Abstract

In the process of hybrid RICE seed production program, initial assessment of the traits related to out crossing levels in male sterile lines for selecting the favorite lines is necessary. Therefore, the study of seven cytoplasmic male sterile lines (released by IRRI) together with their maintenance and 33 male sterile lines derived from backcrossing program (released by Iran) were compared using a randomized complete block design with three replication. Analysis of variance indicated significant differences among the studied lines in 1% level for all characters. Mean comparison of traits showed that male sterile Hasani-awn-Red has the longest length of stigma (2.93 mm) and shortest length of anther (1.87 mm). Out crossing percent was very low in Hasani-awn-Red A and the Khazar A lines. IR69224A line with complete pollen sterility, had out crossing percent (`x=%37.79). Pollen sterility, number of florets per panicle, legume and stamen length traits have been high genotypic coefficient of variation, inheritance, genetic progress. These traits can be used as selection criteria for cytoplasmic male sterile lines without high crossing. Also, out crossing with traits such as anther length (r=0.47), panicle exertion rate (r=0.32) and floret length (r=0.22) had a significant positive correlation. Thus cytoplasmic male sterile lines with anther length large, floret size and complete panicle exertion will be more products of hybrid seed.
