Cross Pollination

Studies of the floral biology of canola were accomplished with the objective of enlarging the system and reproductive strategies knowledge of its CTC-4 cultivar in Dourados, Centerwest, Brazil. Brassica napus is self pollinated, presenting however, many resources for the allogamy accomplishment, e.g., abundant pollen, nectar and scent production. The smaller anther were responsible for the production of fruit with smaller and less growth seeds, when compared to the autogamy, autopollination and cross pollination tests.

Planning the artificial pollination of agricultural crops requires knowledge of the floral biology and reproductive system of the crop in question. Many studies have shown that rapeseed (Brassica napus Linnaeus) is self-compatible and self-pollinated, but its productivity may be increased by insect visitation. In the present study, the floral biology and the response of productivity to insect visitation of two rapeseed cultivars (Hyola 420 and Hyola 61) were analyzed and compared in three regions of Rio Grande do Sul, Brazil. The rapeseed flowers presented three stages during anthesis, with the time periods varying between the cultivars. Both cultivars are self-compatible, but free visitation of insects increased productivity by 17% in the Hyola 420 cultivar and by approximately 30% in the Hyola 61 cultivar. Therefore, it is concluded that the cultivar Hyola 61 is more dependent on insect pollination than Hyola 420.
