genomes, little effort was expended in preserving specific strains or in producing new, high quality cultivars. On top of this, crop yield was highly variable from year to year, due to the effects of disease, pests, and rainfall. Farmers would experience a full crop yield perhaps once in a decade, leading to overplanting, which in turn caused large variances in the supply and price of hops between good and bad harvests. Wye
College started a hop cultivation program in 1904 to address this issue by applying new principles of plant breeding to the crop. By 1917, Salmon and Wye had partnered with the

around the preservative value of the hops, the source of that value, and methods of measurement. Despite this value, brewers generally regarded
American-grown hops as inferior, because of their higher levels of bitterness and particularly because of aromas considered unpleasant at the time. Salmon noted early on that English brewers were forced to blend in American-grown hops for their higher preservative value, despite this inferiority, and his breeding research expanded to include this criterion.

It can take a decade or more to bring a single variety from first breeding to full scale farming and some of Salmon's hops took far longer than this to see commercial use. Brewer's Gold was first planted in 1919, but not released until 1934, nearly two decades later. Cross OZ97a was first bred in

Salmon's first goal for the hop breeding programme, as an extension of his research in plant pathology, was to develop disease-resistant strains. Through Salmon's career, hops were known to be a bittering agent, but research and interest in hops, particularly those originating in the
Americas, was

Until about 1900, there were no large scale, scientific attempts to cultivate new varieties of hops. There were some known varieties, but they were identified primarily by geography and gross differences in the plants' characteristics. While hops were propagated by root cuttings, "cloning" certain

Because of the hit-or-miss nature of finding valuable new varieties, Salmon's procedure was to cross hundreds or thousands of plants each year. By 1930, he said he had grown more than 10,000 seedlings. Some crosses, particularly early in the program, were by open pollination. Later, to select for
