STUDY REGARDING THE QUALITY AND PRODUCTIVITY POTENTIAL OF SOME PERSPECTIVE MAIZE HYBRIDS CREATED AT ARDS LOVRIN

Abstract

Zea mays L. is an important annual crop species, belonging to Poaceae family, a species that comes from teosinte (Zea mays L. spp Mexicana). Maize kernel is an edible and nutritive part of the plant, this crop being an essential source of various phytochemicals, vitamins, minerals and other micro- and macronutrients. Maize breeding is considered to be an important and complex program that has has unique elements, which are different from other cultivated self-pollinated crops, each obtained hybrid having its own combination of genetic effects. Therefore, this paper aims to study a comparative culture with 20 maize hybrids created at ARDS Lovrin, hybrids from indurata and dentata convarieties, in order to highlight hybrids with a high productive or qualitative potential. Regarding to production capacity, the analyzed hybrids had a different behavior, the highest values being recorded at H10-1010 (9767 kg*ha^-1) and H13-1013 (9631 kg*ha^-1) hybrids. The highlighted hybrids differs significantly from the other ones, registering an increase of 32.6%, respectively 30.8% compared to the experience average. In terms of quality, the following hybrids H1, H3 and H19 were evidentiated. H1-1001 hybrid registered a protein content in kernel of 11.30% and oil by 6.55%; H3-1003 hybrid registering close values, of 11.35% protein and 6.65% oil content and H19 hybrid with 10.95% protein content, respectively 6.50% oil content in kernel. Summing up, from the results obtained for the hybrids taken in study, the hybrids mentioned above were highlighted, from both qualitative and productive point of view.
