ARTIFICIAL CROSSES IN OAT

The present work aimed at testing different artificial cross technique s in Brazilian oat (Avena sativa L.) genotypes. Crosses comparing the approaching method, cut flower, and open flower techniques were made i n a greenhouse during 1989, 1990, and 1991. A completely randon design was used in the first experiment, and a randomized complete-block des ign was used in the other three experiments. Analyses of variance were made using the modified data from the percentage of grain obtained. A mong the techniques tested, the approaching method was superior under adequate temperature. All techniques were similar under stress conditi ons.
