Abstract

In crops improvement, comparison of promising lines with local cultivars can be effective for assessing breeding programs. In order to study the relationships between grain YIELD and some agronomic traits of RICE, a field experiment was conducted on seven promising RICE lines Shiroodi cultivar at in RICE Research Institute of Iran (Deputy of Mazandaran-Amol) 2005. The experimental design was randomized complete block with four replications. In this study 11 traits including grain YIELD and YIELD component, grain and plant morphological characters were measured. Results of analysis of variance showed significant differences among genotypes in terms of traits under study, which indicates the existence of genetic variations. Mean comparison showed that line 2 are better based on their YIELDs and some other traits. Grain YIELD showed was positively significant GENOTYPIC AND PHENOTYPIC CORRELATIONS with plant height (g=0.72**, p=0.64**), length panicle (g=0.78**, p=0.59**), weight panicle (g=0.81**, p=0.59**), number of filled grains (g=0.79**, p=0.55**) and flag leaf area (g=0.64**, p=0.5**). Overall results of this study showed that No. 2 line to the superior ratio Shiroodi cultivar for traits, flag leaf area, number of filled grains, weight panicle and length panicle.
