Abstract:

Screening of sixteen cotton varieties/genotypes against jassid, Amrasca biguttula biguttula (Ishida) was carried out under rainfed conditions during kharif seasons of 2015-16 and 2016-17 at Regional Cotton Research Station, Navsari Agricultural University, Maktampur farm, Bharuch, Gujarat. The results revealed that none of the cotton variety/genotype was totally free from attack of A. biguttula biguttula and categorized as resistant based on population of jassid. Eleven varieties/genotypes viz., G.Cot.-12, GSHV-01/1338, GISV-267, G.N.Cot.-22, GSHV-159, GISV-272, GBHV-177, GBHV-170, GBHV-180, GBHV-164 and G.Cot.-16 were designated as moderately resistant to jassid by recording the population ranged from 2.41 to 6.37 jassids/3 leaves. The susceptible cotton varieties/genotypes comprised G.Cot.-10, LRA-5166 and G.Cot.-100 which registered population ranged from 8.11 to 11.38 jassids/3 leaves. However, genotype Cocker-310 and GSB-21 were categorized as highly susceptible to jassid with population of more than 11.73 jassids/3 leaves. The highest seed cotton yield (2522 kg/ha) was recorded on moderately resistant genotype GISV-272. The seed cotton yield showed highly significant negative correlation with jassid population (r= -0.646).
