Selecting Best Rice Varieties under Drought Stress and Non-Stress Conditions Using Selection Indices
Abstract
Grain yield and most of the
traits that have economic importance in plants, herited as quantity and using
direct selection method have not large progress. So, one of the most effective
method's indirect selections as improve grain yield with a trait effective on
it, is using of selection index. In this research, 42 Iranian local and
improved rice varieties were evaluated in randomized complete block design with
three replications under two separate conditions, normal irrigation and drought
stress during 2014 and 12 traits were measured. Estimating 10 different
selection indices based on optimum and base indices in both conditions
indicated that selecting for grain yield per plant, 1000-grain weight, number
of filled grain per panicle, canopy temperature and number of panicles per
plant in non-stress condition and grain yield per plant, 1000-grain weight and
number of total spikelet per panicle in stress condition by using their path
direct coefficients as economic weights would be a suitable selection criterion
for improving of population. Results distinguished that selected varieties
based on optimum and base indices in both conditions are almost similar. Thus,
optimum and base indices in non-stress condition are proposed as a criterion
for selecting high-yield vrieties to use in stress conditions.
