Field experiments were
conducted during the 2015 – 2016 growing seasons in Konya, Turkey. Seven inbred
lines, 3 testers and 21 F1 progenies that were produced by line x
tester mating design in 2015 were used as materials. Seeds of each genotype were sown by hand to 5
m long rows according to “Randomized Complete Block Design” with three replications
with spacing of 70 × 20 cm in second week of May in 2016. Each replicate plot
was consisted of two 5 m long rows. Corn cobs of parentages and crosses were
harvested manually in October when the moisture content of the grains was approximately 20%. Laboratory
analyses were performed during the 2017 – 2018 with seeds of 7 inbred lines, 3
testers and 21 hybrid maize combinations. Crude oil content (COC), crude
protein content (CPC), hectolitre weight (HW), starch content (SC) and thousand
grain weight (TGW) traits of each genotype were determined. The variance
compounds of the population, general combining abilities (GCAs) of the
parentages and specific combining abilities (SCAs) of the progenies were
calculated. Line 3.2 (CPC; 0.448*, HW; 8.794*, TGW; 24.805**), line 3.4 (CPC;
0.054*, COC; 1.019**, HW; 23.905**), line 14.21 (CPC; 0.176**, COC; 1.297**,
HW; 18.349**), line 3.6 (COC; 1.441**, SC; 2.145**), line 14.2 (SC; 1.675**,
HW; 21.460**), line 14.26 (SC; 2.566**, TGW; 35.550**) and line 14.20 (CPC;
0.767**) had significant and positive GCAs at several properties. Our results
suggested that this population is suitable for developing progenies with
appropriate quality traits.
