  1. aDirection of phenotypic effect; M and P indicate MASARB25 and Pusa Basmati 1460 alleles, respectively. Additive effect is the effect of substituting a MASARB25 allele for a Pusa Basmati 1460 allele; Its positive value indicates that MASARB25 has the positive allele; LR: Likelihood ratio, LOD: log10 of an odds ratio, R2: percent phenotypic variance.
