Characteristic Abbreviation Description Units
Number of Sample SAMPLE number
Initial tuber weight ITW The same day or a day before tuber storing gr.
Date of sprouting DATESP date
Dormancy period DORPD Counted as days from haulm_cutting to sprouting of 80% of the tubers with at least one sprout longer than 2 mm. Monitoring of sprout initiation and growth should be carried out at 10 day-intervals in order to record an accurate dormancy period days
Number of Sprouts NSP 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded count
Length of the longest LGLNSP 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded mm.
Length of the lateral sprout number LGLATSP 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded. Measure should be performed in every lateral sprout of a tuber (exclude the longest one). An average is calculated per tuber gr.
Average length of lateral sprout AVLGLATSP mm.
Thickness of apical sprout THASP mm.
Thickness of lateral sprout number THLSP number
Average sprout thickness AVTHSP 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded. Measure should be performed in at most three sprouts per tuber in multiple sprouting tubers(include the longest one) Suggestion: use a Vernier calliper. An average is calculated per tuber number
Final tuber weight FTW 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded. Remember to remove sprouts carefully before weighing number
Percentage weight loss of unsprouted tuber PW_USPT %
Percentage weight loss of sprouted tuber PW_SPT %
Sprouting pattern SPPAT Apical sprout or an average less than 2 sprouts per tuber, an average of less than 3 be considered a partial dominance, or more sprouts per tuber indicates the absence of apical dominance or a pattern of multiple sprouts text
