    (College of Horticulture, Mudigere, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Shivamogga, 2021-11-10) SAHANA, P. V.; Dr. YALLESH KUMAR H. S.; Dr. SHIVAKUMAR, B. S.
    A field experiment was conducted to study the influence of bunch cover on yield and quality of banana cv Ney Poovan (AB) under high density planting system in hill zone of Karnataka during 2020-21 at famer's field, Kittlegandi village, Mudigere taluk. Experiment was laid out in Randomized Complete Block Design comprising of eight treatments with three replications. Among the different treatments studied, the treatment blue non-woven polypropylene bunch cover (17 GSM 100% UV stabilized) recorded maximum bunch weight (11.05 kg), bunch width (35.01 cm), bunch length (60.13 cm), number of hands per bunch (11.58), number of fingers per bunch (162.14), finger weight (69.12 g), finger girth (37.68 mm), finger length (12.28 cm), hand weight (1.11 kg), number of fingers in second hand (15.48) and yield per hectare (36.82 t). The same treatment recorded minimum number of days taken from shooting to harvest (115.94). Behavioural parameters such as maximum green life (5.10 days), shelf life (9.20 days), minimum physiological loss in weight (8.20 %). Fruit quality parameters viz., TSS (27.37 °B), total sugars (20.50%), reducing sugars (17.17%) and non-reducing sugars (3.33%) were recorded maximum in bunch covered with blue non-woven polypropylene (17 GSM 100 % UV stabilized) bag. There were no incidence of thrips and anthracnose observed and also maximum B:C ratio (2.43 :1) was obtained in the same treatment. Hence, the treatment blue non-woven polypropylene bunch cover (17 GSM 100% UV stabilized) proved to increase yield, quality and reduce the incidence of pests and diseases in banana cv. Ney Poovan under high density planting system. Further, the treatment white non-woven polypropylene bunch cover (17 GSM 100% UV stabilized) also recorded on par results with the above treatment with respect to yield, quality and in reducing the pest and diseases in banana.

    EXPLORATION AND IDENTIFICATION OF ELITE ACCESSIONS OF KOKUM (Garcinia indica (Thouars) Choisy) IN UDUPI DISTRICT OF COASTAL KARNATAKA
    (College of Horticulture, Mudigere, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Shivamogga, 2023-12-18) PRAVEENKUMAR, B; Dr. CHAITANYA, H. S.; Dr. SHIVAKUMAR, B. S.
    The exploration study of elite accessions of Kokum was carried out at coastal zone taluks of Udupi district (Bramhavara, Hebri and Kundapura), during Rabi and the summer season 2020-21. The morphological characterization of 17 accessions showed a wide variation for tree, leaf, flower, fruit and seed characteristics. Analysis of variance revealed significant differences among the 17 accessions for yield and quality attributes. Significantly higher fruit weight (70.63 g), fruit length (6.73 cm), fruit diameter (5.90 cm), fresh weight of rind (29.25 g) and dry weight of rind (5.21 g) was recorded in Acc. 15. While the Acc. 12 recorded significantly higher hydroxy citric acid (22.25 %) and anthocyanin (2.41 mg/100 g). The higher GCV and PCV coupled with higher heritability and genetic advance were observed for most of the economic traits indicating that these characters are highly heritable and likely to provide high selection response. Correlation studies revealed that the fruit yield per tree had a positive and highly significant correlation with the number of harvests, fresh weight of rind and dry weight of rind at both genotypic and phenotypic levels. Genotypic path co-efficient analysis for yield per tree indicated that the dry weight of rind (1.033) had the highest positive direct effect followed by the number of harvests (0.802). While, total hydroxy citric acid, the fresh weight of rind (0.717), followed by anthocyanin (0.284) and the fruit length (0.277) had a high positive direct effect. The genetic diversity among the accessions was maximum which resulted in the formation of six clusters. Among different grafting techniques, softwood grafting with Garcinia cambogia as rootstock shows a maximum survival percentage.

