Many thanks Steve. below is the dode: Proc mixed;      class block variety;      model yield=variety;      random block;      lsmeans variety/pdiff;      ods output Diffs=d; run; This is an augmented design where 200 varieties and 5 checks have been tested in an Augmented randomized complete block design. The 200 varieties have been unreplicated in 20 blocks of 10 plots each. Each block has been completed by the 5 checks. Hence a total of 300 plots (200+5*20). Thanks Gaston ... View more
