Determination of Yield and Yield Components of Some Sweet Corn Genotypes in Diyarbakır Conditions

This research was carried out to determine high yielding sweet corn genotypes suitable for conditions in Diyarbakır. In the research, 10 variety candidate hybrids and 2 commercial varieties standard were used. The research were conducted, the experimental design was a randomized complete block with three replications in 2015 and 2016 years. According to the two-year mean results obtained from the experiment; the tasseling periods 55.8 day (ŞADA 34)-68.2 (ŞADA 14) day, plant height 164.3 cm (ŞADA 34)-210.3 cm (Batem Tatlı), first cob height 40.7cm (ŞADA 31)-69.9 cm (ŞADA 14), ear thickness 36.9 mm (ŞADA 31) -43.6 mm (Merit), ear length 15.7 cm (ŞADA 31)-21.5 cm (ŞADA 12), kernel/cob 79.7% (ŞADA 14)-85.5% (Merit, ŞADA 32), dry grain yield between 290.2 kg da-1 (ŞADA 31)-553.6 kg da-1 (ŞADA 32) and fresh ear yield between 651.4 kg da-1 (ŞADA 34) -1183.8 kg da-1 (ŞADA 33) showed changes. As a result; ŞADA 33, ŞADA 32, Batem Tatlı, ŞADA 16, ŞADA 12 genotypes gave higher values in terms of fresh ear yield and ŞADA 32, Batem Tatlı, ŞADA 12, Merit, ŞADA 33, ŞADA 10 and ŞADA 16 genotypes gave higher values in terms of dry grain yield respectively.