    An experiment was conducted on "Evaluation and characterization of Garcinia biotypes in Chikkamagaluru District" during 2020-21. The research was implemented using factorial completely randomized design with two factors (species and locations) and four replications. The morphological and biochemical parameters of fruits were studied in explored three species of Garcinia viz., Garcinia gummigutta (S1), Garcinia indica (S2) and Garcinia xanthochymus (S3) from five locations of Chikkamagaluru district viz., Mudigere (L1), Narasimha Raja Pura (L2), Sringeri (L3), Koppa (L4) and Chikkamagaluru (Ls). It was found that, with respect to morphological characteristics viz., fruit length (6.46 cm), fruit diameter (7.16 cm), fruit weight (180.50 g), fruit volume (200 cc), rind weight (121.70 g) and seeds weight per fruit (25.10 g) were recorded maximum in Garcinia xanthochymus from Sringeri (L3S3), compared to G. indica from Koppa (L4S2). With respect to the nutritional and phytochemical compositions viz., crude fibre (14.50 %), ascorbic acid (37.45 mg/100g), potassium (46.50 mg/ 100g), calcium (14.00 mg/100g), anthocyanins (2.40 mg/100g), polyphenols (45.40 mg GAE/100g) and tannins (1.70 %) were recorded highest in Garcinia indica from Sringeri (L3S2), than the Garcinia gummigutta from Koppa (L4S1). However, the antioxidant activity was maximum (41.62 μg/ml) in Garcinia indica from Koppa (L4S2), which was on par with (40.45 μg/ml) Garcinia indica from Sringeri (L3S2). Whereas, the potential antiobesity component, Hydroxycitric acid (HCA) was recorded maximum (9.72 %) in Garcinia gummigutta from Sringeri (L3S1) than the Garcinia xanthochymus (0.14 %) from Koppa (L4S3). Hence, the study shows Garcinia xanthochymus from Sringeri (L3S3) highly significant for morphological parameters. However, Garcinia indica from Sringeri shows the maximum significant values for the nutrients and phytochemical compositions. The Garcinia gummigutta species from Sringeri shows the maximum significant values for the Hydroxycitric acid than Garcinia xanthochymus.

    (College of Horticulture, Mudigere, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Shivamogga, 2021-12-03) BHAGYASHREE DUNDAPPA HOSUR; Dr. NAGARAJAPPA ADIVAPPAR; Dr. GANAPATHI. M
    An experiment was conducted on evaluation of aonla genotypes for yield and quality traits in Southern Transition Zone, during 2020-21 at Forest Research Station, Govinakovi, Honnali taluk, Davangere district in Karnataka. The experiment was laid out in randomized complete block design with three replications involving 14 vegetatively propagated genotypes (18 years old). The genotypes showed significant variation in terms of fruit, yield and biochemical parameters. With respect to fruit parameters the maximum fruit weight (50.84 g), fruit length (4.15 cm), fruit diameter (4.55 cm), fruit volume (47.33 cc), pulp weight (48.43 g), pulp to seed ratio (20.09) and yield (54.11 kg/plant) was recorded in genotype NA-7. With respect to biochemical parameters the maximum acidity content (2.39 %), vitamin C (403.65 mg/100g), phenol (1.62 %), flavonoid (1.73 mg QE/g) and antioxidant (92.18%) recorded in K-23 genotype. In general, phenotypic coefficients of variation (PCV) were higher in magnitude than genotypic coefficients of variation (GCV) and narrow difference between them indicates the less environmental influence on expression of trait. High heritability coupled with high genetic advance was observed for all the characters except number of seeds per fruit, phenol and antioxidant. Correlation studies revealed that, yield per tree showed highly significant and positive association with fruit weight, volume, length, diameter and pulp weight at both phenotypic and genotypic levels. Whereas, biochemical parameters showedsignificant and positive association with yield at genotypic level only. Path analysis for yield per tree showed direct and positive association with fruit diameter, pulp weight, acidity, total sugar and reducing sugar. Among the characters studied, tannin content contributed maximum (18.68 %) to the genetic diversity, followed by vitamin C (17.58%). Among 14 aonla genotypes, NA-7 is promising genotype for yield parameters followed by NA-6. Whereas, K-23 is superior for quality parameters in Southern Transition Zone of Karnataka.
