Sažetak
KWS Borlaug Stipendium is a 6-month study visit for wheat scientist to work at a KWS site in Germany (Wohlde) on research and development related to CIMMYT priorities which include wheat breeding and coincide with the seasonal activities of KWS. This Stipendium is named after American biologist Norman Borlaug, who is responsible for ‘Green Revolution’ and ´The Man Who Saved A Billion Lives´. He was awarded the Nobel Peace Prize in 1970 in recognition of his contributions to world peace through increasing food supply. Regarding to activities of this fellowship we have been working on wheat resistance to biotic stress, such as Fusarium head blight, yellow and stem rust which can be a highly destructive diseases of wheat and are capable of destroying entire wheat fields over a large area within a short time period. Fusarium head blight reduces seed quality and yield, but the most serious problem for human and animal consumption is the capability of the fungus to produce toxic metabolites (mycotoxins), including deoxynivalenol (DON). Heavy rusting causes early loss of leaves, which reduces the grain filling period and results in smaller kernel size. The best approach to control FHB and rust diseases is to create wheat genotypes which are carrying effective resistance genes which can be possible through research with artificial inoculations in the field nurseries where resistant material at high infection can be selected. Second fellowship work includes part of activities in hybrid wheat breeding. Hybrids could provide the way to overcome the yield barriers because heterosis does exist when compatible parental combinations are made. Hybrid production is a promising approach because of: 1) more stable and higher yield (increased 1000 kernel weight ; grain filling rate faster) ; 2) more powerful root system- better use of the nitrogen ; 3) more healthy profile/better stress tolerance ; 4) more tolerance to Fusarium head blight ; 5) higher straw productivity-additional income. KWS-Borlaug Fellowship is supported by KWS LOCHOW GMBH.
