Inheritance of Plant Height, Days To Heading, Spike Length, Peduncle Length and Spikelets Per Spike in a Spring Wheat Cross

The gene action for plant height, days to heading, spike length, peduncle length and spikelets per spike was studied deploying parental, F1, F2, B1 and B2 generations of a cross of common wheat (WL 711 × HD 2009). The additive and additive × additive type of gene action was predominant for most of the evaluated attributes. The additive, dominance and dominance × dominance type of gene action was significant for spike length, peduncle length and spikelets per spike. The study of correlations revealed negative association between [h] and [1] parameters for all the meaured characters indicating a duplicate type of gene action operative for all of these traits. Possibilities of the breeding methodologies such as population improvement approach in the form of biparental matings coupled with recurrent selection and multiple breeding techniques have been suggested for making rapid advances for the developing of improved lines.
