Quantitative descriptors for agromorphological characterization of taro accessions.

DescriptorCodeDescription

Number of leaves per plantNLPPAll leaves were counted from plant emergence to 150 days after planting (DAP)
Plant height (cm)PHtMeasured from collar region to the attachment point between the leaf petiole and the lamina of the tallest leaf by ruler
Petiole length (cm)PLMeasured from base of the petiole to the attachment point of the tallest leaf by ruler
Leaf length (cm)LLMeasured at longest point in two large sized leaves by ruler
Leaf breadth (cm)LBMeasured at widest point in two large sized leaves by ruler
Leaf areaLAICalculated as L × W × 0.75
Number of sucker’s per plantNSPPAll suckers counted
Days to maturity (days)DMCalculated by counting the number of days taken from planting to final harvest of the crop
Yield per plant (kg)YPPWeighed all corm and cormels obtained from each plant by sensitive scale
Corm weight (g)COWWeighed by sensitive balance
Corm length (cm)COLMeasured from the distal end of the corm to the proximal end, where the outer leaf petiole is attached to the corm by calliper
Corm diameter (cm)CODMeasured at the maximum circumference of the corm using calliper
Cormel weight (g)CRWWeighed by sensitive balance
Cormel length (cm)CRLMeasured from the distal end to the proximal end of the cormel by calliper
Cormel diameter (cm)CRDMeasured at the maximum circumference of the cormel by calliper
Total yield (t ha−1)TYYield per plot converted to yield per hectare (t ha−1)
