Abstract only

Development of high-yielding winter wheat varieties for various soil-climatic regions of the republic is the primary objective of the grain crop breeding program. In2001-2003, winter bread and durum wheat germplasm obtained from local collections and international nurseries was studied at Absheron Experimental and Production Station. The study objective was to screen the germplasm and identify winter bread and durum wheat lines that are resistant to main diseases and pests and possess desirable agronomic traits that can be employed in breeding. Under the Absheron conditions, main wheat diseases are powdery mildew (PM), yellow rust (YR), leaf rust (LR), common bunt (CB) and loose smut (LS). Up to 400 entries of winter bred and durum wheat were evaluated for resistance to PM, YR, LR, CB and LS under the field conditions. Among the wheat pests the most spread are sawfly, aphid, cereal fly, cereal stem flea, cereal leaf beetle, etc. During the years of the field observations, when high epidemics of wheat rusts was observed, field resistance to YR and LR was demonstrated by 28% and 14% bread wheat entries, and, 11 % and 8% durum wheat entries, respectively. The majority ofthe bread wheat (80%) and durum wheat (50%) entries were affected by PM to a lesser extent (1-2points). Among the local bread wheat entries, high resistance to the most diseases was demonstrated by Parzivan 2, Sheki 1, Azamatli 95, andNurlu 99. Arnong the introduced lines, high disease resistance was observed for four Turkish (GLLF/BEZ // SU 92/ ..., SB-360-5 SB-360,N 92 L208, USA-NE., TIB.80/ ...1332/CUHE), one Russian (Lutescens 468 L 15), one Spanish (Maestro), one Iranian (6406 -Graecum), and two CIMMYT Imes (IK +FN2 and MK+FN3). Complex resistance was observed for Garakilchig 2, Vugar, Baraketli 95, Turan, Terter, Shiraslan 23 and Garabag varieties of local germplasm.
