ABSTRACT The genetic diversity, existing among the indigenous germplasm of jackfruit (Artocarpus heterophyllus Lam.) of northern Tripura state, was observed on the light Multiple Correspondence Analysis (MCA), depending on 24 (twenty-four) numbers qualitative attributes. It revealed that the Qualitative traits of jack fruit like fruit bearing habit, alternate bearing, leaf blade shape, fruit clustering habit, inflorescence colour and pulp colour have expressed relatively large values on both dimension 1 and dimension 2 of the discrimination measures plot. Whereas, the Object score plot specially helped to spot outlier accessions such as JF-24, JF-48, JF-1, JF-32, JF-45, JF-21, JF-35, JF-26, JF-19, JF-12, JF-3 etc. Category quantification plots identified irregular fruit shape, elliptical crown shape, acidic pulp taste and flat shape of spine act as large discriminants along Dimension 1, along with bitter and sweet pulp taste, weak pulp flavour, fruit bearing on primary branches and pyramidal crown shape with Dimension 2. |
