Traits observed

Primary race of the accession.

This indicates the varietal purity of the primary race based on characterization data. It reflects the degree to which the primary landrace exhibits its defining characteristics without significant influence from other landraces.

Secondary race observed in minor frecuency than primry race at the same accession

Describes kernel texture, which is largely dependent on then ratio of hard (horny) endosperm to soft (floury) endosperm.

Describes the secondary predominant kernel texture.

Describes theless frequently observed kernel texture.

The primary external color appearance, the most frequently observed.

The secondary external color appearance, observed less frequently than primary.

The tertiary external color appearance, observed less frequently than secondary.

The quaternary external color appearance, observed less frequently than tertiary.

The quinary external color appearance, the second least frequently observed.

The senary external color appearance, the least frequently observed.

Maturity is determined by considering the flowering dates of all plots.

The first and last flowering dates of the planted cycle are taken to determine the three types of maturity. Example: First flowering date = 40 days, last flowering date = 100 days. 40-60 days = early, 61-80 days = intermediate, 81-100 days = late.

Leaf show the main disease observed in the whole population.

Is rated from 1 to 5 where 1 is no disease and 5 is very severe infection.

Leaf show the second disease observed in the whole population.

The trait is coded 1-5 with 1 representing the lowest damage (< 20% from population) and 5 highest damage (> 80%).

Leaf show the third disease observed in the whole population.

The trait is coded 1-5 with 1 representing the lowest damage (< 20% from population) and 5 highest damage (> 80%).

Shape of the uppermost ears

The primary ear sheath color appearance, the most frequently observed.

The primary ear sheath color appearance, the second frequently observed.

The primary ear sheath color appearance, the low frequently observed.

Number of days from planting to when 50% of observed plants have shed pollen.

Number of days from planting to when silks of 50% of observed plants have emerged

Height of the plant from ground level to the top of the tassel at full growth measured in centimeters (cm)

Altura de la mazorca superior en el tallo central desde el nivel del suelo hasta el nudo donde la mazorca se une al tallo.

It is coded from 1 to 5, taking into account the number of nodes that are visible with roots in the observed plants, where 1 is abundant and 5 is scarce.

Visual rating of plant vigor. Rating is based on plant height, breadth, biomass accumulation, and color.

Classification of the amount of tassel branching from no branching to beyond tertiary tassel branching.

The foliage scale is determined by the amount of light filtered into the soil, and is coded from 1-5 where 1 is abundant and 5 is very scarce.

This data is determined by the presence or absence of pubescence (hair) that appears on the stems of the plants and is measured by Small, Medium and Large.

The ease with which the grain of the cob can be shelled is measured, using a scale of 1 to 5, where 1=Very easy, 2=Easy, 3=Average, 4=Tedious and 5=Difficult.

The size of the glume is measured on a scale of 1 to 5, where 1 = Very large, Large, 3 = Regular, 4 = Small and 5 = Very small.

This data uses a rating scale from 1 to 5 where 1=Excellent and 5=Very poor.

The colour that appears most frequently in plants observed in the first three nodes of the plant from bottom to top. The colours to be taken are: (green/diluted sunred/sunred/purple/dark purple), of which one to three colours can be taken per plot.

The second colour frequently observed in plants observed in the first three nodes of the plant from bottom to top. The colours to be taken are: (green/diluted sunred/sunred/purple/dark purple), of which one to three colours can be taken per plot.

The third colour frequently observed in plants observed in the first three nodes of the plant from bottom to top. The colours to be taken are: (green/diluted sunred/sunred/purple/dark purple), of which one to three colours can be taken per plot.

Number of kernel rows counted on the central part of the uppermost ear on the plant.

Arrangement of kernel rows from the base to the tip of the ear

It is defined according to the timing of flowering (female and male), yield and rotting of cobs (number of selected cobs and number of rotten cobs), appearance of the cobs (if there is homogeneity or if they are uneven). The scale to take these criteria is from 1 to 5, where: 1=Excellent and 5=Very poor.

The colour that appears most frequently in the observed cobs.

The second colour that appears most frequently in the observed cobs.

The third colour that appears most frequently in the observed cobs.

The leaf count is done from the top of the highest ear up to the flag leaf.

The width of the grain is measured in cm.

Diameter of the ear in centimeters measured at the central part of the ear.

The length of the grain is measured in cm.

Length of the ear in centimeters
