Dr Harold Howard
Dr. Harold Wakefield Howard OBE (25 March 1913 - 1 January 1985) was a botanist, best known for breeding the Maris Piper potato variety, which was the first potato variety to be resistant to potato cyst nematodes. Dr. Howard’s research at the Plant Breeding Institute, Cambridge to develop a variety of potatoes resistant to the potato cyst nematodes was a significant scientific achievement, as this pest caused losses estimated at £30M annually, for this work he was awarded an OBE The Most Excellent Order of the British Empire is a British order of chivalry, rewarding valuable service in a wide range of useful activities. It comprises five classes of awards across both civil and military divisions, the most senior two o ... in 1976. The Maris Piper potato variety is still the most popular potato variety in the UK. Howard also wrote a book on potato genetics "Genetics of the Potato: Solanum Tuberosum" References British agriculturalists British botanists Officers_of_the_ ...

Potato Cyst Nematode
Potato root nematodes or potato cyst nematodes (PCN) are 1-mm long roundworms belonging to the genus ''Globodera'', which comprises around 12 species. They live on the roots of plants of the family Solanaceae, such as potatoes and tomatoes. PCN cause growth retardation and, at very high population densities, damage to the roots and early senescence of plants. The nematode is not indigenous to Europe but originates from the Andes. Fields are free from PCN until an introduction occurs, after which the typical patches, or hotspots, occur on the farmland. These patches can become full field infestations when unchecked. Yield reductions can average up to 60% at high population densities. Biology and life cycle The eggs hatch in the presence of Solanoeclepine A, a substance secreted by the roots of host plants otherwise known as root exudates. The nematodes hatch when they grow into a second-stage juvenile (J2). At this stage, the J2 nematodes find host cells to feed off of. The potat ...

Plant Breeding Institute
The Plant Breeding Institute was an agricultural research organisation in Cambridge in the United Kingdom between 1912 and 1987. Founding The institute was established in 1912 as part of the School of Agriculture at the University of Cambridge. Rowland Biffen was the first director, and was close with William Bateson who was leading studies of heredity in Cambridge following the rediscovery of the pioneering genetic research of Gregor Mendel in 1900. Biffen began studying cereal breeding in the early 1900s with the aim of producing improved varieties for farmers and millers, and also to test whether Mendel's laws applied to wheat. He demonstrated that resistance to yellow rust was a dominant trait and this culminated in 1910 in the release of the rust-resistant variety Little Joss, which was widely grown for decades and used as a parent for many other varieties. The institute's site was to the west of Cambridge, and it shared land with the School of Agriculture that is today th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding valuable service in a wide range of useful activities. It comprises five classes of awards across both civil and military divisions, the most senior two of which make the recipient either a Orders, decorations, and medals of the United Kingdom#Modern honours, knight if male or a dame (title), dame if female. There is also the related British Empire Medal, whose recipients are affiliated with the order, but are not members of it. The order was established on 4 June 1917 by King George V, who created the order to recognise 'such persons, male or female, as may have rendered or shall hereafter render important services to Our Empire'. Equal recognition was to be given for services rendered in the UK and overseas. Today, the majority of recipients are UK citizens, though a number of Commonwealth realms outside the UK continue to make appointments to the order. Honorary awards may be made to cit ...
