Abstract :
In order to investigate the comparing, the yield and some morphological characteristics of forage corn promising genotypes in Tehran province, an experiment in a randomized complete block design with four replications in 2015 was conducted. In this experiment, 17 promising genotype were evaluated. The measured characteristics was included stem diameter, ear height from the ground, ear length, leaf area index, leaves number, fresh and dry forage yield, protein content and protein yield. The variance analysis results showed that there was difference between the promising genotypes at one percent probable in the possibility of leaf area index, dry forage yield, protein content and protein yield and at five percent probable in the possibility of fresh forage yield. In terms of mean comparison, there was difference between promising genotypes at the highest ear height from the ground was not observed. The most leaf area index in genotype 10 (K166b×K18) was obtained. The most number of leaves per genotype 15 (KLM77007/7-3-1-2-2-1-1× K18 (and the most stem diameter in genotype 12 (KLM77007/7-3-1-2-2-1-1× K18 (was obtained. The most fresh forage yield in genotype 11) K47/2-2-1-3-3-1-1-1×K19 (and dry forage yield in genotype 17 (SB73×MO17 (was observed. Also the most protein percent is related to the (K47/2-2-1-3-3-1-1-1×K1 (, 12 (KLM77007/7-3-1-2-2-1-1×K18 (and 14 (K47/2-2-1-2-1-3-1-1×K18 (and the most protein yield is related to the genotypes 11 (K47/2-2-1-3-3-1-1-1×K19( and 17 )SB73×MO17(.
