7.Explanations on the Table of Characteristics8.1 Explanation covering several characteristicsCharacteristics containing the following key in the second column of the Table of Characteristics should be examined as indicated below: ( 1 = Absent 1= absent a) To be observed on fresh fully opened flowers (b) To be observed for long and medium type varieties with brown seed color only. The observation is not useful for short type varieties and for varieties with yellow seed color. Varieties are classified in short type varieties (Note 1-4), medium type varieties (Note 5) and long type varieties (Note 6-9) based on characteristic 20 (Stem: length from cotyledon scar to first branch). (c) Should be observed on the top boll (d) Should be observed on single seed taken from top boll. Seeds should be extracted by hand. Seed width and seed length are measured on the same sample of 20 seeds. 8.2 Explanations for individual characteristicsAd. 1: Petal: color of crown at bud stage  
color of crown at bud stage Ad. 2: Time of beginning of flowering Time of flowering is reached when the first flower is open in 10% of plants. Ad. 3: Corolla: arrangement of petals
Ad. 5: Flower: size of corolla  
 The size is the diameter of the corolla observed in the natural position (not with corolla held flat).
Ad. 6: Excluding varieties with corolla color: white: Flower: shape of corolla heart
Ad. 7: Petal: length A   d. 8: Petal: width
Ad. 14: Plant: height Should be measured on the plot including lateral branches (at time of flowering) (see Ad. 21). Ad. 16: Boll: ciliation of false septa  
ciliation of false septa
Ad. 17: Boll: length Ad. 18: Boll: width  
Boll length
Boll width  
Ad. 20: Stem: length from cotyledon scar to first branch Ad. 21: Stem: length from cotyledon scar to top boll C  haracteristics should be observed on the main stem.
