بررسی نقش اندازه بذر بر پارامترهای جوانه‌زنی هیبریدهای حاصل از پایه‌های مادری متفاوت چغندرقند

Seed size is a major factor that affects on uniform emergence of crops. Several studies have shown that the seed size of crop affects on crop yield and some their morphological traits .To investigate the role of sugar beet seed size as a important factor in the breeding process, an experiment was conducted in 2010 in the laboratory under controlled conditions. Treatments were the factorial combination of two factors consists of sugar beet genotypes and seed size. Our results showed that seed germination percentage and mean germination time of genotypes and seeds with a difference size were differed significantly. The results showed qualitative characteristics of seeds that were produced in stages of sugar beet breeding were varied significantly. So, we can use seed size character as a selection factor.
