THE BEHAVIOR OF SOME MAIZE HYBRIDS CREATED AT ARDS TURDA IN TWO ECOLOGICAL CONDITIONS: TURDA AND LOVRIN

Main Article Content

Abstract

Maize is one of the main crop plants worldwide and nationally, so the improvement of this plant and the creation of new superior productive and adaptive hybrids is an activity of particular importance. In order to promote a hybrid to be registered, it must be tested in several ecological conditions, precisely for this reason, the hybrids created at ARDS Turda are also tested in other locations, one of them being the ARDS Lovrin experimental fields. 24 maize hybrids were tested in the two research stations regarding the yield, thousand kernel weight (TKW) and two vegetative traits of agronomic interest, the plant and ear height. Differences were reported between the two locations, but they were statistically insignificant. Based on the data obtained, 4 maize hybrids were noted, that will be further analyzed regarding several traits, so that one or two will be proposed for registration. These hybrids obtained average yields of over 9,000 kg/ha in both locations, being also noted for their high TKW and uniformity of plant and ear height.
