Abstract
The three-year four-replication trials with two sowing densities were set up according to randomized complete block design under conditions of irrigation in two locations in order to determine the effects of a proportion and a size of a vegetation area of parental lines on the number of seeds of maize hybrids ZP 42 A and ZP 704. Hemp was sown in border belts of 3.2 m in width that were the isolation between experimental variants. The number and the arrangement of parental rows were 4:2 in favor of a female component. The number of plants per area unit amounted to 55,000 and 65,000 per hectare. The inter-row distance for the female component amounted to 70 cm, while there were the following two distances for the male component: 70 cm and 50 cm. The proportion of areas under female component plants amounted to 66.7% and 72.2%. A statistically high significance of the environment (location x growing season), the inter-row distance of male component plants, the rows of female component pla...nts and the density, i.e. the number of plants, was determined by the analysis of variance for the total number of kernels-seeds per ear of female component plants.

Tokom trogodišnjih istraživanja u dve lokacije i dve gustine, utvrđen je uticaj proporcije i veličine vegetacionog prostora roditeljskih linija na broj semena hibrida kukuruza ZP 42 A i ZP 704. Ogled je postavljen po potpuno slučajnom blok-sistemu u četiri ponavljanja u uslovima navodnjavanja. Izolacija između oglednih varijanti bila je konoplja zasejana u trake širine 3,2 m. Broj i raspored redova roditeljskih linija bio je 4:2 u korist linije-majke. Broj biljaka po jedinici površine bio je 55.000 i 65.000 biljaka po hektaru. Za redove biljaka linije-majke međuredno rastojanje iznosilo je 70 cm a kod redova biljaka linije-oca bile su dve varijante: 70 cm i 50 cm. Učešće (proporcija) površine pod biljkama linije-majke iznosila je 66,7% i 72,2%. Analizom varijanse za ukupan broj zrna-semena na klipu biljaka linije-majke utvrđena je statistički visoka značajnost spoljne sredine (lokacija x vegetacioni period), međurednog rastojanja biljaka linije-oca, redova biljaka linije-majke i gustin...e tj. broja biljaka.
