Quantitative Traits | Code | Description |
Sprout count | SPC | Number of primary/mother shoot emerged from planted bud |
Tiller count | TC | Number of secondary, tertiary, etc shoots emerged from primary shoots |
Leaf length (cm) | LL | Length of the third leaf from the flag leaf |
Leaf width (cm) | LW | Width of the third leaf from the flag leaf |
Leaf area (cm2) | LA | Area of the third leaf from the flag leaf, computed as (leaf length × leaf width × 0.747) suggested by Stickler et al. (1961) |
Stalk count 10 month after planting | STC10MAP | The number of millable stalks 10 month after planting |
HRBrix percent 10 month after planting | HRBrix10MAP | Hand rifractometer brix reading 10 month after planting |
Number of millable canes (count)/plot | MSCPL | stalks with four or more visible internodes at 10 months or after |
Number of millable canes (count)/hectare | MSCHA | Number of millable cane produced per hectare calculated from millable stalk count per plot |
Stalk thickness/diameter (cm) | SD | Width of stalk at mid internode |
Stalk height/Cane length/ (cm) | SH | Height of a sugarcane plant measured from ground level to the top visible dewelap. |
Number of internodes (count) | NI | Count of total internodes per plant |
Internode length (cm) | IL | Length of the third internode counted from the ground surface |
Cane yield per plot (Kg) | CYPL | Weight of cane harvested from an experiment plot |
Cane yield per hectare (qt/ha) | CYHA | The weight of millable sugarcane produced per hectare of land or calculated from cane yield per plot |
Single cane weight (kg) | SCW | Weight of cane harvested from an experiment plot divided by the number of millable cane per plot |
Brix percent | Brix% | Juice Brix refers to the total solids content present in the juice expressed in percentage. Brix includes sugars as well as non-sugars as indicated by a brix hydrometer. |
Pol percent/ Juice Sucrose percent | Pol% | The juice sucrose per cent is the actual cane sugar present in the juice determined by reading on the scale of polarimeter. |
Purity percent | Purity% | The ratio of pol to brix. Pty = Pol/ Bx × 100 |
Sugar percent | SR% | Amount of sugar recovered from the cane. Obtained by the formula: = ((pol% − (brix% − pol%) * 0.7)) * 0.75 as described in Winter Carp indirect method of cane juice analysis [11] . |
Sugar yield per hectare (qt/ha) | SY | Amount of crystal sugar produced per hectare of land. Obtained by multiplying cane yield per hectare with sugar percent |
