Study on Dedifferentiation Characteristics from Wheat Anther in Various Generations of Hybrid

doi:10.3321/j.issn:1000-7091.2004.04.020

Abstract

Abstract: Five hybrid combinations of wheat are used to evaluate the effects of genotypes on anther culture response in F₁, F₂, F₃filialness. T he following results are acquired. Induction frequency of pollen callus, differen- tiation frequency of green plantlets, callus fresh weight from different wheat genotypes have a significant differ- ence in same generation of hybrid, but induction frequency of pollen callus, differentiation frequency of green plantlets, callus fresh weight from same wheat genotypes have a slight difference in different generations of hy- brid. There are significant correlation between induction frequency of pollen callus and differentiation frequency of green plantlets. Two hybrid combinations from parent Shi4185 have more induction frequency of pollen callus and more differentiation frequency of green plantlets in F₁, F₂, F₃ filialness, so Shi4185 is an ideal bridge parent of anther culture breeding.

Key words: Wheat, Anther culture, Genotype, Generation of hybrid
