Determination of genetic purity of wheat in formal and informal wheat seed production systems by using phenol test via image analysis technique

Beside prevalent methods for determination of genetic purity, image analysis technique can also be used with a high reliability. For evaluation of image analysis application on determination of genetic purity of wheat varieties, a research was carried out at seed and plant certification and registration research institute (SPCRI) in Karaj, Iran, 2011-12. So, BITA-technique (Biochemical and Imaging technique for Analysis) and BITA-image analyzer were used for assessment of genetic purity. Based on the results, there was no significant difference between formal and informal seed production in Tehran province while meaningful difference was observed between two seed production system in Kermanshah and west Azerbaijan provinces in a way that higher seed genetic purity was observed in formal section. Generally, the maximum genetic purity (99%) was observed in both formal and informal wheat seed production systems in Mahidasht and Naghadeh areas of Kermanshah and West Azerbaijan Provinces, while the lowest genetic purity (26%) was related to formal seed production system in Ravansar area of Kermanshah Province. So, for producing seeds with higher genetic purity, the current managements and inspections in seed production systems should be evaluated for identifying the problems and planning for solving them.
