Estimation of Genetic Variance and Heritability of F2 Populations of Corn Plants in Dry Land

This study was aimed to determine the genetic variance of several F2 population traits maize, broad heritability values and phenotypic correlations between yields other quantitative traits. The method used is experimental method. experiment designed in a randomized block design, with 6 replications. number treatments 4 populations, namely F2, Sinta Unram, hybrid NK212 NK7328. Each planted rows, each consisted 40 plants. observed characteristics included plant height, leaf per plant, angle, ear length, diameter, weight dry harvested yield (dry seed plant). data were analyzed by simple statistical analysis at 5 percent level significance. results showed that cob harvest higher than Unram's diversity relatively wide diversity. length diameter also Unram; but quite narrow. population's same as Unram category. value meaning classified high (> 50 %) obtained on leave yield; while angle moderate. Harvested cobs strong correlation (0.827); properties are very weak Improving can be done indirect mass selection using selected trait
