Borlaug's new semi-dwarf, disease-resistant varieties, called Pitic 62 and Penjamo 62, changed the potential yield of spring wheat dramatically. By 1963, 95% of Mexico's wheat crops used the semi-dwarf varieties developed by Borlaug. That year, the harvest was six times larger than in 1944, the year Borlaug arrived in Mexico.
Wheat is a group of wild and domesticated grasses of the genus Triticum (/ ... By 1997, 81% of the developing world's wheat area was planted to semi-dwarf wheats ...
Norin 10 wheat (小麦農林10号) is a semi-dwarf wheat cultivar with very large ears that was bred by Gonjiro Inazuka at an experimental station in Iwate Prefecture, Japan. Its parents were a semi-dwarf Japanese landrace that may have originated in Korea in the 3rd or 4th century AD, and two varieties from the USA. [1]
Wheat origins by repeated hybridization and polyploidy (e.g. "6N" means 6 sets of chromosomes per cell rather than the usual 2). Only a few of the wheat species involved are shown. The goatgrass species involved are not known for certain. [6] Aegilops is important in wheat evolution because of its
A Japanese dwarf wheat cultivar Norin 10 developed by Japanese agronomist Gonjiro Inazuka, which was sent to Orville Vogel at Washington State University by Cecil Salmon, was instrumental in developing Green Revolution wheat cultivars. In the 1960s, with a food crisis in Asia, the spread of high-yielding variety rice greatly increased.
Common wheat was first domesticated in West Asia during the early Holocene, and spread from there to North Africa, Europe and East Asia in the prehistoric period. [citation needed] Naked wheats (including Triticum aestivum, T. durum, and T. turgidum) were found in Roman burial sites ranging from 100 BCE to 300 CE.
Swaminathan and Norman Borlaug collaborated, with Borlaug touring India and sending supplies for a range of Mexican dwarf varieties of wheat, which were to be bred with Japanese varieties. [45] Initial testing in an experimental plot showed good results. The crop was high-yield, good quality, and disease free. [46]
Wheat dwarf virus (WDV) is a plant pathogenic virus in the family Geminiviridae. The two isolates of WDV affect wheat and barley . It is spread by the leafhopper Psammotettix alienus .
