【摘要】 应用数量遗传学中的阈性状分析法,计算米象对甲酸乙酯的抗性现实遗传力,并对米象的抗药性风险进行了评估。结果表明,在平均死亡率为57.4%的选择压力下,米象对甲酸乙酯的抗性现实遗传力(h2)为0.0646,在此选择压力下要使米象对甲酸乙酯产生10倍的抗药性,共需要选育179代。更多还原

【Abstract】 The resistant risk of S.oryzae to ethyl formate(EtF)was assessed using the realized heritability(h 2) of quantitative genetics.The realized heritability of resistance of S.oryzae to EtF was 0.0646at the selection pressure while the 57.4% mortality.At the condition of this pressure,the selection of 179generations should be conducted if the resistance of S.oryzae to EtF amounted to 10fold.更多还原
