     obs, 9 var) and  carolina3(64 obs, 5 var).

     Carolina1: Data for the analysis of Carolina I Genetic design. In
     this design F2 or any advanced generation maintained by random
     mating,  produced from cross between two pure-lines, is taken as
     base population. From the population an individual is randomly
     selected and used as a male. A set of 4 randomly selected plans
     are used as females and are mated to the above male. Thus a set of
     4 full-sib families are produced. This is denoted as a male group.
     Similarly, a large number of male groups are produced.  No female
     is used for any second mating. four male groups (16 female groups)
     from a set.

     Carolina2: Data for the analysis of Carolina II Genetic design.
     Both paternal and maternal half-sibs are produced in this design.
     From an F2 population, n1 males and n2 females are randomly
     selected and each male is crossed to each of the females. Thus n1
     x n2 progenies are produced whitch are analysed in a suitably laid
     experiment.

     Carolina3: Data for the analysis of Carolina III genetic design.
     The F2  population is produced by crossing two inbreds, say L1 and
     L2.  The material for estimation of genetic parameters is produced
      by back crossing randomly selected F2 individuals (using as
     males) to each of the inbreds (used as females).
