| dc.description.abstract | The study entitled “Survey, evaluation, collection and multiplication of red jackfruit (ArtocarpusheterophyllusLam.) types grown under Southern districts of Karnataka” was conducted during 2018-19. The survey was done in five districts and selected 23 red type jack trees for characterization. Among them, six were old age (> 40 years), 13 of medium age (20-40 years) and four were young age (< 20 years) with varied canopy shape. The canopy spread was maximum (NS -17.5 m, EW - 18.00 m) in ABS - 1 and minimum (NS - 2.3 m and EW - 2.5 m) in MYC-1. HSK-17 recorded maximum fruit length of 36.00 cm and width of 26.00 cm. The genotype ABS-1 recorded highest number of fruits per tree (90), highest yield (1080 kg per tree), highest fruit weight (12.00 Kg), fake mass (5.36 kg), flake per cent (44.63 %), maximum bulb weight (45.25 g), bulb mass (5.68 kg) and lower seed weight (2.58 g). The highest number of bulbs were observed in HGN-1 (188). The maximum bulb length and width was recorded in HSK-17, BHB-1 and BKH-3 (8.10 cm and 5.43 cm, respectively). The maximum instrumental colour value (a*) red (23.4), total carotenoids (3.45 mg /100g) and antioxidants (15.72 mg AAE 100-1g) were recorded in MDS-1. The highest moisture content (78.75 %), titrable acidity (0.47 %) and sugar acid ratio (97.40) was observed in MAK-1, KTC-4 and MHK-1, respectively.Significantly higher TSS (35.00 °B), total sugar (31.73 %) and reducing sugar (16.78 %) was recorded in the genotype HGN-1. Softwood grafting of elite 15 genotypes on six month old rootstocks showed graft success of 40.67 % (ABS-1) at 90 days after grafting and survivability percentage of 71.67 % (ABS-1) at 120 days after grafting. Other parameters such as number of leaves, sprouts, height and girth recorded significant difference. | en_US |
