摘要:
试验选用导入热带玉米种质选育的8 份自交系, 每份自交系选定2 个测验种, 对比法设计。结果表明:甸骨11A 导入Suwan1 、5-56 选系, a1 ×红玉米、a2 ×红玉米产量对照优势18 .9 %、9 .4 %;a1 ×早大黄、a2 ×早大黄产量对照优势均为负值。红玉米导入Suw an1 、EV T5 选系, b1 ×甸骨11A , b2 ×甸骨11A 产量对照优势14 .0 %、9 .4 %;b1 ×C500 、b2 ×C500 产量对照优势4 .8 %、12 .5 %。长3 导入Suw an1 、墨黄9 选系, c1 ×海014 、c2 ×海014 产量对照优势15 .8 %、9 .4 %;c1 ×龙抗11 、c2 ×龙抗11 对照优势-4 .0 %、6 .6 %。Mo17 导入Suw an1 、5-50 选系, d1 ×B73 、d2 ×B73 对照优势2 .0 %、-4 .6 %;d1 ×444 、d2 ×444 对照优势3 .8 %、12 .2 %。
