Correlation between quantitative traits and grain productivity of the waxy maize hybrids

A subspecies of waxy maize (Zea mays L. ceratina) is characterized by the fact that its grain contains 100 % amylopectin starch, a valuable raw material for confectionery production, manufacture polymers, and blood substitute. The absence domestic hybrids in State List Breeding Achievements necessitates study this area breeding. purpose current was to identify dependencies make it possible increase efficiency breeding process when developing hybrids. carried out at FSBSI “ARC “Donskoy” 2020–2022. objects were 36 developed method interline hybridization. studied traits differed degree variation. High coefficients variation identified ‘grain productivity’ (V = 30.1 %) ‘one cob weight’ 21.5 %). ‘number rows’ 8.4 yield during threshing’ 8.2 turned be slightly varying. An values any trait resulted an yield. However, signs productivity not equivalent according their effect on formation There have been most influential productivity, such as cobs per 1 plant’, seeds cob’. correlation between them positive, close (r 0.73±0.12 – 0.82±0.10). positively associated with rest 0.30±0.16 0.74±0.12), selection samples high does reduce other traits. must taken into account selecting initial
