Title	Combining ability estimates for yield and yield components in spring wheat
Journal	Sarhad Journal of Agriculture
Year	2004
Volume	20
Pages	485-487
Author	Muhammad S Shiraz A Malik MFA Awan SI
Abstract	The combining ability estimates in a 5x5 diallel cross of spring wheat cultivars Faisalabad 83, Faisalabad 85, Chakwal 86, Rawal 87 and Rohtas 90 were determined for days to heading, days to maturity, plant height, tillers per plant, spikelets per spike, grains per spike, 1000-grain weight and grain yield per plant in Fateh Jang, Pakistan, during 2000-01. The analysis of variance revealed highly significant differences for all traits. The specific combining ability variance was higher than the general combining ability variance for all the traits indicating non-additive gene action except for days to heading, days to maturity and plant height, which showed additive gene action. Grains per spike showed both additive and non-additive gene action. Faisalabad 83 and Chakwal 86 were good general combiners while Faisalabad 83 x Chakwal 86 was the best specific combiner
