| Description |
Twenty five genotypes of okra, Abelmoschus esculentus (L.) Moench were evaluated during crop season 2009-10 and twenty two genotypes were evaluated during crop season 2010-11 for field resistance to two spotted mite Tetranychus urticae Koch. On the basis of observation on incidence of T. urticae, seven genotypes namely, two least susceptible (HB-02-14-1-1 and HB-02-17-1) and two moderately susceptible (HTB-1-17-5 and HRB-107-4-1), two highly susceptible (HBT-6-15-3-7 and BB1) and one popular variety Hisar Unnat were selected for elaborate studies under field and laboratory conditions. During crop season 2009-10 two least susceptible genotypes of okra HB-02-14-1-1 (24.19/cm2)and HB-02-17-1(27.21/cm2) differed significantly (P |
