Because of the complexity of problems in developing commercially useful hybrid wheat and hybrid barley, breeders are still working intensively along this line. Several obstacles have to be overcome, especially for barley, before hybrids can compete with traditional varieties on the commercial market. In comparison with corn, a 100% cross-pollinator, sorghum has about 15% cross-pollination, while common varieties of barley are almost 100% self-pollinated. Breeding for a high level of cross-pollination is therefore a major task in the development of hybrid barley. Studying hybrid vigour in barley has been hampered by difficulties in producing adequate hybrid seed, and most hybrid performance studies have been conducted at seeding rates much lower than those used commercially, puttinginto question promising results achieved which have showed increased grain yield. This study aims to gain more information about hybrid performance at farm production seeding rates, to collect information on natural cross-pollination and to see how it could be influenced by seeding rate and soil-fertility level, and to learn more about the floral characteristics of a wide spectrum of barley cultivars. The studies were conducted at the Experimental Station, Højbakkegård, near Copenhagen.
