          Abstract

          Com a finalidade de obter informações sobre genes marcadores, foram hibridadas, manualmente, linhagens de crotalária contrastantes em relação à cor no hipocótilo, na base das asas das flores e das sementes. As sementes das gerações paternais, de F1, F2 e do retrocruzamento para o pai recessivo, foram semeadas em casa de vegetação para o estudo da segregação. Verificou-se que a presença é dominante em relação à ausência de pigmentação com antocianina, que a herança deste caráter é monogênica e que há efeito pleiotrópico entre sementes pigmentadas, pinta púrpura na base das asas das flores e hipocótilo roxo. Aventou-se a existência de polimeria na geração F2, uma vez que dentro das plantas com sementes pigmentadas foi possível a separação das sementes em cinco classes de intensidade de coloração. Sugeriu-se o símbolo Aa - para presença e aa aa - para ausência de pigmentação como discriminante do referido lócus.

          Translated abstract

          In order to obtain information about gene markers, crosses were made between contrasting lines in relation to the pigmentation of hipocotyl, base of the flower wing and seed coat. Paternal, F1, F2 generations and backcross to recessive female parent were cultivated in the greenhouse. The inheritance was monogenic. The presence of anthocyanin pigment was dominant in relation to the absence. There was a pleiotropic effect among pigmented seed, purple stain at the base of the flower wing and purple hipocotyl. It was possible to separate five classes of pigmentation intensity among the plants with colored seeds, indicating the possibility of occurrence of polymeria in the F2 generation. A symbol Aa - was suggested for the presence and aa aa - for the absence of anthocyanin pigment to discriminate the locus.
