Evaluation of value for cultivation and use of seven new rapeseed cultivars in order to registration and commercialization based on UPOV instruction

In order to evaluation of value for cultivation and use of seven new spring rapeseed cultivars (Foruzan, Mahtab, Zaman, Moj, Dalgan, Z10B, SAN14) and seven commercial cultivars of Rapeseed (Sari Gol, RGS003, Hayola 420, Hayola 308, Hayola 401, Hayola 50, and Zafar) as a Reference collection were carried out in a randomized complete block design with three replications at the Seed and Plant Certification and Registration Institute-Karaj in 2015-2016. The measured agronomic traits were including, 1000-seed weight, number of silique per plant, number of seeds per silique, oil percent, Maturity date and grain yield were determined according to the UPOV instruction. The results show that, hybrid cultivars such as Hyola 50 and Hyola 401 have the highest yield. Considering the superiority of Mahtab, Zaman and Dalgan cultivars in terms of yield and having crop value compared to other cultivars, these varieties can be introduced as new cultivars for registration and commercialization.
