Hybrid breeding is a promising approach to increase the yield potential in wheat (Triticum aestivum L.). The profitability of wheat hybrids highly depends on a cost-efficient system for hybrid seed production for which an adequate outcrossing in the male pool is of utmost importance. Employing a set of 51 elite winter wheat lines, we developed and evaluated phenotyping methods for floral and flowering traits with relevance for improved cross-pollination. We observed significant genotypic variances and high heritabilities for most traits, including important traits like pollen mass and anther extrusion. Our results suggest the utility of the developed phenotyping approaches for applied plant breeding and the potential of the traits to assist in the design of the male ideotype for increased cross-fertilization.
