Abstract

In order to study the value of early generation bulk yield testing for predicting the yield potential of crosses In later generations, 21 groundnut crosses (In F₁, F₂ and F₂ generation) were studied in a replicated bulk yield test during post rainy season of 1995 and rainy season of 1996. Positive and significant correlations between kernel yields of bulk F₁ Vs F₂ and F₂ Vs F₃ generations indicated that yield test of an early generation bulk of groundnuts can be used for identification of potential crosses in early generations. The relative ranking of crosses either in F₁ and F₂ (or) F₂ and F₃ (or) both tests was found to be a suitable Index to decide whether a cross should be persued or discarded in early generations.
