Variability and correlation between properties of maize hybrid seeds of different fractions obtained after seed processing and the initial seedling growth

The shape and the size of maize seeds are most variable traits, which determined by a genotype environmental conditions. aim this study was to understand effects mechanism relationship significance seed variability on germination morphology seedlings. five hybrids ZP388, ZP434, ZP555, ZP606, ZP6263 were used in study. following traits analysed: physical ones: length (L), thickness (T) width (W); morphological weight (SW), seedling (SLW), root (RL), shoot (SL) (G) as phydiological trait. There statistically significant differences not only among (p?0.05), but also (p?0.05). Statisticlly (W), length(L) all small flat fraction (SP). large rounded (KO) mainly differed between ZP434 ZP 555, while these two hybrids. Large-flat (KP) fractions characterized highest (99%). As increases, decreases (R2=0.527). Segmentation within according diversity physiological properties carried out size, weight, other parameters less important. characteristic is that KP have high well-developed
