以浙江省1995年早籼稻品种区域试验6个试点参试品种碾磨品质测定结果为试验材料,用多元分析法探讨了糙米率、精米率、整精米率3个碾磨品质的品种(基因型)、地点、品种×地点互作效应和各效应内碾磨品质间的相关关系,进行了参试品种互作效应检验。分析结果表明,糙米率、精米率以品种效应为主,整精米率性状以环境效应最大。相关分析显示,糙米率、精米率呈较强正相关,糙米率、精米率与整精米率均无相关关系。参试品种互作效应检验显示,多数品种整精米率均存在基因型×地点交互作用,糙米率、精米率多数品种较稳定。
Abstract:The genotype,test site,genotype×site effects on brown rice rate,milled rice recovery and head rice recovery as well as the correlation coefficients between the milling qualities within various effects were approached by using multiple analysis method with the data collected from early season indica rice varieties tested in regional trial in Zhejiang Province.Results showed that brown rice rate,milled rice recovery were predominantly affected by genotype.While head rice recovery was mostly conditioned by environment effect.Correlation analysis displayed that there were positive correlation between brown rice rate and milled rice rate.However,no correlation between brown rice rate,milled rice recovery and head rice recovery was found.The analysis of genotype×site of the varieties tested displayed that head rice recovery of the most tested varieties is involved with the interaction effects between the two components,while brown rice rate,milled rice recovery of the most tested varieties were more stable. 相似文献

浙江省早籼稻区试品种(系)碾磨品质研究 总被引:5,自引:0,他引:5
本文对水稻区域试验中多品种(系)、多年、非平衡、无重复分析值的品质性状资料提出相应的统计分析方法,并对早籼稻区试品种(系)碾磨品质作了统计分析.分析结果表明,91—94年期间参试的早籼稻品种(系)其糙米率、精米率较“七五”期间参试的品种(系)有显著提高,金89—1、中选2号、浙733品种(系)的糙米率、精米率都显著或极显著的高于对照品种.三个碾磨品质中整精米率的方差较大,且变异主要来自于品种×年份的交互作用. 相似文献

二棱大麦农艺性状ADAA遗传模型的分析 总被引:4,自引:3,他引:4
以甘木二条等七个二棱大麦(HordeumdistichumL.)品种进行7×7双列杂交(无反交),对亲本、F_l和F_2熟期、产量、穗部、茎杆等18个农艺性状,采用加性─显性─上位性(ADAA)模型估算了各遗传方差占表型方差的比率,结果抽穗期等10个性状(占55.5%)存在加性×加性上位性效应,其中5个性状以上位性效应为主(占表型方差的35.4─54.96%).对有上位性效应的性状应以ADAA模型分析,如以传统的AD模型分析,所得的结论不真实.狭义遗传力在性状间有较大差异,以穗着粒密度最高(83.05%),单株产量最低(10.24%).杂种优势总方向预测表明,二棱大麦多数杂交组合具千粒重、穗长、每穗粒数、茎粗的正向大穗型杂种优势。此外,对有关性状进行了相关分析. 相似文献
