Thus, an intraspecific F<sub>1</sub> hybrid was raised involving two contrasting genotypes of <em>C. ternatea acc. CtB3-SL1</em> (Blue flowered) and <em>C. ternatea acc. CtW2-BL1</em> (white flowered). The hybridity of the F<sub>1</sub> plant was confirmed by assessing the phenotypic traits, such as colour of the petal, pod shape and seed coat colour, 100 seed weight, and the content of taraxerol and delphinidin. The pollen mother cells in the F<sub>1 </sub>hybrid showed eight bivalents with preponderance of ring bivalents and 8I:8I segregation at metaphase-I and Anaphase-I, respectively. SDS-PAGE seed albumin and globulin detected three pollen parent-specific polypeptides (Mw 31.62, 22.38 and 18.81KDa), and were inherited to F<sub>1</sub> hybrids, which evidenced the hybridity of putative F<sub>1</sub> plants. Further, DNA marker analysis also showed the inheritance of 11 RAPD, six SCoT and one ISSR markers to putative F<sub>1</sub> plant, which affirmed the hybrid nature of the F<sub>1</sub> plant. This study also evidenced that combined use of morphophysiological, cytogenetic, protein and DNA marker analyses could be effective for precise characterization of intra-specific hybrids in <em>C. ternatea.</em> These F<sub>1</sub> hybrid and its derived future progenies could also be used for mapping of QTLs or genes contributing higher accumulation of taraxerol and delphinidin in different plant parts.</p>}, number={3}, journal={Caryologia}, author={Naik, Aparupa and Patel, Amiya K. and Mishra, Sujit K. and Nag, Atul and Panigrahi, Jogeswar}, year={2019}, month={Dec.}, pages={11–22} }
