Screening of wheat cross material and breeding lines in respect of susceptibility for bunt duseases on freshly infested and ecologically farmed fields
Project
Project code: 2812OE023
Contract period: 01.03.2013
- 29.02.2016
Budget: 16,700 Euro
Purpose of research: Applied research
Cross material and breeding lines from H. Buerstmayer, BOKU Tulln will be cultivated on fields freshly infested by bunt spores. From heading on infestation with bunt diseases will be evaluated. Trials are harvested and threshed by hand. Purpose of the field trials is to select wheat lines showing resistance or at least a very low infestation disposition towards bunt diseases.
An ecologically farmed field highly infested with bunt spores in recent years is looked for. On this field wheat lines and cross material will be cultivated. Cultivation will be done randomized in rows with 4 replications. Stands will be cultivated and after heading infestation with bunt diseases is evaluated. The total number of plants in one row is determined and the number of infested plants will be counted separately. Rows will be harvested by hand, sacked and stored after drying. Infested plants will be taken out and the remaining plants are threshed. Seed is mixed with bunt balls of the infested plants. The number of bunt spores per kernel of the infested seed is determined according to ISTA working sheet No 53.
Resistant and/or low susceptible wheat lines will be selected and used in further breeding processes, so that in future wheat varieties showing low susceptibility for bunt diseases are available in ecological farming.
