In a plant breeding program, knowledge of the character and interrelationships among yield and yield contributing characters are necessary. This study was carried out to identify the plant character and its correlation between yield-correlated traits of 35 NPT rice promising lines with Ciherang and Sintanur as check varieties, planted in two locations, Bogor and Pusakanagara and two seasons (2009 dry and wet season, DS-WS). Those lines were planted in Randomized Complete Block Design (RCBD) arrangement, in three replications. The 21-days-old seedling planted one seed per hole, spacing 20 cm x 20 cm, with a plot size of 2 x 5 m2 per line. Plant characters varied and were significantly different from Ciherang and Sintanur as check varieties except for grain yield. B11742- RS*2-3-MR-34-1-2-1 was the line that had the lowest plant height, grain yield, and the shortest growth duration. Most of the lines had character as new plant type variety. Grain yield positively correlated with all characters, but only significantly and positively correlated with plant height at range from 91.4- 120.7 cm.
