Evaluation for stigma receptivity in cytoplasmic male sterile lines of Brassica juncea L.Czern Coss

摘要

Field experiment conducted for two years indicated that the seven CMS lines of Brassica juncea differed for stigma receptivity. Stigma receptivity was recorded up to 10 days in Ogura, Moricandia and Erucoide ssystems. Peak stigma receptivity was observed two to three days after flower opening in case of Siifolia, Erucoides and Moricandia (green). It was suggested that Ogura and Moricandia (green) could be useful for hybrid development and seed production.
