Abstract
Host plant resistance is an important component of integrated pest management strategy for jassid resistance. Evaluation of germplasm to identify the stable source of resistance is a predominant step in any resistance breeding programme. In this study, screening of Gossypium hirsutum cotton varieties/genotypes against jassid, Amrasca biguttula biguttula (Ishida) was carried out under rainfed conditions during kharif seasons of 2016-17, 2018-19 and 2019-20 at Regional Cotton Research Station, Navsari Agricultural University, Maktampur farm, Bharuch, Gujarat. Among thirteen cotton varieties/genotypes screened, none of variety/genotype was categorized as resistant by considering jassid population as well as Jassid Resistance Index. Six cotton varieties/genotypes viz., NH-615, GBHV-201, GBHV-209, GBHV-204, G.N.Cot-26, GBHV-206 and two checks i.e. DHY-286 and NDLH-1938 were categorized as moderately resistant based on maximum jassid population ranged from 4.40 to 7.40 jassids/3 leaves. Three cotton varieties/genotypes viz., Suraj, Bunny BG II and Bunny Non Bt were categorized as susceptible with population of 12.50 to 13.70 jassids/3 leaves. The cotton variety G.Cot-16 (16.70 jassids/3 leaves) and check DCH-32 (24.60 jassids/3 leaves) were categorized as highly susceptible to jassids. Five cotton varieties/genotypes viz., NH-615, GBHV-201, GBHV-204, GBHV-209, G.N.Cot-26 and two checks i.e. DHY-286 and NDLH-1938 were categorized as moderately resistant based on maximum Jassid Resistance Index in range of 1.10 to 2.00. Only the genotype GBHV-206 was found susceptible with 2.20 JRI. Four cotton varieties/genotypes viz., G.Cot-16, Bunny BG II, Suraj, Bunny Non Bt and check DCH-32 were categorized as highly susceptible to jassid based on maximum JRI of 3.10 to 4.00. Overall five varieties/genotypes of G. hirsutum cotton viz., NH-615, GBHV-201, GBHV-209, GBHV-204 and G.N.Cot-26 were found moderately resistant to jassids under rainfed conditions.
