 ABSTRACT

An experiment was conducted to estimate the nature and magnitude of heterosis for grain yield, its components and quality traits in a diallel cross of eight genetically diverse wheat genotypes excluding reciprocals. Highly significant differences were observed among the genotypes for all the traits studied. Significant heterobeltiosis, average heterosis and standard heterosis was observed in the cross HI 1588 x MP 4080 with a value 39.64, 54.59 and 54.30, respectively over the check variety, GW 496 and it was adjudged best heterotic cross combination for grain yield per plant. The cross HD 2392 x GW 273 exhibited significant   positive standard heterosis for number of tillers per plant and spikelets per spike over the check. The cross UP 2669 x GW 273 exhibited highest and significant positive heterosis over better parent and mid parent for grains protein content. These crosses can be used in developing high yielding cultivar with good quality traits.
