STATUS ON HETEROSIS BREEDING IN LAST TWO DECADES OF INDIAN MUSTARD: A REVIEW

Indian mustard (Brassica juncea) is primary cultivated for oil seed production in India. Development of line varieties is the predominant factor in mustard crop. In last two decades developed hybrids for commercial perspective and improve quality purpose. Heterosis is superiority of one or more traits in F1 hybrid over its parents. Heterosis breeding is largely used to improve crop productivity. Varietal selection is play a vital role in heterosis breeding. In plant breeding technology germplasm of parental genotype is most important and we need to develop more crop varieties of high yielding and high-quality parameters of Indian mustard crop. CMS is a fertility restore system help to develop hybrids. NRCHB506 is first CMS based developed hybrid by DRMR. Mori candia cytoplasmic male sterility (CMS) is used for heterosis breeding in mustard met with success to develop varietal technology and research would be the enhancing to release new varieties which are tolerant to biotic and abiotic stress it includes developing agronomical traits with help of genetic engineering of transgenic genes and identified specific traits of genes in genome. In transgenic genetic engineering CRISPR/ Cas9 is a new path way to use for genome editing enhancement in Indian mustard crop. This transgenic technology is mainly used for crop improvement in Indian mustard and need to identified target gene to gene editing for improve edible oilseed crop.
