STABILITY AND ADAPTABILITY OF NINE OPEN POLLINATED VARIETIES OF UB MAIZE
Open pollinated maize and two check varieties were evaluated in four locations, i.e. Malang, Jombang, Kediri, and Trenggalek regencies for two seasons from March to November 2009. The research objective was to determine stability and adaptability of the open pollinated maize. The experiment was cond...

Population UB4201 (5.1 t ha-1) was adaptable to productive environment, and UB4301 (5.8 t ha-1) was adaptable to marginal ones. http://agrivita.ub.ac.id/index.php/agrivita/article/view/27G × E interactionstabilityadaptationopen pollinated maize varietyUB line |
