Variability, heritability and genetic advance for yield and yield contributing characters in Oroxylum indicum (L.) Vent: A threatened medicinal tree

Not AvailableAbstract The experiment was conducted during 2016-2017 at Division of Plant Genetic Resources, ICAR-Indian Institute of Horticultural Research (ICAR-IIHR), Hessarghatta, Bengaluru. Genotypic variability, heritability and genetic advance for yield and yield contributing traits were studied in ten Oroxylum indicum (L.) Vent. accessions. Data were recorded for plant height (m), stem girth (cm), leaf length (cm), leaf width (cm), petiole length (cm), leaf area (cm2), number of pods per tree, pod length (cm), width of pod (cm), number of seeds per pod, pod yield (kg/plant). Among different yield attributing characters studied, the highest magnitude of PCV and GCV were recorded in leaf area (26.869 and 27.827 %), number of pods per plant(36.593 and 37.610 %) and pod yield per plant (46.319 and 46.912 %).High heritability coupled with high genetic advance as per cent over mean was recorded for the characters viz., leaf length (90.30 %), petiole length (85.20%), leaf area (93.20 %), number of pods per tree (94.70 %) and pod yield per plant (97.50 %).Hence, these characters were predominantly governed by additive gene action and could be used as a selection criterion for breeding programmes in the future.

Not AvailableThirteen accessions of Salacia chinensis L., a threatened species known for its medicinal properties, were evaluated in terms of variability, heritability and genetic advance for yield and other contributing traits. Genotypic and phenotypic coefficient of variation were highest for fruit yield per plant followed by plant spread, fruit weight and seed weight. High heritability were observed for fruit weight (99.1 %), fruit yield per plant (98.5 %), seed length (98.1 %), seed weight (97.2 %), leaf area (96.8 %), fruit length (96.8 %), plant spread (96.2 %), seed diameter (96.2 %), fruit diameter (94.2 %), leaf length (92.1 %), leaf width (86.4 %), plant height (85.1 %) and petiole length (84.1 %) thus indicating that these characters has additive gene effect and hence, they can be used for effective selection.Not Availabl

Not AvailableAbstact Oroxylum indicum (L.) Vent. is an important threatened medicinal tree. An experiment was undertaken to study the correlation and path analysis in Oroxylum indicum (L.) Vent. accessions during 2016-17. Correlation study revealed that number of pods per plant, leaf area, leaf width and petiole length had significant positive correlation with pod yield per plant. According to path analysis, number of pods per plant, leaf length, plant height, pod width, number of seeds per pod and number of pods per plant recorded positive and high direct effect on pod yield per plant. Thus, based on correlation and path analysis, traits viz. number of pods per plant and pod length can be considered as selection indices for high pod yield in this species.Not Availabl

Not AvailableAbstract Six accessions of Decalepis hamiltonii Wight & Arn., a threatened species known for its medicinal properties, were evaluated for variability, heritability and genetic advance in respect to yield and its contributing traits. Genotypic coefficient of variation and phenotypic coefficient of variation were highest for pedicel length followed by fruit length and petiole length. High heritability and high genetic advance over mean were observed for petiole length (93.13%), fruit length (87.43%), fruit yield (80.63%) and leaf length (72.44%) thus indicating that these characters had additive gene effect and hence, they can be used for selection of superior genotypes.Not Availabl

Not AvailableAbstract An experiment was undertaken to study the correlation and path analysis in thirteen accessions of Salacia chinensis L. Correlation study revealed that plant height, plant spread, fruit diameter, fruit weight, seed diameter, seed length and seed weight had positive significant correlation with fruit yield per plant at both genotypic and phenotypic levels. According to path analysis the seed length, plant height and seed diameter recorded positive and high direct effects on fruit yield per plant while, seed weight, fruit length and leaf length had high negative direct effects on fruit yield per plant. Thus based on correlation and path analysis, the traits viz., plant height, plant spread, fruit diameter, fruit weight, seed diameter, seed length and seed weight can be considered as selection indices for high yieldNot Availabl

