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.

Traits observed

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

A unique number representing each germplasm.

Visual measurement recorded three weeks after emergence of the seedling.

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

Mean height of 10 random plant ears from the ground level to the node bearing the upper ear.

Number of days from planting to when 50% of the plants have extended silk.

Midrib colour of the third leaf counted from flag leaf downwards taken during or shortly after flowering.

Susceptibility to lodging. Scored before harvesting in a scale similar to percentages.

Average of 10 randomly selected plants from the middle of the plot.

Average number of basal tillers (without counting the stem)at maturity of 10 randomly selected plants.

Mean length of 10 random ears from the point of attachment on the ear peducle to the tip of the dehusked ear.

Number of rows of kernel on 10 randomly selected ears.

Number of ears randomly harvested and characterized in the lab.

Visual measurement whether the kernel colours are the same or not.

Three colours observed in order of frequency.

Weight of one thousand seeds adjusted to 10% moisture content.
