Dataset details

Characterization of maize accessions in Muguga (Kenya)

1.0

Maize accessions were planted in Muguga and assessed for their morphological diversity. The results indicate that the maize accessions held at genebank are variable interms of kernel characteristics, plant height and days to maturity.

    Number of days from sowing to 90% of plants reaching physiological maturity.

  • National accession number

    A unique number representing each germplasm.

  • Seedling vigor

    Visual measurement recorded three weeks after emergence of the seedling.

  • Plant height

    Mean height of 10 random plants, measured from the ground level to the tip of the head taken after flowering and before ripening.
