Nine open-pollinated varieties and SW 1 (MMS)C2F2 using as a check were tested for yield stability during rainy season 1987. Treatments were arranged in a randomized complete block design with 4 replications at each location. Individual plot consisted of 4 rows of 6.5 m. long with the spacing of 75 cm. between rows and 25 cm. between plants. Plants were thinned to 1 plant per hill. Data were statistically analyzed employing method described by Eberhart and Russell (1966). The experiments were conducted in different environments named Nakhon Sawan Field Crops Research center, Phraputhabath Field Crops Experiment Station, Banmaisamrong Field Crops Experiment Station and National Corn and Sorghum Research Center. The deviation from regression mean square (s2d) was more important for estimating yield stability than regression of the varietal mean on environment index (b). The NS 104 and SW 1 (MMS)C2F2 (Check) produced consistently high yield over the tested environments.
