Effect of different modes of pollination on quantitative and qualitative parameters of radish seed crop

The present study was conducted at C C S Haryana Agricultural University, Hisar, Haryana (India). A total of 18 insect species visited radish flowers out of which viz. out of which 10 belongedto hymenoptera, 5 to Lepidoptera, and 3 to Dipteran. Among these, Apis mellifera L., A. dorsata F., A. florea F., A. cerana F. and syrphid fly were found to be the most frequent pollinators. Effect of different modes of pollination on yield and seed quality parameters of radish showed that number of siliqua/plant, siliqua length (cm), number of seeds/siliqua, seedling length(cm), seed vigour-I, seed vigour-II, test weight (g), dry seedling weight (g) and germination (%) was significantly higher under open-pollination (5.2, 1076.1, 6.8, 35.8, 3462.7, 11.5, 11.6, 0.118 and 96.7, respectively) as compared to under without insect pollination (3.4, 430.5 3.3, 14.4, 1378.1, 5.9, 7.2, 0.091 and 65.3, respectively).
