摘要
利用从初步确定的黑龙江省主要玉米种质四大优势类群中各选取２个自交系，按Ｇｒｉｆｆｉｎｇ模式配制得到２８个双列杂交种，并用这８个自交系与其它类群的３个自交系按ＮＣ－Ⅱ设计进行不完全双列杂交，得到 ２４个杂交组合。试验结果表明，长 ３群× Ｍｏ１７群为长穗、大粒、熟期适宜类型，是适于黑龙江省生态条件要求的杂优模式。Ｍｏ１７群×唐四平头群为大穗、大粒型、中晚熟杂种优势利用模式。长３群×红玉米群为稳产、早熟杂种优势利用模式。长３群×唐四平头群及甸 １１×唐四平头群、吉 ８１８ × Ｍｏ１７群具有较高的产量杂种优势，目前生产上无这几种杂优模式品种应用，值得进一步研究。
inbred lines from each of four heterosis groups of heilongjiang majior maize germplasms were crossed in Griffing 4 design, and we got 28 hybrids. At the same time , the 8 inbrid lines were crossed with 3 inbrid lines from other group in NC - 2 design, and got 24 hybrids. Tlie results show that the model of ChangS × Mol7 are long earsN big grains and adapt maturity. It is a suitable cross model for heilongjiang province . The model of Mol7 × Tangsipingtou is big ears N big grains and mid - late maturity. Hie model of Chang3 × Hongyumi is good yield and early maturity. The models of ChangS × Tangsipingtou ^ Dianll × Tangsipingtou and JI 818 × Mol7 have high heterosis in yield. But these models were seldom used in maize production.
