摘要
采用灰色关联度多维综合评估法,以正大619为对照,对泰国引进的12份玉米群体的产量、容重、千粒重、出籽率、株高、穗位高、穗长、穗粗、穗行数、行粒数、秃尖长、病害等级和生育期等13个农艺性状进行综合评估,结果表明12份泰国玉米群体加权关联度大小顺序为NST05101F2>NST05201F2>SWS00352-2###>NP99201(RRS)C1F2>NST05103F2>NST05202F2>SW3(S)C4>NS1>NP99202(RRS)C1F2>SWS003Y-5###>NST05102F2>NST05203F2;加权关联序与产量位序说明玉米群体NST05101F2和NST05201F2较其他群体好。然而,在实际育种中这2个群体是否比其他群体更具有育种利用潜力有待进一步验证。
The present study was an attempt to comprehensively evaluate 13 agronomic traits（yield,unit weight,thousand-grain weight,kernel production rate,plant height,ear position,ear length,ear width,ear rows,grains per ear,bald length,disease level and growth period） of 12 introduced Thai corn populations by using grey relation analysis and Zhengda 619 was taken as control.The order of weighted grey relational degree was as follow： NST05101F2 NST05201F2 SWS00352-2### NP99201（RRS）C1F2 NST05103F2 NST05202F2 SW3（S）C4 NS1 NP99202（RRS）C1F2 SWS003Y-5### NST05102F2 NST05203F2.The order of weighted grey relational degree and yield indicated that the comprehensive agronomic traits of Thai corn populations of NST05101F2 and NST05201F2 were better than that of the other 10 Thai corn populations.However,the breeding potential of population NST05101F2 and NST05201F2 was needed to be further confirmed.
