the yield of Hanyou 78,Hanyou 786,Hanyou 73 and Huyou 61 exceeded 10 000 kg/hm2.The rice processing and appearance quality of Huyou 61 was poorer.The rice protein content of Hanyou 116 and Hanyou 73 with a lower amylose content was 3.41%-10.57%and 2.24%-6.67%higher than other rice cultivars,respectively.The peak viscosity,thermal slurry viscosity,final viscosity and breakdown value of Hanyou 116,Hanyou 78 and Hanyou 786 decreased by 5.03%-12.94%,3.86%-9.19%,6.17%-16.86%and 0.78%-7.16%compared with those of Hanyou 73 and Huyou 61,respectively.The setback value and pasting temperature of Hanyou 116,Hanyou 78 and Hanyou 786 increased by 119.13%-161.76%and 0.52%-8.21%compared with those of Hanyou 73 and Huyou 61,respectively.The cooked rice appearance,taste and comprehensive evaluation scores of Hanyou 116,Hanyou 78 and Hanyou 786 decreased by 4.47%-10.27%,3.61%-9.32%and 3.13%-10.50%compared with those of Hanyou 73 and Huyou 61,respectively.The hardness,chewiness,gumminess,cohesiveness and resilience of Hanyou 116,Hanyou 78 and Hanyou 786 increased by 10.57%-28.46%,20.62%-39.66%,10.62%-32.20%,7.32%-20.00%and 9.09%-23.81%compared with those of Hanyou 73 and Huyou 61,respectively.[Conclusion]The water-saving and drought-resistant rice cultivar Hanyou 73 with the advantages of higher rice yield and superior comprehensive rice quality should be popularized in Guizhou mountainous areas.关键词
