The present research tested, in comparative crops, 15 corn hybrids (F8021 to F8025), created within NIARD Fundulea. The field experiments were conducted under the conditions of ARDS Lovrin during the agricultural year 2023-2024. The comparative corn crop was grown in an unfertilized and unirrigated system, to test the genetic potential of the hybrids. The yield recorded values Y = 3387.80±174.57 kg ha-1 (hybrid F8035) and Y = 5994.47±174.57 kg ha-1(hybrid F8021). Compared to the mean calculated at the experiment level (Y_m = 4804.61±174.57 kg ha-1), nine hybrids recorded yield above the mean value, with statistical safety the hybrids F8021 and F8023 at the p<0.001 level (***), hybrid F8030 at the p<0.05 level (**) and hybrid F8025 at the p<0.05 level (*).Yield values below the experimental mean were recorded for hybrids F8031 and F8035 at the p<0.001 level (ooo), and for hybrid F8027 at the p<0.01 level (oo). In the case of the other hybrids, the differences did not present statistical certainty. The positive yield increase (∆Y) was between ∆Y = 125.71 kg ha-1 (hybrid F8033) and ∆Y = 1189.86 kg ha-1 (hybrid F8021).
