Rice is a cereal plant and staple food for most Indonesian people. One of the causes of the problem is decrease of wetland and lowland area which have impact on national level production. One of the efforts to increase rice production is selection to get desired trait. Regression and correlation analysis to determined the relationship among characters that can be used as a consideration for selection criterion. The purpose of this study is to know the relationships between morphological and agronomic characters in rice plant of F2 generation. This study was conducted at the Experimental Faculty of Agriculture, University of Brawijaya, Jatimulyo Village, Malang, between June and August 2018. Planting materials were population of F2 generation (SBCH, SBCB, TWCH dan TWCB). All of the populations planted in area 25 m x 3 m with spacing 60 cm x 60 cm. Based on the result, all of the populations showed that there was positif linear relationship between plant height and panicle length, number of tiller, and number of productif tiller. TWCH population showed strong and significant positive correlation in leaf length and number of tiller. Very strong and significant positive correlation showed by all of F2 generation in plant height with panicle length and number of productive tillers with number of tillers.
