OBJECTIVE DESCRIPTION OF VARIETY

Ryegrass (Lolium spp.)

NAME OF APPLICANT (S) TEMPORARY OR EXPERIMENTAL DESIGNATION VARIETY NAME

ADDRESS (Street and No. or RD No., City, State, Zip Code and Country) FOR OFFICIAL USE ONLY

PVPO NUMBER

Place the appropriate number that describes the varietal character of this variety in the boxes below. Place a zero in the first box (e.g. 0 / 8 / 9 / or 0 / 9 /) when 

number is either 99 or less or 9 or less. Descriptions of characters should represent those that are typical for the variety. Measured data must be for SPACED

PLANTS. Give additional description for all characteristics that cannot be adequately described in the form below. Append all pertinent comparative trial and 

evaluation data. 

 

Cultural Conditions

All measurements must be on spaced plants with a minimum of (30 cm) between plants. A minimum of 30 plants and 60 data points must be used for all 

measurements. Plants must be established no later than the previous fall for spring and summer measurements. Trials should be irrigated and stem rest control

practiced. Cultural conditions must be stated in comment section and plant number / data points shown in all tables.
