dc.description.abstractSouthern rust is considered as a tropical disease reducing corn (Zea mays L.) production. We found similar symptoms at Kunwi Farm in 2006. We have carried out four sets trials of Silage 1 (69B x P45) and Silage 2 (51B x P45) in Jeju and Kunwi in 2008 and 2009, respectively. Materials of P45, 69B and 51B were obtained from Kyungpook National University (KNU) gene bank to develop resistant inbred lines. We used a possibility random mating to all genotypes. Field experiments were designed in a RCBD with three replications. Important agronomic traits were rated and analyzed with SAS 9.1 program, 2005. In Jeju, Southern rust infection was confirmed with highly significant different (P=0.001) for both Silage 1 and Silage 2. The infection was highly positive correlation (y=1.565 + 0.708x; r2=0.433 and y=2.468 + 0.483x; r2=0.358) with commercial value for Silage 1 and Silage 2, respectively. In Kunwi, the disease was also confirmed with significant (P=0.041) and highly significant (P=0.001) different for Silage 1 and Silage 2, respectively. The infections were low (y=2.337 + 0.372x; r2=0.202) and highly (y=1.596 + 0.517x; r2=0.371) positive correlation for Silage 1 and Silage 2, respectively.
