  • Cytoplasmic male sterility system for species and its use for hybrid seed production in indian oilseed mustard
    Patent number: 8030548
    Abstract: A cytoplasmic male sterility (CMS) system in different Brassica species having a distinct mitochondrial DNA specific RFLP signature. A method for obtaining male sterile lines and restoration of fertility in B. juncea for hybrid seed production using the CMS. This CMS in B. juncea can be restored by crossing male sterile plants with any B. juncea genotype other than the maintainer genotype. The same B. juncea genotype acts as maintainer of male sterility after a specified number of backcrosses. The CMS also relates to histological characterization of another and microspore development in B. juncea.

  • Novel Cytoplasmic Male Sterility System for Brassica Species and its Use for Hybrid Seed Production in Indian Oilseed Mustard Brassica Juncea
    Publication number: 20080148429
    Abstract: The present invention relates to a novel cytoplasmic male sterility (CMS) ‘126-1’ system in different Brassica species and a method for obtaining male sterile lines using the said CMS. The CMS has distinct mitochondrial DNA specific RFLP signature. The invention also relates to a method for obtaining male sterile lines and restoration of fertility in B. juncea for hybrid seed production. This CMS in B. juncea can be restored by crossing male sterile plants with any B. juncea genotype other than the maintainer genotype. The same B. juncea genotype acts as maintainer of male sterility after a specified number of backcrosses. This invention also relates to the histological characterization of anther and microspore development in B. juncea.

  • Novel 'oxy' CMS brassica napus corrrected for chlorosis using hexaploid bridging material generated through protoplast fusion and a method of producing the plant
    Publication number: 20030110538
    Abstract: The present invention relates to a novel cytoplasmic male sterile (CMS) Brassica napus plant containing improved ‘oxy’ cytoplasm i.e. chloroplast from Brassica oleracea and recombinant mitochondria from Brassica oxyrrhina, a process for developing the said ‘oxy’ CMS Brassica napus plants by using hexaploid ‘oxy’ CMS Brassica plants, obtained through somatic hybridization, as the bridging material and backcrossing these for at least five generations to transfer the novel ‘oxy’ CMS character to Brassica napus plants and a method for producing the improved hexaploid male sterile ‘oxy’ CMS Brassica plants mediated through protoplast fusion and regeneration of the somatic hybrids and to the transfer of this improved ‘oxy’ cytoplasm to tetraploid Brassica napus (AACC) plants through conventional backcross breeding for five generations.
