comment: APPENDIX I. Use of control varieties and data adjustment (for Section 4)\n\nSection 4\n\n1. Adjustment to Control\n\nAdjustment to control values is considered necessary for the majority of descriptors as quantitative data and eye estimates cannot be compared directly when obtained from different environments and/or different years.\n\nFor those descriptors marked "+" in the list, a control with high expression of that character will be nominated. Agreement on particular controls is desirable although it is accepted that different controls will be required in widely different environments.\n\nPopulation means, either eye estimates or metric measurements are expressed as percentages relative to the nominated control (= 100). A 1-9 coding (1 = very low to 9 = very high) is then assigned to the adjusted values, viz:\n\nCode	% relative to control (= 100)\n1	0 - 15.5\n2	15.6 - 31.0\n3	31.1 - 46.5\n4	46.6 - 62.0\n5	62.1 - 77.5\n6	77.6 - 93.0\n7	93.1 - 108.5\n8	108.6 - 124.0\n9	> 124.0 \n\n2. Example varieties\n\nFor those descriptors marked "*" the use of example or delineating varieties is suggested.\n\n4.2.2.1 Time of 50% inflorescence emergence\n\nRaw data will be obtained as number of days after 1 January (= 1) when 50% of the plants have emerged.\n\nCategorization into a 1-9 scale (maturity groups) can either be done using example varieties (UPOv1) or delineating varieties (NIAB2). Characterization in a particular country would follow the system adopted by the registration authority of that country.\n\n1International Union for the Protection of New Varieties of Plants\n2National Institute of Agricultural Botany, UK\n\n4.1.3 Leaf width (non-reproductive)\n\nThe use of example varieties are suggested as an aid to categorization for this character.\n\n3. Evaluation environment and type of planting\n\nThese descriptors are intended to be specific for descriptors in 4 CHARACTERIZATION AND PRELIMINARY EVALUATION and 6 FURTHER CHARACTERIZATION AND EVALUATION, the majority of which are likely to be spaced single plants in the field (4) and field swards (6), respectively. However it is possible in (4) and likely in (6) that data for some descriptors will be obtained from a different type of environment/planting. For example 6.1.14 is likely to be obtained in a glasshouse environment and 6.2.1-6.2.5 from spaced single plants. Any such change must be recorded and related to the descriptor.\n\n4. Name or designation of control variety\n\nWhen a control variety is used to obtain relative data the name of the control will be entered in 3.10 and 5.10. In the event of a change of control for any descriptor this must be recorded and related to the descriptor.\n\n\nAPPENDIX II. Use of control varieties and data adjustment (for Section 6)\n\nSection 6\n\n1. Adjustment to control\n\n6.1.1-6.1.12, 6.1.14 Productivity\n\nProductivity would normally be evaluated in swards by sequential cutting and weighing, exceptionally by eye estimation.\n\nData would be reported as percentages relative to the appropriate maturity-group control for the country of evaluation.\n\nSeasonal yields\n\nThe duration of each seasonal period will need to be defined for each country. As an example the system in use in the UK is as follows - all dates are approximate.\n\nEarly spring:	Growth up to 10 April after a clearing cut at the end of February\n	\nSpring:	Growth up to 1 May\n	\nEarly summer:	Growth between 1 May and 1 July\n	\nLate summer:	Growth between 1 July and 1 September\n	\nAutumn:	Growth between 1 September and 1 November\n\nConservation/Aftermath yields\n\nConservation yield:	Approximately 1-2 weeks after inflorescence emergence\n	\nFirst regrowth:	6 weeks after conservation cut (4 weeks for Lolium multiflorum and Dactylis glomerata)\n	\nSecond regrowth:	6 weeks after first regrowth cut (4 weeks for L. multiflorum and D. glomerata)\n	\nSubsequent regrowth:	The sum of all subsequent cuts taken in September and October\n\n2. Example varieties\n\n6.2.3-6.2.5 Leaf width, leaf length and length of longest culm\n\nExample varieties are suggested as an aid to categorization. UPOV list example varieties for certain characters in Lolium perenne, L. multiflorum. There will be a need for identification of example varieties for other species.\n\n3. 6.2.6 Seasonal inflorescence production\n\nIt is suggested that the following categorization is used as a guide to classification on the 1-9 scale\n\n1 occasional inflorescences\n3 10-50 inflorescences/m2\n5 51-100 inflorescences/m2\n7 101-200 inflorescences/m2\n9 >200 inflorescences/m2\n\n4. Stress, pest and disease susceptibility and alloenzymes\n\nDescriptors in these categories might not be evaluated under the conditions or use the same controls as recorded in 5 SITE DATA for further evaluation. In this event any change must be recorded and related to the descriptor.
