Revealing the genetic inheritance of elongated uppermost internode (eui) gene in spontaneous mutant of rice (Oryza sativa L.)
Abstract
Success of hybrid rice breeding technology is solely depend on hybrid seed yield. Due to incomplete panicle exsertion, use of gibberlic acid (GA3) spray at proper stage with proper dose enhances the panicle exsertion rate in male sterile lines which incurred huge cost on hybrid seed production in rice. This is the reason for low deployment of hybrid rice in farmer field. To overcome this expenditure, there is a need of CMS lines with complete panicles exsertion. The spontaneous mutant, Accession 18 shows elongated uppermost internode trait but it is treated as unknown donor, hence inheritance of this mutant line is compared with known eui gene donor, IR91-1591-3 to investigate the allelic relationship between the available genotypes. A spontaneous mutant Accession 18 possesses elongated uppermost internode traits based on the inheritance and allelic relationship with eui gene donor, IR91-1591-3. The eui gene follows mendelien inheritance of single monogenic recessive as it segregates 3:1 ratio of non elongated and elongated trait.
