Linkage between loci controlling nodulation and testa variegation in peanut

Article Abstract:

Linkage of loci controlling nodulation and testa variegation was examined for cultivated peanut. The main objective of this study was to determine whether the gene controlling testa variegation was linked to a gene or genes controlling nodulation.

Inheritance of a shriveled seed trait in peanut

Article Abstract:

The seed shriveling trait in peanut, Arachis hypogaea L., is controled by a recessive gene that determines lipid deposition and seed morphology. Crosses between normal-seeded cultivar, Sunrunner, and three shriveled seeded lines are conducted to determine the inheritance of this trait. Segregation of this trait is observed in F(sub 4) generation when the female parent carries the shriveled character, but if the male parent is the shriveled line, the segregation occurs in the F(sub 2) generation. The genomic imprinting or male transmission of extrachromosomal factors may cause this effect.
