摘 要: | 1993 ~1994 年以5 个组合的F1 ,F2 及其相应亲本为材料,在北京、石家庄和临汾三种环境条件下进行小区试验。结果表明,F1 和F2 在不同环境下均较其亲本表现出较高的产量和更好的稳定性。由于基因型与环境互作,某些F2 杂种在特定环境下表现出明显的杂种优势和超亲优势。某些F2 杂种较亲本可增产10 % 以上,在生产上具有一定的实用价值

Abstract: | The experiment adopted five F 1 and five F 2 hybrids as well as their corresponding parents. These materials were evaluated in three environments, i.e. Beijing, Shijiazhuang and Linfen in 1993 and 1994. The results indicated that both F 1 and F 2 hybrids perform higher yield and better stability in all environments than their parents. There exists significant interaction between genotype and environment, some F 2 hybrids increase yield by 10% than midparents. F 2 hybrid heterosis has practical value of commercial uses. |
