摘要

Production and seed quality in peanut (Arachis hypogaea?L.) can be reduced substantially by?in situ?germination under unpredictable rainfed environments. Inheritance of fresh seed dormancy in Spanish x Spanish crosses was studied with two sets of segregating populations, an F2?population derived from true F1?hybrids identified with peanut microsatellites markers and other populations (F2, BC1P1Sand BC1P2S) from randomly-selected F1?individuals. In the F2?population developed with true F1?hybrids, the chi square test was not significant for the deviation from the expected 3:1 (dormant: non-dormant) ratio. In addition, the bimodal frequency distribution curve with the F2?population gave more evidence that fresh seed dormancy is controlled by a single dominant gene. The average frequency (48%) of true F1?hybrids give evidence that deviations from expected ratios in the populations (F2?and BC1P1S) developed from non-tested F1?individuals, is most likely due to inadvertent selfs. This study emphasized the need to identify with molecular markers the cross progenies in self-pollinated crops as peanut before testing for any trait.
