Due to wide genetic diversity, it has great untapped genetic potential for improvement as and when need arises. The present investigation entitled “Heterosis and combining ability studies in diallel crosses of maize (Zea mays L.)” which comprised of 21 single cross hybrids developed by half-diallel mating design involving 7 parents and 2 standard checks viz., (Gujarat Maize-3 and HQPM-1). The experiment was laid out in randomized block design with three replications at Agronomy farm, B. A. College of Agriculture, Anand Agricultural University, Anand during rabi season 2012-13. Heterosis, combining ability and components of genetic variance were studied for 13 characters viz; days to 50% tasselling, days to 50% silking, plant height, ear height, days to 75% dry husk, ear length, ear girth, number of grain rows per ear, number of grains per row, 100- kernel weight, grain yield per plant, shelling percentage and protein content.enagriculture, botanystudyThesis
