Implication

Genetic analysis reveals improved traits in BC2F2 and BC2F3 sweet corn populations, indicating potential for breeding.

Key Points

  • Superior landrace CAUM66β+ showed high beta carotene and productivity traits, and could benefit future breeding.
  • Heritability estimates ranged from 46.83% to 97.38%, indicating strong genetic influence on several agro-morphological traits.
  • Genetic variability analysis indicated the potential for selection of lines based on traits like cob length and number of kernels per row.
  • Positive skewness in traits like tassel branches suggests a polygenic control, enhancing the selection process in breeding programs.
