Genetic analysis of another culture response in wheat genotypes

Abstract

Androgenic responses of 10 F1 wheat hybrids and 13 parental genotypes were studied. It was observed that the studied androgenic traits (androgenic capacity, callus yield, and frequency of green plants) were genotype dependent. On average for all genotypes, 10.6% of the anthers were responsive and 12.2 calluses were produced per 100 anthers. Line 9D-27-262 and the hybrid 9D-27-262/Posavka-2, had the highest frequencies of green plants, 11% and 12% respectively. It was found that 30.4% of the genotypes produced 2 or more green plants per 100 anthers, which can be considered as sufficient number for use in breeding. Heterotic effects as well as additive and dominant gene actions were found to control the inheritance of all characters. .

U radu je ispitana androgena sposobnost kod 10 F1 hibrida pšenice (Triticum aestivum L.), kao i 13 roditeljskih genotipova. Utvrđeno je da su ispitivana androgena svojstva (androgeni kapacitet, prinos kalusa i frekvencija zelenih biljaka) u velikoj meri zavisila od genotipa. U proseku za sve ispitivane kombinacije ukrštanja androgeni kapacitet je iznosio 10.6%, sa prosečno formirana 12.2 kalusa na 100 izolovanih antera. Linija 9D-27-262, kao i hibrid koji uključuje ovu liniju (9D-27-262/Posavka-2) imali su najviše frekvencije zelenih biljaka (11% i 12%). Rezultati su pokazali da je kod 30.4% genotipova dobijeno 2 ili više zelenih biljaka na 100 izolovanih antera, što se smatra dovoljnim brojem za korišćenje u oplemenjivanju. Heterotični efekat, kao i aditivno i dominantno delovanje gena utvrđeno je u kontroli ispitivanih androgenih svojstava. . PR Projekat Ministarstva nauke Republike Srbije, br. BTR 20138.
