Resumo: The extension of natural hybridization on pigeon pea was evaluated on individual plants and on plants in a row, using two different genotypes and two planting times at Petrolina, State of Pernambuco, Brazil. The color of the stem was used as a genetic marker due to the simple inheritance and the complete dominance of the purple color over the green color. The natural hybridization was higher in the second harvest than in the first one and also higher on individual plants than on plants in a row. Significant differences were not found in the natural hybridization between the two genotypes and also between the two planting times. The natural hybridization rate varied from 2.50% to 13.36% for individual plants and from 0.86% to 2.24% for plants in a row.

Foi usada a cor do talo como marcador genético, devido à herança simples e à dominância completa da cor violeta sobre a cor verde. A hibridação natural foi maior na segunda colheita em relação à primeira, também a hibridação em plantas individuais foi superior à observada em plantas de uma fileira. Não se observaram diferenças marcantes na hibridação natural entre os dois genótipos, nem entre as avaliações efetuadas em diferentes épocas do ano. As taxas médias de hibridação natural que foram observadas oscilaram de 2,50% a 13,36% nas plantas individuais, e de 0,86% a 2,24% nas plantas de uma fileira.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraF.
