Combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. Parents and hybrids differed significantly for general combining ability (GCA) and specific combining ability (SCA) effects, respectively. The variance due to GCA and SCA showed that gene action was predominantly additive...

canola has industrial applications as well as edible usage. in regard to 15.8 kg oil per capita usage and vast oil importing, cultivation development of oil seeds is a major issue. this study was performed to determine the best sowing date and cultivars for canola as means of seed yield and oil percent improvement in dehloran region of elam province. 25 treatments were used in a split plot expe...

in order to determine the effect of vernalization on phenology and development rate of canola varieties, an experiment was conducted at research farm of gorgan university of agricultural science and natural resources during 2005-2006. the experiment was a randomized complete block design arranged in split plot with four replications. six varieties of canola (option500, rgs003, hyola308, hyola60...

functional response, as describing the rates of predation in different prey density, and determining the predator efficiency, is important in the regulation of prey populations. the functional response of male and female adult of lady beetle, hippodamia variegata, was studied at different densities of green peach aphid under laboratory conditions on canola brassica napus l. (cv. rgs003). nymphs...

inheritance of yield and its contributing characters in rapeseed (brassica napus l.) was studied in a 8×8 diallel cross through griffing and jinks-hayman analyses. both general combining ability (gca) and specific combining ability (sca) were highly significant for seed yield, seed weight and branches per plant, while only gca for seeds per pod and oil content and only sca for pods per plant an...
