Multiplication and evaluation of promising jackfruit genotypes

The results of the study conducted on Multiplication and Evaluation of Identified Elite Jackfruit (Artocarpus heterophyllus Lam.)" genotypes from 2020-2022. The genotypes viz., KDM-Ah-8, KDM-Ah-10, and KDM-Ah- 46 were grafted through softwood and inarch grafting. The success percentage varied from softwood grafting to approach grafting. Among the grafting techniques, softwood grafting recorded the highest success of 40 percent in the genotype KDM-AhJ-08. Meanwhile, 90 percent success was recorded in the genotype KDM-AhJ-08 under approach grafting. Three identified elite jackfruit genotypes, KDM-AhJ-08, KDM-AhJ-10, and KDM-AhJ-46, were planted along with check varieties viz., PLR1, PLR2, red-fleshed jackfruit Siddu and Shankara. The highest tree height of 2.40 m was recorded in the genotype KDM -AhJ-8, and the lowest plant height of 1.70 m was recorded in the genotype Shankara red flesh. The highest stem girth of 32 cm was recorded in the genotype KDM-AhJ-08, and the lowest stem girth of 20.00 cm was recorded in the genotype Shankara red flesh. The highest plant circumference of 3.00 m was recorded in the genotype KDM-AhJ-08, and the least of (1.00 m) was recorded in the genotype Shankara red flesh. The highest number of primary branches of 6 was obtained in the genotype KDM-AhJ-08, and the lowest was obtained from the Siddu red flesh (3 Nos.). The highest number of secondary branches, 16, was recorded in the genotype KDM-AhJ-08, and the lowest number of 6 was obtained from the genotype Siddu red flesh. The genotype Shankara red flesh recorded the highest leaf length of 19 cm, and the lowest leaf length of 14 cm was recorded in the genotype KDM-AhJ-08. The highest leaf breadth of 10.10 cm was obtained from the varieties PLR1 and Shankara red flesh, and the lowest of 7.60 cm was recorded in the genotype Siddu red flesh.
