Diallel analysis for grain yield and yield components in <em>Phaseolus vulgaris</em> L.
Abstract
Six common bean (Phaseolus vulgaris L.) cultivars and their 15 possible diallel hybrids were assessed for combining ability of yield and its components. A random block design was used with ten replications, in the state Paraná in 1997. Diallel analysis according to Griffing (1956) was used which indicated the predominance of additive gene effects for total number of pods per plant and mean seed weight characteristics. However, mean number of seeds per pod and grain yield characteristics, there was equivalence of the additive and non-additive gene effects. The Rudá, Aporé and Campeão-1 cultivars are indicated for obtaining superior genotypes by intrapopulation breeding from the estimates of the combining abilities for grain yield. The combinations LPSPI 93-19 x Rudá, Rudá x Campeão-1, FT-Nobre x Aporé, LPSPI 93-17 x FT-Nobre, and LPSPI 93-17 x Aporé, showed greater potential for generating promising segregantsDownloads
