Abstract

In order to study QUALITY TRAITS among 10 PROMISING LINEs and 4 cultivars including Tarom Hashemi, Kaduos, Bahar1 (Hybrid) and Nemat, A field experiment was carried out at RICE Research Institute of Iran (Rasht) during 2008. Considered lines in this study were results of hybridizing of Nemat variety that were considered as maternal parent by any of local good quality varity as paternal variable parent. The experiment was laid out in randomized complete block design with 4 replications. QUALITY TRAITS such as amylose content, gel consistency, gelatinization temperature, length and width, shape, grain elongation and aroma were evaluated after harvesting and milling in lab. According to the results, there was significant differences between PROMISING LINEs and control varieties based on all of the studied traits. Line 223 had high quality because was classified in medium amylose (22.3), medium gelatinization temperature (4.63 score), good grain elongation. This Line, however, didn' t show significant differences compared to Bahar1 (Hybrid) in terms of aroma trait. In spite of the highest yield (by 6736.6 kg/ha) in Line 415 but its QUALITY TRAITS were low when compared with other lines. Also, Lines 108 and 209 showed same physico-chemical properties and were aromatic. According to orthogonal comparisons, grain elongation in local varieties was more than improved varieties. There were positive and significant correlations among amylose content and gelatinization temperature with GRAIN YIELD. However, several traits such as length of cooked and grain elongation showed negative and significant correlation with GRAIN YIELD. Finally as a result, lines with high QUALITY TRAITS had lower GRAIN YIELD.
