Yorkshire Liquorice sweet was first created by George Dunhill from Pontefract, who in the 1760s thought to mix the liquorice plant with sugar. Yorkshire and in particular the city of York played a prominent role in the confectionery industry, with chocolate factories owned by companies such as Rowntree's, Terry's and Thorntons inventing many of Britain's most popular sweets. Another traditional Yorkshire food is pikelets, which are similar to crumpets but much thinner. The Rhubarb Triangle is a location within Yorkshire which supplies most of the rhubarb to locals. In recent years curries have become popular in the county, largely due to
Selection methods in plant breeding based on mode of reproduction species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives a blend of pollen from a large number of individuals each having different genotypes. Such populations are characterized by a high degree of heterozygosity with tremendous free and potential genetic variation, which is maintained in a steady state by free gene flow among individuals within the populations. In the development of hybrid varieties, the aim is
