Some of the methods or Allard (1), Kempthorne (3), Mather (4), Powers (5), and Powers et al. (6) were coded using the FORTRAN language for reduction and manipulation of individual plant data from the three nonsegregating generations (P1( P2, Fj.) and the three segregating generations (F2, BQ, BC2). After deriving phenotypic variances, genetic variances, heritability, minimum factor number, and scale tests, an attempt is made to fit the data to a 1-locus hypothesis with indicated dominance, and to various 2-loci hypotheses with varying linkage, relative gene value, dominance, and parental genotypes. Program limitations are: (a) 6 characters or less simultaneously, (b) 24 replications or less, and (c) number of plants per replication is limited by the size of the 'scratch' tape as all data of one generation must be on one tape at one time as card images (usually 29,000 maximum or less). A computer flow chart, the algorithms, the genetical assumptions, and a copy of the FORTRAN source language program are available from the author.
