| Title : | EVALUATION OF WHEAT GERMPLASM FOR RESISTANCE TO RUSTS |
| Abstract : | Wheat is the most important food grain in Georgia. Rusts are major threat to wheat production all over the world including Georgia. Wheat sown area (46.5kg/ha) and yield (2.1t/ha) are much lower than in other countries. Unfortunately, wheat produced in Georgia meets only 10-15% of local demand. To improve the wheat productivity, CIMMYT in the frame of the International Winter Wheat Improvement Program distributes different international nurseries globally. Since 2000, this network has been providing the Georgian national breeding program with numerous nurseries comprising high yielding advanced breeding lines. As a result of regional testing of these nurseries, seven varieties with broad adaptation to range location have been released in Georgia. The objective of this study was to evaluate the sources of resistance to all three rusts in 85 wheat entries of IN-20RUST-SET under natural and artificial infections. Testing of IN-20RUST-SET germplasm obtained from CIMMYT was conducted at the research field of Institute of P&B during 2020-2021. The results of greenhouse assessment of wheat entries at the seedling stage under artificial infection revealed that 21entries were resistant, 30 and 27 entries were moderately resistant, 26 and 20 - moderately susceptible and five entries- susceptible to leaf rust and stem rust, respectively. The results of field assessment under natural infection of rusts showed that the majority of the genotypes were moderately resistant to leaf rust and stem rust. Natural infection of stripe rust was very low in the research years. Assessment of genotypes with resistant reaction will be continued under heavy infection of rusts. |
