Abstract

In order to evaluate the relationship between quantitative and qualitative features with yield, ten PROMISING LINEs of RICE with Hashemi and Kadous races as checks were compared at Iran RICE Research Institute in Rasht during 2006, 2007 and 2008. The experimental design was randomized complete block design (RCBD) with four replications for all three years. In this study, eighteen features including yield and quantitative and qualitative traits were assessed. According to the results of mean comparison in respect of yield, Kadous race with 5426 kg/h showed the highest yield and lines No. 3,8 and 9 with 4450, 4435 and 4378 kg/h respectively showed the highest productivity. Estimating of simple CORRELATION COEFFICIENT among the features based on 3 years average manifested that the highest positive significant CORRELATION COEFFICIENT with yield was for 100 seed weight and tiller number. There was a negative significant correlation between yield and plant height. In the FACTOR ANALYSIS of the features, generally five independent factors justified 84% of the total variances. These five factors were, shape and size of the seed, morphological features of the plant, cooking quality and yield and its components. Meanwhile, the forth and fifth factors were so important to increas the yield. Therefore, the features of these factors including, 100 seed weight, seed per panicle, days maturity and seed length important in selecting the lines with desirable yield. Features such as days to heading, plant height, panicle length, milling quality, glutinization consistence, glutinization temperature and seed weight had less importantance.
