HARN, Chargyawl (Coll. of Agr., Chonpuk National Univ.) Development of sporangia and gametophytes of the Brassica pekinensis, Raphanus sativus and their intergeneric hybrid (aRF_1). Kor. Jour. Bot. VI(1): 1-7, 1963.
Two individuals of intergeneric hybrids in the crossing of Brassica penkinensis ♀× Raphanus sativus ♂ were obtained, and among the three kinds of plants, Brassic, Rphanus, and F_l, comparison on the mega- and microsporogenesis, megagametophyte formation, and morphological changes in the developing sporangia, etc., were made.
Differences between Brassica and Raphanus were observed in the shape of mega- and microsporangia, their changes in development, and the formation of megagameto- phyte.
Sporangia of the F_l plants, until pre-meiotic stage, show intermediate, maternal, patenal, or vigorous inclination, and the difference of these characteristics when compared with those of the parent is slight.
Meiotic irregularity resulted from the intergeneric hybridity of F_l plant gives rise to the abnormal mega- and microspore and accompanied abortive female and male gametophytes, bringing about the remarkably differences from its parent in the morphological changes of the developing mesa- and microsporangia.
