Participatory variety selection is carried out with the direct participation of farmers to select based on their preferences. This method is very important for increasing the adoption and development of new rice varieties with superior characteristics to local varieties. The main objectives of rice breeding program in Iran are to improve new high yielding rice varieties with desirable grain quality, more stability and acceptable to farmers.Therefore, new rice cultivar such as Toka, Tarom Mazand, Gilar, Gilane, Tolo, Omid, Keshvari, Anam and drought-tolerant cultivars Kian and Hasti and promising line 4033 from along with parent cultivar including Hashemi, Tarom Mahali and Fajr were planted in fields of progressive farmers in three sites of the Gilan, Mazandaran, Golestan provinces. Evaluation of the important agronomy characters for Toka, Hasti, Guilar and Line 4033 in the fourteen cities of guilan province showed that the Guilar and line 4033 cultivars had high grain yield (6.5 and 6.4 t/ha) in Langrud and Rudsar county. The results showed that the grain yield of Guilar cultivar (5.5±251.8 t/ha), Hasti (4.7±202.3 t/ha), Toka (4.6±142.9 t/ha) and Line 4033 (5±195.9 t/ha) was higher than Hashemi (4.135 ± 1.3 t/ha) in all of the sites in Giulan province. In addition range of panicle number per plant was 14-30, higher than Hashemi with 12-13 panicles in all of sites. All of the rice farmers in the studied sites had consensus the early maturity and higher yeild of new cultivars and line compare to Hashemi cultivar and they know this trait along with resistance to lodging are one of outstanding characteristics in this line. Results of the important agronomy characters evaluation for Shiroodi, Helal, Anam, Hashemi, Binam and Tarom Mazand cultivars in the three cities of Mahmoudabad, Amol and Babolsar in Mazandaran Province showed that Hellal had an average yield of 9.4 t/ha which was higher than Shiroodi with a yield of 8.1 t/ha. Also, the average of grain yield of Tarom Mazand and Anam cultivars in the studied sites were 5.2 and 5.5 t/ha, respectively, which were higher than that of Binam and Hashemi (about 4). All farmers consensus that the Hellal and Anam dwarf cultivars and the Tarom Mazand cultivar in addition to their early maturity, have a desirable cooking quality. Results of the important agronomy characters evaluation for Fajr, Tolo, Omid, Keshvari, Anam, Gilaneh, Kian and Toka cultivars in mechanized cultivation (Direct Seeding) in the three cities of Ramian, Agh ghala and Gorgan in Golestan Province showed that the Fajr and Omid cultivars (certified Seed) had high grain yield (7.9 and 7.7 t/ha) compared to the Fajr cultivar (control) with a yield of 5.4 t/ha , Meanwhile these genotypes had the lowest grain yield in Gorgan city. The data results showed that in the studied cities, the grain yield cultivars, Tolo (5.05 ± 819.1 t/ha), Keshvari (4.4± 272.7 t/ha), Omid (4.2± 224.6 t/ha), and Fajr (certified seed) cultivar (3.8± 228.1 t/ha), were higher than the average yield of the check Fajr cultivar. The results also showed that the drought-tolerant Kian cultivar in Ramian and the Gilaneh and Toka cultivars in Gorgan also have a good yield of about 4 t/ha under direct Seeding conditions. In all the studied areas, the plant height of the Tolo, Omid, Anam and Keshvari varieties was 99.1 ± 8.1, 96.7 ± 10.5, 91.7 and 99.6 ± 8.1, respectively less than the Fajr cultivar 107.3 ± 3, which indicates the more resistance of these cultivar to lodging. The results showed that Gilaneh and Tolo cultivars had the shortest growth period with an average growth period of 95 days and 107.7±16.4 days, respectively. Eventually, according to the conditions and system of rice cultivation in Golestan province, the high-yielding Tolo and Keshori cultivars and the high-quality Gilaneh, Toka, and Kian cultivars can be suitable for cultivation more in the direct seeding method than the common cultivars in the area.
