摘要: 为建立鉴定水稻孕穗期耐冷种质资源的生化指标,以云南孕穗期耐冷标准品种昆明小白谷、丽粳2号和半节芒及粳稻近等基因系(十和田4//丽江新团黑谷/十和田)的BC4F8、BC4F9群体105个家系及亲本为材料,在大田冷水胁迫及正常温度条件下,连续在2011年和2012年于水稻孕穗期分别测定剑叶、花药和籽粒的26个生化性状,采用主成分分析、隶属函数法、逐步回归分析和K-means聚类法进行指标筛选及耐冷性综合评价。结果表明,剑叶中叶绿素a、叶绿素b、总叶绿素、叶绿素c、POD活性、游离氨基酸,以及剑叶和花药中可溶性蛋白、可溶性糖、丙二醛、CAT活性、抗坏血酸、游离脯氨酸和籽粒中可溶性蛋白、可溶性糖、蛋白质和γ-氨基丁酸含量对耐冷性影响显著,可作为穗期耐冷性鉴定综合指标。采用隶属函数法获得低温胁迫下以剑叶、花药和籽粒中各生化性状为对象的综合耐冷D值,用K-means聚类法对各D值进行联合聚类,可将丽江新团黑谷NILs的105个株系划分为3类,其中强耐冷株系32株,中度耐冷10株,弱耐冷63株。

Abstract: The biochemical evaluation system were established for screening and identifying species with cold tolerance,105 rice materials,including three standard varieties of strong cold resistance from Yunnan Province,the NILs BC4F8 and BC4F9 generation derived from parents japonica cultivars Lijiangxintuanheigu(donor parent) and Towada(recurrent parent),and their parents,were employed for evaluation of cold tolerance and screening of cold resistance index at booting stage.26 biochemical traits including leaves,anthers,and grains of tested materials were determined under cold water-stress and normal conditions in 2011,2012.Comprehensive assessment of cold resistance based on the principal component analysis,subordinate function values analysis,regression analysis and K-means clustering analysis.The results showed Chlorophyll a,Chlorophyll b,total Chlorophyll,Chlorophyll c content,peroxidase(POD) activity,free amino acid content of flag leaves;soluble protein,soluble sugar,malondiadehyde(MDA) content,catalase(CAT) activity,ascorbic acid(ASA),proline content(Pro) of flag leaves and anthers;soluble protein,soluble sugar,protein,γ-aminobutyric acid(GABA) content of grains significantly influenced the cold resistance.Thus could be used as comprehensive index for identification of cold resistance at the booting stage.The values cold resistance comprehensive evaluation(D) of biochemical traits including leaves,anthers,and grains of tested materials based on the subordinate function values was chosen as object under cold stress condition,through K-means clustering analysis,105 lines of population should be divided into 3 categories including stongly cold-tolerant lines 32,mediate cold tolerance lines 10,and cold-sensitive lines 63.

Key words: Rice, Near-isogenic lines, Cold tolerance at booting stage, Biochemical identification index, Principal component analysis, Comprehensive evaluation
