The field trial to study the growth and development of several potential hybrid corn varieties was carried out in the winter crop of 2012 and spring crop of 2013 with 8 different new hybrid corn varieties and the NK4300 variety used as a control. The trial was arranged with three replications using a random block design. The results of the experiment show that the duration of the trialed varieties falls in a range from 107-119 days (in winter crop of 2012) and 117-124 days (in the spring crop of 2013), which is suitable for the rotation crop pattern applied in winter and spring crops in Thai Nguyen province. The KK 11-6 appeared to have the worst plant falling resistant capacity with the evaluation score of 2-3. The other tested varieties indicate a good plant falling resistant capacity with the evaluation score of 1-2. The KK 11-3 and KK 11-11 varieties have a good resistant capacity to stem borers (the score of 1, as the same as the control). The actual yield of the tested varieties was from 60.95- 84.12 quintals/ha (in winter crop of 2012) and 61.53- 78.95 quintals/ha (in the spring crop of 2013). The KK 11-11 variety had the actual yield of 78.95-84.12 quintals/ha that was higher compared to the control at the 95 percent of confidence. The other varieties had the actual yield of 60.95-78.93 (in winter crop of 2012) and 61.53-72.77 quintals/ha (in the spring crop of 2013) that was the same as of the control, NK4300.
