Abstract
Abstract One of the obstacles in increasing corn production is the attack of Spodoptera frugiperda. The resistance of each maize variety to this pest attack varies greatly. This research aims to obtain local types of maize that are resistant to attacks by corn armyworms. The research was conducted in Kediri, East Java. The research used a Complete Randomized Block Design with treatment of various maize varieties local and with rivers. The varieties tried consisted of Kebo Bima, Lameran-Latim, Madura Kuning, Madura Putih, Manik Liu, Seraye-Bali and Sumbawa. The results showed that there was no difference in plant height between all the local corn varieties tested, while the highest number of leaves was produced in the Madura-kuning and Madura-putih varieties. The Manik-Liu variety produces the smallest leaf length and leaf angle compared to other varieties, while the widest leaves are produced by the Sumbawa variety. The flowering period and harvest time were the longest for the Manik-Liu variety, while the fastest for the Kebo Bima variety. The highest shoot root ratio was produced in the Seraye-Bali variety. Based on the maize of grains yield per hectare obtained, the Sumbawa and Seraye-Bali varieties are the most resistant varieties compared to the others and able to provide the highest maize seed yield per hectare.
