Data dictionary: Dormancy evaluations

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
