Performance of pearl millet (Pennisetum glaucum L.) hybrids and their parents (B and R - lines) under rain fed & irrigated situations

A field experiment was conducted during kharif seasons of 2016 and 2017 at the Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar, India to study the "Performance of pearl millet (Pennisetum glaucum L.) hybrids and their parents (B and R - lines) under rain fed & irrigated situations". Six pearl millet hybrids and their parental lines i.e., B-Lines and R-Lines were grown under rain fed and irrigated environment. The grain yield was obtained higher in hybrid HHB 197 (30.33 q ha(-1)) under rain fed environment and in HHB 223 (37.36 q ha(-1)) under irrigated situation, whereas, among B-Lines, these values were maximum in ICMB 94555 and in R-Lines AC 04/13 under both of the environments. More growing degree days, photo thermal units and helio thermal units were exhibited by crop under irrigated environment than rain fed situation. Among hybrids better values of these parameters were exhibited by HHB 197 (1436.2 degrees C day, 18311.9, and 10068.8 degrees C day hour) and HHB 223 (1481.7 degrees C day, 18819.1 and 10342.7 degrees C day hour) under rain fed and irrigated environments, respectively. Among R-Lines, these parameters were maximum in AC 04/13. It is clear from meteorological parameter, that more GDD, PTU and HTU were accumulated and better RUE and HUE in the crop were recorded under irrigated environment than rain fed situation thereby resulting in more yield.
