摘要
1983～1986年对不同熟期的600余份试验材料,测定玉米成熟期籽粒含水量,研究分析果穗性状与籽粒含水量的关系。结果表明,在黑龙江省自然气候条件下,选育产量高、含水量低的杂交种,应该是穗轴细、穗粗适中、籽粒偏硬或中间型、长籽粒、单穗粒重和百粒重均高的杂交种。
More than 600 maize single and three-way crosses varying in maturity period were studied under the climate of Heilongjiang province. The results indicated that, a maize hybrid with high yield and low moisture content should posses the following ear characters: moderately thick ear diameter, thin ear cob, flint or medium-hard kernel type, long kernal, high ear weight and high 100 kernal weight et. al.
