In breeding a new variety of sweet corn for Fujian, various maize germplasms were introduced, screened and selected according to the specific climatic and ecological requirements for the region. Mintian 4, a cross between the parents, Mintianxi 138 and Mintianxi 186, displayed a high combining ability and desirable complementary results in crop characteristics. During the 2009 — 2010 regional field trials, it exhibited an average yield of 14 445. 9 kg · hm-2 (I. E. , an increase of 14. 76% over CK), as well as the desirable properties on yield, quality, stability and adaptability. As a result, Mintian 4 had passed the provincial evaluation in 2012.%根据福建省气候、生态特点,引进各类甜玉米种质资源,通过筛选鉴定出适合福建省生态的甜玉米资源,利用系谱选育和配合力测定相结合的技术路线,育成新组合闽甜4号.测交试验表明,亲本闽甜系138、闽甜系186配合力高,性状互补性强,配成的闽甜4号表现高产、优质、适应性广、稳产性好,2009～2010年区试平均产量14 445.9 kg·hm-2,比对照增产14.76％,于2012年4月通过福建省农作物品种审定委员会审定.
