Gynomonoecy in Chenopodium quinoa (Chenopodiaceae): variation in inflorescence and floral types in some accessions


Inflorescence structure and floral morphology has been studied in 19 accessions of C. quinoa. All the accessions show gynomonoecy and bear three basic flower types viz. hermaphrodite, chlamydeous female and achlamydeous female and number of types can be extended to five considering the size of flowers. Ten types have been classified on the basis of the proportion of hermaphrodite and female flowers and their arrangement, depending upon the number of divisions of the dichasium on the glomerule. Implications of these results in facilitating intervarietal crosses are discussed.
