甜、糯玉米抗虫性的基因型差异

Genotype Difference of Insect-Resistance of Sweet and Glutinous Maize

田间调查了不同基因型甜玉米和糯玉米的花叶率 ,螟虫、粘虫和棉铃虫数量以及后期植株上的虫孔数、幼虫数、单株虫道长和产量。结果表明 :花仙子和白雪丽人的受害程度较轻 ,黑妹和白糯的受害程度较重 。

Field investigation on the rate of insect hole, quantity of maize borers and army worm and cotton bollworm,numbers of insect hole on the stem, numbers of larva and tunnel length in the stem,yield of 8 sweet and glutinous maizes with different genotypes showed that injury level of Huaxianzi and Baixueliren genotypes were lower and that of Heimei and Bainuo genotypes were higher than that of other genotypes.Huaxianzi got the highest yield.
