摘要

Five white kernel maize inbred lines were crossed in a complete diallel fashion during spring season 2010 at Cereal Crops Research Institute (CCRI), Pirsabak - Nowshera, Khyber Pakhtunkhwa, Pakistan. The resulting 20 F 1 hybrids, five parental inbred lines and two checks (OPV 'Jalal' and 'Pioneer hybrid 30k08') were evaluated in field experiments during summer season 2011 at four different locations i.e., Cereal Crops Research Institute (CCRI), Nowshera, University of Haripur, Haripur, Agriculture Research Station (ARS), Baffa - Mansehra, and Agriculture Research Institute, Mingora - Swat, Khyber Pakhtunkhwa, Pakistan. All the experiments were laid out in a randomized complete block design with three replications with the objective to identify the suitable hybrid combinations on the basis of their genetic potential for commercial cultivation in Khyber Pakhtunkhwa. A Large number of F 1 hybrids revealed significant positive heterotic effects for grain yield and most of the yield contributing traits at Swat, followed by Baffa, Mansehra, Haripur and CCRI, Nowshera. Majority of the F 1 hybrids revealed significant positive mid and better parent heterotic effects for ear length, grain rows per ear, 1000-grain weight and grain yield at all the locations. For grain yield, F 1 hybrids like PSEV3 × FRHW-1 and PSEV3 × FRHW-2 at CCRI, FRHW-2 × FRHW-1 and SWAJK-1 × FRHW-1 at Haripur, FRHW-1 × SWAJK-1 at Mansehra and FRHW-2 × FRHW-3 and FRHW-1 × SWAJK-1 Mingora, Swat showed desirable and significant positive mid and better parents, economic and commercial heterosis. Therefore, these F 1 hybrids could be reliably recommended for cultivation in the tested locations and their use in the future breeding programs for developing high yielding maize genotypes.
