Determination of agricultural characteristics of some hybrid genotypes obtained from dental corn (zea mays indentata sturt.) lines

Corn is one of the cultural plants that production and consumption is increasing day by day in our country and in the world. Since the amount produced in Turkey does not meet the need in some yerars, corn is imported from abroad. For his reason, corn production needs to be increased in Turkey. This study was made to determine the yield, yield elements and some morphological and phenological characteristics of some F1 single hybrid genotypes obtained from inbred dent corn lines. The trail was carried out in Konya ecological conditions during the 2024 vegetation period. A total of 30 hybrid (F1) dent corn genotypes, including 25 hybrid genotypes and five commercial varieties, were used in the study. The experiment was set up in randomized complete block design with three replications. Sowing was made on 26 April 2024. In the research, tasseling period, plant height, first ear height, number of ear per plant, ear length, ear diameter, number of kernel per ear, 1000-kernel weight, single ear weight and grain yield were investigated. In the study, statistically significant differences were found for all traits examined except the number of ears per plant. While the highest grain yield was obtained from the P0937 standard variety with 1560.0 kg/da, the lowest grain yield was obtained from the 1046 coded genotype with 861.5 kg/da. While the average yield of standard varieties was determined as 1381.5 kg/da, the average yield of genotypes was determined as 1175.9 kg/da. However, some genotypes performed above the average yield of commercial varieties. Genotypes 1075 and 1074, which gave 1498.6 and 1474.6 kg/da grain yield, were higher than the other four commercial varieties except P0937. According to the results obtained, it can be said that the genotypes coded 1075 and 1074 are considered promising for the ecological conditions of Konya. The study should be conducted over several years or in different locations in the same year, to obtain more reliable results and make more accurate recommendations.
