Abstract

This experiment was conducted to study the most effective morphological charactristics on RICE yield with ten genotypes of RICE at RICE Research Institute in Mazandaran (Amol) in 2005 on the basis of a randomized completly block design with three replications. Genotypes included eight new lines and two cultivars (Fajr and Neda) as control. Some criteria were studied such as biological yield, leaf area index in flowering stage, number of tiller, plant height, number of active leaves after flowering, flag leaf area and its effect on grain yield, HARVEST INDEX and 1000-grain weight. According to the results, RICE genotypes made a significant difference on grain yield, biological yield, HARVEST INDEX, number of tiller, plant height and flag leaf area but had no insignificant difference on 1000-grain weight, number of active leaves and quantity of flag leaf chlorophyl. Among these genotypes, line 106 and line 104 hade the most and the least grain yield, respectively. Line 106 had a higher mean of 1000-grain weight, a larger number of active leaves after flowering, higher biological yield, shorter height of plant and greater chlorophyl in comparison to other genotypes. Considering the results of the current study it is possible to introduce some charactristics such as the biological yield, 1000-grain weight and the area of flag leaf as effective factors on RICE grain yield.