Variability, heritability and genetic advance for yield and yield contributing characters in Embelia ribes Burm f. – An endangered medicinal plant

Not AvailableAbstract The experiment was conducted during 2015-2016 at Division of Plant Genetic Resources, ICAR-Indian Institute of Horticultural Research (ICAR-IIHR), Hessarghatta, Bengaluru. Genotypic variability, heritability and genetic advance for yield and yield contributing traits were studied in five Embelia ribes Burm f. accessions. Data were recorded for plant height (m), leaf length (cm), leaf width (cm), petiole length (cm), leaf area (cm2), number of inflorescence per plant, fruit length (cm), fruit diameter(cm), seed length(cm), seed weight, fruit yield (kg/plant). Among different yield attributing characters studied, the highest magnitude of PCV and GCV were recorded in leaf area (6.43 and 5.73 %), number of inflorescence per plant (46.35 and 45.10 %) and fruit yield per plant (48.67 and 48.24 %). High heritability coupled with high genetic advance as per cent over mean was recorded for the characters viz., leaf width (99.00 %), petiole length (91.00%), plant height (95.20 %), number of inflorescence per plant (95.00 %), fruit weight (91.02) and fruit yield per plant (98.22 %).Hence, these characters were predominantly governed by additive gene action and could be used as a selection criterion for breeding programmes in the future.

Not AvailableCelastrus paniculatus Willd. is an important Ayurvedic medicinal plant gaining popularity in the primary healthcare systems and in herbal drug formulations. Its seed oil is reported to be beneficial in stimulating intellect and sharpening memory. This work has been undertaken to study the effect of different growth regulators on seed germination of this endangered medicinal plant species, Celastrus paniculatus Willd.. Various growth parameters were recorded for seed germination and significantly higher results for Rate of germination (0. 78), Plant vigour (2082. 74), Plant height (22. 10cm), number of leaves (7. 83) fresh weight (136. 58 mg) and Dry weight of plant (59. 16 mg) was noticed in seeds treated with GA3 400ppm.Not Availabl

In-vitro conservation studies in Salacia chinensis L. a threatened medicinal plant

Not AvailableAbstract Salacia chinensis L. a high valuable anti-diabetic medicinal plant of Hippocrateaceae family, possess various medicinal properties. Due to the lack of proper cultivation practices, excessive and indiscriminate collection of plant for supplement of global demands on herbal medicine, S. chinensis L. is severely threatened in nature. Micropropagation system was developed for commercialization and in-vitro conservation. Nodal segments were cultured on MS media supplemented with different growth regulators like BAP, NAA, IAA and KIN among these treatments, combination of BAP (2 mg/l) and NAA (0.8 mg/l) shows higher shoot length (3.40±0.12 cm), number of shoots (3.27±0.07) and number of leaves per explant (7.00±0.17) were observed. The same combination of BAP (2 mg/l) and NAA (0.8 mg/l) shows highest survival per cent, high shoot length, number of shoots per explant and number of leaves under in-vitro conservation for six month of period. These efforts could help to propagate plants with high medicinal value and thereby, meeting the demands of the growing population by sustainable use and conservation.

Character Association for Seed yield and Yield traits in Celastrus paniculatus Willd

Not AvailableThis experiment was undertaken to study the correlation and path analysis in six accessions of Celastrus paniculatus Willd. Correlation study revealed that the various parameters such as plant height, leaf length, leaf width, petiole length, leaf area, fruit diameter and seed length had high significant positive correlation with seed yield per plant. According to path analysis, leaf length, leaf width, petiole length, fruit diameter and seed length had high positive direct effects on yield per plant. Plant height, leaf area and fruit length had negative direct effects on yield. Thus based on correlation and path analysis, the traits viz., plant height, leaf length, leaf width, petiole length, leaf area, fruit diameter and seed length may be considered as selection indices for high yield.Not Availabl
