Influența caracteristicilor ameliorative ale liniilor consangvinizate asupra hibrizilor de porumb
2023
Bucor, Nicolae
Inbreeding was studied in maize hybrids of different germplasm groups (BSSS, Iondent, Lacaune, Lancaster) and maturity groups as parental forms, carried out under pedoclimatic conditions of 2022, in the Institute of Phytotechnics "Porumbeni". The crosses studied or realized according to the type of TOPCROSS. As a result, hybrids were obtained from 6 maturity groups, which differed in morphological characters, productivity and the rate of grain water drop at harvest. It was determined that the hybrid groups differed in morphological parameters (plant height, plant height, plant shoot length, panicle length and number of panicle branches), which were more emphasized in the middle maturity group. Including hybrids of the given group are characterized with increased productivity elements and the yield, compared to the other groups is more increased by 1.02-1.87 times. The rate of grain water loss in medium maturity group hybrids is more emphasized in comparison with early hybrids and at the same level with late hybrids.
