ارزیابی تنوع ژنتیکی لاین‌های اینبرد نوترکیب گندم نان حاصل از تلاقی ارقام زاگرس و نورستار

Production of superior varieties that have helped to increase wheat production, without identification of their genetic variability not be possible. Plant breeders success in the future depends on the preservation of genetic resources at the present time. So the chances of their success depends on the choice of suitable materials and be variability.To study genetic variability of wheat recombinant inbreed lines (RILs), 38 RILs derived from across between Zagros (facultative type, early maturing and drought resistant) and Norstar (winter type, late maturing and cold resistant) along with parental lines were evaluated in randomized complete block design (RCBD) with three replications. Analysis of variance revealed significant differences for lines with respect to yield and yield component. The significant difference between the lines and the high levels of phenotypic coefficient of variation and genetic improvement for grain yield, high genetic variability among the studied lines in this character demonstrated. The highest heritability was observed for number of grain per spike and number of spike per square meter.
