Comparison of Yield of Foreign Maize Hybrids with Local Cultivars

Authors

Abstract

Twenty foreign maize hybrids along with the Irania commercial cultivar (KSC704) and a promising hybrid (KSC 705), as check cultivars, were evaluated in eight locations of Iran (Karaj, Shiraz, Gharakhil, Moghan, Miandoab, Dezful, Isfahan and Ilam) during two consecutive years (2011-12) using randomized complete block design with four replications. Based on the results, hybrid No. 20 (89 May 70) with 11.392 tha-1 produced the highest grain yield followed by hybrids No. 16 (DKC 6589) and No. 15 (DKS 6315) with 11.243 and 11.077 tha-1, respectively, which were not sigficantly different. Based on superiority measure (Pi), hybrids No. 16, 20 and 15 were identified as superior hybrids, respectively. Some inconsistencies were found among stability indices in detection of stable and unstable hybrids. Superiority measure (Pi) almost detected high yielding hybrids as superior.
