  • * Scored flowers were selected between the first eight arising flowers of wild-type, 10.1 and 29.1 plants grown under SD conditions. Numbers are means± standard deviation

  • Number of flowers at stages 1-3 per primary inflorescences were counted. Wild-type, 10.1 and 29.1 plants were grown under LD photoperiod. Three primary inflorescences per day and per line were analyzed. Numbers are means ± standard deviation
