Mode of inheritance for 100 kernel weight and grain yield of maize

Abstract

The aim of this paper was to investigate the genetic variability and the mode of inheritance between inbreed lines and their hybrids, for three very important traits, cob weight, 100 kernel weight and grain yield. Eight inbreed lines are domestic germplasm made at Institute of Field and Vegetable Crops, and three are from USA. Statistical data analysis shows genetic variability between inbred lines for every analyzed trait. Superdomination was mode of inheritance for cob weight and grain yield, found in every observed combination. Obtained results confirmed superdomination and domination, as mode of inheritance for 100 kernel weight. Highly positive correlations were determined between cob weight and 100 kernel weight, cob weigh and grain yield and 100 kernel weight and grain yield. .
