Palmitic acid glyceride content in maize lines - carriers of the <i>wx</i> and <i>sh1</i> mutations depending on the air temperature during the ripening period

In three-year experiments, we studied the effect of air temperature during grain ripening on content palmitic acid glycerides in oils corn (<i>Zea mays</i> L.) inbred lines common type as well - carriers <i>sh1</i> and <i>wx</i> mutations endosperm structure. The material for research was presented by 10 unrelated each type, which were grown Steppe zone Ukraine. analysis fatty composition oil carried out with Peisker gas-chromatographic method. evaluation genotype: environment interactions using Eberhard-Russell It has been established that – differ from a higher level palmitate content, one probable causes this may be spatial linkage mutant genes palmitate-coding locus chromosome 9. Palmitate varied depending genotype line norm its response to fluctuations maturation. Some showed significant range variability under different regimes period, while other had fairly stable trait same conditions. Lines stably elevated contrasting growing conditions identified.
