Effect of processing stages on seeds quality, growth and yield characters for some rice cultivars (Oryza Sativa L)

摘要

This study was conducted at the Farm of Rice Research Section, FCRI, ARC Egypt, during 2016 and 2017 summer seasons, were used in factorial design with three replications to study The effect of processing stages for some rice varieties on seeds quality, growth and yield characters of some rice varieties four rice verities, Giza 177, Giza 178, Sakha 104 and Sakha 106 different processing stages. The data were recorded on 1- Laboratory characters i.e.,, 1000 grain weight, Grain volume, Germination index, 2- Growth characters i.e.,, Plant height, Days to heading, Flag leaf area, 3- Yield characters i.e.,, Number of panicles/plant, Panicle length, Seed set %, Panicle weight and Grain yield,. The results showed that, the processing stage number six recorded the highest values for the studied characters comparing to the other stages, sakha 106 recorded the highest values for most the studied traits except Giza 178 recorded the highest value for grain yield, From the above results could be concluded that to get high seed quality of rice varieties should be using the seed from six stage of the processing stages with different rice varieties or fourth stage which recorded the mean desirable values for yield characters.
