Examination of Genetic Potential for Brain and Possibilities for Introduction in Manufacturing of Genotype Hybrids Maize made in Institute for Cereal Cultures - Thessaloniki, Greece in Pelagonija, the Vicinity of Bitola, R.Macedonia

Abstract

The genetic potential for brain and possibilities for breeding on 14 genotypеs hybrid maize made in Institute for cereal cultures-Thessaloniki, Greece, have been studied. Genotypes hybrid maize belong to the maturity groups of FAO 500 (ΟΜΑΣΑ Α5/35 x B-304, ΟΜΑΣΑ B7/50 x ZPL-51R, ΟΜΑΣΑ Α7/63 x B-304, ΟΜΑΣΑ Α1/101 x B-296, ΟΜΑΣΑ B/287 x M017, ΟΜΑΣΑ Α7/63 x B287, ΟΜΑΣΑ Α4/67 x G-236, ΟΜΑΣΑ Α5/119 x ZPL-51R) and FAO 600 (ΟΜΑΣΑ Α5/90 x ZPL-51R, ΟΜΑΣΑ L4 x ZPL-51R, ΟΜΑΣΑ Α7/63 x G-304, ΑΠΗΣ, ΔΙΑΣ и CONSTANZA), breeding in conditions with irrigation, have achieved quite good genetic potential for brain and can be bred with success in Pelagonia, the vicinity of Bitola. The trait vegetation length from sprouting to technological maturityof genotype hybrid corn from FAO 500 maturity group has yielded averagevegetation length from 123-125 days, but the genotypes hybrid corn fromFAO 600 maturity group has yielded average vegetation length from 128-135days. Each of the studied genotypes hybrid corn display the characteristics inaccordance with their own FAO maturity group.All the studied genotype hybrid corn have yielded quite good brain,the genetic potential for brain was most evident in the genotype hybrid cornfrom FAO 600 maturity group, АпнΣ with average brain from 11 997 kg/ha,average grain moisture from 26, 2 %, and the lower genetic potential for brainwas evident in genotypes hybrid corn from FAO 500 maturity group, ОмаΣаΑ1/101 x B-296 – 6 604 kg/ha, with average grain moisture from 23, 0%.Highest genetic potential for brain from FAO group 500 had the genotypehybrid corn(ОмаΣа Α5/119 x ZPL-51R – 11 497 kg/ha with average grainmoisture from 32,3 %, than ОмаΣа B/287 x M017 - 11 448 kg/ha with averagemoisture from 25,5 %, ОмаΣа B7/50 x ZPL-51R - 11 211 kg/ha with averagemoisture from 21,4 % and ОмаΣа Α7/63 x B-304 - 10 983kg/ha with averagemoisture from 24,2 %).Genotype hybrid corn had the highest genetic potential for brain fromFAO group 600 (АпнΣ –11 997 kg/ha with average grain moisture 26, 2 %,than ОмаΣа Α5/119 x ZPL-51R - 11 497 kg/ha with average moisture from25,4 %, ОмаΣа L4 x ZPL-51R - 11 082 kg/ha with average moisture from 23,4% and КонстанΣа - 10 090 kg/ha with average moisture from 23,0 %).
