ABSTRACT
Flowering Chinese cabbage also called 鈥楥aixin' or "Choy sum" is an annual leafy vegetable of the 鈥楤rassicaceae' family. An experiment was conducted with eight flowering Chinese cabbage genotypes using RCBD with three replications at 鈥楽her-e-Bangla Agricultural University' (SAU) to characterize the various yield contributing traits, evaluate genetic variability and interrelationship between various traits. A significant difference was found for different characters among the flowering Chinese cabbage genotypes. Days to maturity, fresh yield per plant, plant height, no. of siliqua per plant and seeds per siliqua displayed higher genotypic variance suggesting the existence of great variability for these traits. High heritability plus high genetic advance in per cent of mean was detected for fresh vegetative yield, no. of silique per plant indicating additive genetic effect. Fresh yield of flowering Chinese cabbage exhibited a significant and positive relationship with length of leaf and plant height while with days to 50% flowering, leaf breadth and no. of siliqua per plant at phenotypic level only. Our results indicate that selection based on these characters could be rewarding. Besides, this is the first report for cultivation of flowering Chinese cabbage in Bangladesh and further improvement can be performed for this crop.
