Abstract:

The research was conducted during kharif 2016 at CCSHAU, Hisar. Transgenic cotton RCH 650 BGII and variety H 1098 i was evaluated for their reaction to cotton leafhopper under unsprayed condition. Observations on cotton leafhopper were recorded at weekly intervals. The highest population of leafhopper was recorded during 33rd standard week on RCH 650 BG II and 32nd standard week on H 1098 i. Leafhopper population were significantly and positively correlated with relative humidity while negatively correlated with temperature on both RCH 650 BG II and H 1098 i. Multiple regression analysis indicated that morning relative humidity alone accounted for 39 per cent variability in leafhopper population on RCH 650 BGII and 40 per cent variability in leafhopper population on H 1098 i, while evening relative humidity accounted for 34 per cent variability in leafhopper population on RCH 650 BGII and 37 per cent variability in leafhopper population on H 1098 i. Minimum temperature, wind speed, rainfall and number of rainy days influenced very less (< 16 %) on leafhopper population.
