Cytoplasmic effects on plant weight in crosses between flax genotypes and genotrophs

Abstract

Crosses were made between two flax genotrophs, L and S, and two other flax genotypes. With a given pair of parents and their reciprocal F1 hybrids, crosses were made in all ways to generate 16 different progenies. Progeny means for total plant fresh weight were examined. Cytoplasmic effects were detected in these progeny. No reciprocal F1 differences were found; cytoplasmic effects were seen as differences between the progeny of the one compared to the other F1 hybrid. Genetic and cytoplasmic effects were estimated by weighted least squares procedures. A depressant cytoplasmic effect was transmitted through the male gametes of S, while a positive effect was passed through the female gametes of L. © 1973 The Genetical Society of Great Britain.
