“…FL, SW, SPW, TP, NRS, PR, Ca, P and K) showed a higher influence than the others on the grouping of landraces on the phenotypic-based-dendrogram. These findings are supported by previous results of Wangchu et al (2013) who reported that most of the abovementioned traits are recommended as selection criteria for development of effective and productive plant types in jackfruit. Morphological and chemical data of the present study were used to perform the cluster analysis based on Euclidian dissimilarity coefficient.…”

Assessment of genetic diversity and relationship among six landraces of jackfruit (Artocarpus heterophyllus) grown in Aswan Botanical Garden (Aswan, Egypt) was preformed using morphological, chemical and molecular evaluations. A wide range of variability was observed among the tested landraces, reflected by highly significant differences in all evaluated traits. Among which, fruit length, seed weight, fruit peel weight, total phenolics, non-reducing sugars, protein, calcium, phosphorus and potassium content showed higher influence than others, the way that affected the relationship among landraces and their grouping in dendrogram. These traits are highly recommended to be included in successive evaluation studies of jackfruit. Cluster analysis based on the phenotypic data allowed the grouping of the landraces according to their shared features of higher or lower values of morphological and chemical traits, which could be helpful in the subsequent crop improvement efforts. On the other hand, molecular analysis using inter simple sequence repeats (ISSR) markers clearly confirmed the degree of variability among jackfruit landraces by showing a high percentage of polymorphism (up to 71.43%) and providing a good cluster relationship in the ISSRbased-dendrogram. Furthermore, combining phenotypic and molecular data to perform cluster analysis, gave an insight into the landraces' relationships. High similarity was observed between molecular-and combined-based dendrograms unlike phenotypic-based one. Results herein can benefit the breeding programs of jackfruit.

“…These findings will help in selecting superior genotypes. This is in accordance with some of the findings of Wangchu et al [29] who recorded direct effect of fruit length, fruit weight, flake length and number of seed per kg of fruit on fruit yield.…”

“…The path coefficient analysis at phenotypic level revealed that weight of fresh flake without seed (21.1008) has maximum positive direct effect on fruit yield per tree followed by 100-seed weight (5.6297), number of seeds per kg of fruit (1.7891), weight of flakes per kg of fruit (0.6414), rachis length (0.5074), fruit diameter (0.3871), flake length (0.3136), reducing sugar (0.2413), leaf blade width (0.1527), total carbohydrate content of seed (0.1512), rachis diameter (0.1393), protein content of seed (0.1220), TSS (0.0992), fruit weight (0.0835), seed width (0.0769), petiole length (0.0753), stalk length (0.0700) and seed length (0.0345) ( Table 6). In accordance with present investigation, Wangchu et al [29] also observed positive direct effect of stalk length, fruit weight, weight of flakes per kg of fruit, flake length and 100-seed weight on fruit yield per tree. Further, the negative direct effect of weight of flake with seed, flake/fruit ratio, number of flakes per kg of fruit, fruit length, leaf blade length, stalk diameter, fruit rind weight, total sugar and flake width was observed on fruit yield per tree.…”

“…Fruit weight was significantly positively correlated with fruit diameter followed by fruit length and fruit rind weight. Similar results was obtained by Wangchu et al [29] who observed high significant positive association of rind weight, rachis length, fruit length and flake length with fruit weight. The genotypic correlation coefficients of different characters showed that fruit yield per tree had significant and positive correlation with fruit diameter (0.556), rachis diameter (0.523), fruit weight (0.466), petiole length (0.430), fruit length (0.389), flake length (0.381), leaf blade width (0.359), rachis length (0.358), seed length (0.326), reducing sugar (0.318), fruit rind weight (0.310), total sugar (0.299), 100-seed weight (0.287), stalk length (0.284), leaf blade length (0.208) and weight of flakes per kg of fruit (0.202) ( Table 5).…”

The present investigations were carried out on forty genotypes of jackfruit (Artocarpus heterophyllus Lam.) to determine the extent of variability present in the material and association among different traits. The genotypes were collected from six north-eastern states of India viz. Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram and Tripura during the two years 2016 and 2017. Selection and identification of superior genotypes were done following IPGRI jackfruit descriptor. The experiment was laid using randomized block design with three replications during the year 2016 and 2017 under Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, East Siang, Arunachal Pradesh. The phenotypic coefficients of variability and genotypic coefficients of variability were recorded highest values for weight of fresh flake without seed (52.69% & 50.52%, respectively), stalk length (51.09% & 49.06%, respectively) and fruit weight (48.11% & 45.86%, respectively). High heritability coupled with high genetic gain was observed for stalk length, fruit weight, weight of fresh flake with seed and weight of fresh flake without seed traits. Genetic advance was recorded highest for 100-seed weight followed by stalk length and lowest for flake/fruit ratio followed by seed width traits. Yield per plant showed significant and positive genotypic correlation coefficient with fruit diameter, rachis diameter, fruit weight, petiole length, fruit length and flake length traits. The path coefficient analysis revealed that weight of fresh flake with seed has maximum positive direct effect on fruit yield per tree followed by weight of flakes per kg of fruit.

“…The accessions, Ashoka Yellow, Janagere, Byrachandra and Ashoka Red were selected for the above characteristics as most of these accessions were better for fruit and flake characteristics than the check variety (NSP) used in the present study. Similar reports on fruit quality traits have been made by several scientists in jackfruit Azad and Haq (1998); Singh and Srivastava (2000) and Wangchu et al, (2013).…”

The study involved characterization of Jackfruit accessions with obloid (round) versus ellipsoid fruit shape. The morphological characterization was based on tree, fruit and seed descriptors. The Jackfruit accessions exhibited wide range of differences. The dominant tree growth habit was erect type, with medium to low branching density and branching pattern was irregular in most of the trees. With respect to fruit rind weight, it was more than fifty to sixty per cent in accessions with obloid fruit, than ellipsoid fruits. The rind weight ranged from thirty to forty per cent of the total fruit weight. Based on fruit and flake quality characters, the accessions such as Allilugatta 5, Kumaraswamy, Manipur Parmesh and Swarna in obloid fruits and Ashoka Red, Ashoka Yellow, Byrachandra, Janagere and NSP in ellipsoid fruits have been identified for commercial purpose. Among ten RAPD primers screened, two primers showed higher PIC value (0.24) viz., OPA 4 and OPAH 4. Similarly among ten ISSR markers screened, ISSR - 868 (0.31) showed higher PIC value. These can be used effectively to probe the genetic variations among the Jackfruit accessions.
