بررسی خصوصیات زراعی وعملکرد دانه ژنوتیپ های گندم نان در آزمایشات مشاهده ای و مقایسه عملکرد بین المللی در مناطق سردسیر دیم

Introduction is one of the breeding methods. In order to study on agronomic traits and grain yield of bread wheat genotypes recived from CIMMYT/ICARDA center, this study carried out with four observation experimems and one advanced yield trial (totally with 480 genotypes) in seven agricultural research stations of cold dryland (Maragheh, Sararood, Uromiyeh, Ghamloo, Shirvan and Ilam). Agronomic characteristics of genotypes such as: reaction to cold and diseases, date heading, date maturity, plant height. thousend kernel weight and grain yield per hectar compared ,with cbeck varieties (Sadar and Azar 2). Results showed that in 12th facultative and winter wheat observation nursery among 200 different lines and varieties, in Maragheh and Sararood stations 31 genotypes and in Shirvan and Ghamloo stations 38 and 36 genotypes, respectivly and in Ilam station 42 top genotypes were existed compare the checks. In 6th Winter wheat observation nursery for irrigated areas, in Maragheh and Sararood respectively 10 and 14 top genotypes existed among 50 studied genotypes, In 6th winter wheat observatiOn unrsery for semi-arid areas in Maragheh 21 genotypes, in Shirvan 26 genotypes. in Ghidar 16 genotypes, in Uromiyeh 2 genotypes and in Ghamloo 7 top genotypes existed compare the checks. Among 25 varilies and lines in 7th elite yield trial there wasn't any top varitey or line compare the check (Azar 2). Result of study on 130 different genotypes that recived from Kazakestan showed that there were 5 suitable genotypes compare the check, The selected varities and lines from these nurseries will be entered in perliminary yield trial in next year and will compare with checks (Azar2 and Sardari).
