Simple Sequence Repeat (SSR) markers were used to investigate the variations between drought sensitive and drought tolerant genotypes. Patterns obtained using RM328 and RM302 detected polymorphism between T14, T15 and Amber33, Amber Baghdad genotypes and those obtained using RM316 and RM201 for the tested genotypes suggested that these primers may have the ability to produce drought tolerance markers. According to the patterns obtained using RM189, RM3825 and RM212 primers indicated that these primers cannot be relied on as markers for drought tolerance.

A novel floral organ mutant of rice (Oryza sativa L. subsp. indica), termed pistilloid-stamen (ps) here, has flowers with degenerated lemma and palea, with some stamens transformed into pistils and pistil–stamen chimeras. Genetic analysis confirmed that the ps trait is controlled by a single recessive gene. F2 and F3 segregation populations derived from PS ps heterozygote crossed with Oryza sativa subsp. indica 'Luhui-17' (PS PS) were used for molecular mapping of the gene using simple sequence repeat (SSR) markers. With 97 recessive individuals from an F2 segregation population, the ps locus was preliminarily mapped 6.2 cM distal to marker RM6324 and 3.1 cM proximal to marker RM6340 in the terminal region of the short arm of chromosome 1. With a large F3 segregation population, the gene was fine-mapped between markers RM6470 and RM1141, at distances of 0.10 and 0.03 cM to each marker, respectively. The position of the ps gene was finally located within a 20 kb physical region containing 3 annotated putative genes. One of them, encoding a protein with a single C2H2 zinc-finger domain, may be the candidate gene for PS.Key words: rice (Oryza sativa L. subsp. indica), pistilloid-stamen mutant (ps mutant), molecular marker, simple sequence repeat (SSR), gene mapping
