Anther culture of groundnut (Arachis hypogaea L.): I. Categorization and selection of flower buds (1)YSudhakarauthorJ PMossauthorFlower buds from three varieties of groundnut, Robut 33-1, TMV 3, and ICGS 11, growing in the field and one variety, Robut 33-1, growing in the glasshouse, were collected at different times after sowing and the size of the flower buds, colour of the anthers, and the genotypes were correlated with the stage of anther development. Significant differences were observed among sizes of anthers containing pollen at different stages of development. These sizes differed at the beginning and end of the flowering season, but the correlation of anther colour with the stage of development was independent of the time of flowering. The observations showed that anthers could be harvested for culture by standardizing the sizes of flower buds one day earlier, and by collecting buds only of sizes corresponding to the desired stage (the non-overlapping zone of the graph)Groundnut1990Société d'éditions techniques continentalesArticle
