Abstract:
Six genotypes of different maturity groups along with checks were screened against whipsmutdisease and borer pest underartificial and natural field condition during season2021- 22 to identify sources of disease and pest resistance. Eight entries designated viz., PDN 18005, PDN 18014, PDN 18016, PDN 18022, PDN 18025, CoM 0265, Co 86032 and CoC 671 exhibited resistant reaction whereas, 03 entries viz., PDN 18008, Co 7219 and Co 7527 genotypes exhibited moderately susceptible in their reactions to smut disease under artificially inoculated conditions in the field. Susceptible checks Co 740 had susceptible reaction indicated much disease pressure with susceptible reaction. Based on the incidence all the test genotypes recorded less susceptible reaction to early shoot borer. In case of incidence of internode borer, genotype CoM 0265, observed moderately susceptible and remaining genotypes showed highly susceptible reaction to internode borer. The incidence of top shoot borer was not seen throughout the crop season and eventually showed less susceptible reaction. These resistant germplasm may be further utilized as donor for further breeding programs to evolve new resistant variety against whip smut and borer pests of sugarcane.
