Screening of different genotypes of spine gourd (Momordica dioica Roxb.) against fruit fly in northern hilly region of Chhattisgarh

Abstract

Seventeen genotypes of spine gourd were screened against cucurbit fruit fly (Bactrocera cucurbitae) under natural field conditions with the collaboration of AICRP Potential Crop at Research-cum-Instructional Farm of IGKV, RMD College of Agriculture and Research Station Ambikapur in northern hilly region of Chhattisgarh during kharif 2017-18. Among the all, none of genotype was performed free from fruit fly infestation. Only the genotype Indira Kankoda (IK-1) was recorded as “resistant” showing of 16.30 and 17.43 percent fruit infestation (on fruit number and weight basis). However, the genotype RMF-7-P-1 was assigned as “susceptible” with 51.06 and 53.00 percent infestation respectively.
