Abstract

The relationship between agronomic traits and molecular markers in Rice using 21 and 144 characters band consists of 10 pairs of markers in 59 genotypes of Rice were studied. Irrigation was performed as flooding in both environments, normal and drought from transplanting to a maximum of tillering. Then, to create tension, 40 days after transplanting (the maximum tillering) by the end of the season to 25 days. The highest polymorphic information content (PIC) detected for ISSR-7 with 0. 49 and lowest PIC were recorded for ISSR-2, ISSR-8, ISSR-9 and ISSR-10 markers with 0. 47. The Based on regression analysis of molecular data and morphological traits, 70 and 72 alleles were distinguished for normal condition and drought conditions for morphological traits, respectively. The highest positive Markers (6 alleles) belong to flag leaf width in normal conditions and flag leaf width, number of filled grains, number of grains per panicle and yield have the highest positive markers (9 alleles) in drought conditions. ISSR6-7, ISSR10-11, ISSR7-4, ISSR1-7 ISSR2-5, ISSR8-9, ISSR4-8, ISSR1-5, ISSR1-2, ISSR5-1 explained phenotypic variations of days to flowering in normal conditions (20%). ISSR2-8, ISSR9-ISSR1-6, ISSR10-8, ISSR10-10, ISSR3-1 explained phenotypic variations of grain yield in drought conditions (17%). Some of the markers related to several traits. The result of this study will provide useful information for indirect selection of traits associated.
