Impact of Different Mating Approaches in Generating Variability in Wheat (T. Aestivum L. Em Thell)

Comparison of mating systems indicated the significance of biparental mating witbin F₂ and intermating between individuals of two different F₂ populations for elevating the populations mean and initial genetic variation for grain yield and Us component trails in wheat. Correlation studies also demonstrated the usefulness of intermating. Positive and significant correlations were established between tillers/plant and grains/ear in BIPS and F2₁ intermated populations also showed positive and significant correlation between 1000-grain weight and grains/ear. Double-cross F₂ populations showed little significance.
