| Abstract | Stable genic male sterility (GMS), which is not influenced by environmental factors, has not been used for F$_{1}$ hybrid seed production because male-sterile inbred lines cannot be developed and male-sterile plants must be selected from segregating populations every time. However, the stability of male sterility may provide a reliable system for F$_{1}$ seed production without contamination of selfed seeds. A genic male-sterile mutant in rice (Oryza sativa L.), C204, which was selected from progeny of the cultivar ‘Koshihikari’ irradiated by gamma rays, has shorter and whiter anthers than those of ‘Koshihikari’ and has no pollen grains. Segregation analysis of C204 suggested the male sterility of this mutant to be controlled by a recessive allele of a single gene. Linkage analysis of a mutated gene responsible for the male sterility revealed the gene to be in a region of ca. 75 kb on the long arm of chromosome 9. The nine genes predicted in the 75-kb region were sequenced, and compared with the published Nipponbare genome sequences. A single-base deletion was found in the first exon of a C204 allele of Os09g0493500, which encodes an NAD-dependent epimerase/dehydratase family protein, resulting in a frameshift causing a premature stop codon. A dot-blot single nucleotide polymorphism marker for detection of the single-base deletion in Os09g0493500 was developed. We herein propose an F$_{1}$ hybrid seed production system using stable GMS with a simple selection method of GMS plants. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
