摘要： 泰国的玉米研究,农业合作部农业厅开始于1950年,大学部肯色萨大学开始于1958年。国家玉米和高粱研究中心,通称苏湾农场和农业厅大田作物研究所下属从事玉米研究的Nakhon Sawan大田作物研究中心,通称沙湾中心,分别成立于1965,1963年。著名的SW1于1969-1972年间选育成功,与SW1种源有高度配合力的广基综合种KS23于1987-1988合成,作为与KS23相配对的、相互轮回选择的广基综合种KS24,于1992-1993年合成。截至目前,已合成和改良了下列群体,硬粒型群体有SW2,SW3,SW5,Sawan-complex,NSDR;马齿型群体有KS6,KS27,CaripenoDMR,KS28,Pop.24,Pop.28。Ki21,Ki45,Kei0102等自交系则分别来源于Pacific 9,Pioneer 3013等。接着,在1982-2006年间发展和(或)应用了6个杂交利用模式,即SW1C4×SW1C4;SW1C4×Caripeno DMRC1;(SW1C4、C8,SW3C2、C3,KS6C2的选育系)×Mo17热带种质衍生系Ki21,Ki45;SW1×Pop.28;(SW1,non-SW1选育系)×优良杂交种Pioneer 3013二环系-Kei0102和KS24×KS23(即SW1×non-SW1)。

Abstract: Maize research in Thailand was init iated by the Department of Agriculture in 1950 and Kasetsart University in 1958. The National Corn and Sorghum Research Center, Farm Suwan was set up in oder to support theThai National Corn and Sorghum research program in 1965; The Nakhon Sawan Field Crops Research Center was established in 1963 to carried out research on corn aspect. The famous Suwan1 was formed in 1969- 1972, KS23 is a broad base Synthet ic developed in 1987- 1988 that have good combining ability with strains of Suwan1, KS24 is a broad base Synthet ic developed in 1992- 1993 which was designed to serve as a heterotic counterpart of KS23, as two populations of reciprocal recurrent selection Suwan2, Suwan3, Suwan5, Sawan-Complex, NSDR for flint type grain and KS6, KS27, Caripeno DMR, KS28, Pop. 24, Pop. 28 for dent type grain were developed.Ki21, Ki45, Kei0102 were developed from elite hybrid Pacific 9, Pioneer 3013 etc.Then, six main heterotic patterns were determined and(or) used in 1982- 2006. i. e. SW1(S) C4 SW1(S) C4; SW1(S) C4 Caripeno DMR(S) C1; (Inbred line from SW1(S) C4、C8, SW3(S) C2、C3, KS6(S) C2) Mo17 derivate line for tropical germplasm,Ki21, Ki45; SW1 Pop28; (SW1, non-SW1) recycled line from elite hybrid Pioneer 3013,Kei0102, and KS24 KS23(SW1 non-SW1).

Key words: Maize, Maize research and development, Heterotic group, Heterotic pattern, Germplasm development
