Testing the stability of grain yield and bread-making quality of wheat varieties in two different years
25 winter-type bread wheat genotypes were evaluated in two consecutive years (2010 and 2011) in the nursery of Cereal Research Non-Profit Company (CRNPC) to test the stability of grain yield and quality traits of CRNPC-bred varieties. In spite of the earlier trends the extremely wet 2010 year’s grai...

| Tartalmi kivonat: | 25 winter-type bread wheat genotypes were evaluated in two consecutive years (2010 and 2011) in the nursery of Cereal Research Non-Profit Company (CRNPC) to test the stability of grain yield and quality traits of CRNPC-bred varieties. In spite of the earlier trends the extremely wet 2010 year’s grain yield became significantly lower and bread-making quality proved to be poorer than in the dry 2011 year. The most significant reasons of those found to be the very strong disease (mostly leaf rust and Fusarium) infection pressure in the highly precipitated 2010 year. Other, minor reasons were water logging stress, and harvest deficits due to the remarkable lodging of wheat. Stability of grain yield and different quality traits (wet gluten content, gluten stability, kernel hardness, farinograph water absorption, farinograph value, Zeleny-value, falling number) were evaluated by regression calculations to test the varieties’ adaptability to the different year effects. In case of yield, a wide variation was found in stability of grain output. In cases of quality traits, the most sensitive traits were falling number, farinograph water absorption and developing time of dough. |
