Abstract

JASSO-BOBADILLA, Gerardo et al. Use of Opstat to validate results in a partial diallelic with eight corn lines evaluated in an environment. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.1, pp.41-52.  Epub May 02, 2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i1.3097.

Sampling procedures in a partial diallelic experiment applying the method of Kempthorne and Curnow (1961) to eight corn lines (S7) derived from the same variety, each used in five crosses (s= 5), are described. For the 20 single-cross hybrids, the calculations to obtain the analysis of variance for an environment with a randomized complete block experimental design with four repetitions are indicated. The effects between crosses are divided into general and specific combining ability using matrix algebra, the effects of gi and Sij are estimated, for each parent and in each cross, respectively. In addition, the components of variance and heritability are calculated in a broad and narrow sense. At all stages, it is indicated how to verify the calculations using a desktop calculator and, finally, the results are validated using the Opstat statistical package.

Keywords : circulant matrix; combining ability; heritability; incomplete diallelic.
