| Abstract | Curry leaf (Murraya koenigii L.) is an important perennial herbal spice widely used for culinary purpose in India for centuries and the leaves valued for its characteristics flavour and aroma. Leaves possess medicinal and neutraceutical properties due to the presence of vitamins, minerals and phytochemicals. In Kerala, cultivation is limited to landraces which are often reported to be low in quality. Identification of promising types with high yield and quality will pave way for promoting large scale cultivation in Kerala. The present study entitled “Evaluation of curry leaf (Murraya koenigii L.) accessions for yield and quality” was undertaken with objectives of morphological and biochemical characterization of available accessions and standardization of vegetative propagation. accessions of curry leaf maintained by the Department of Vegetable Science, College of Horticulture, Vellanikkara along with the released variety Suvasini were used as the experimental material. Among the accessions, wide variability was recorded for fifteen quantitative and five qualitative morphological characters studied. Cluster analysis was performed and superior accessions were selected and those were subjected to biochemical analysis. Among the accessions, 76 % were having green midrib and petiole whereas 24 % with light red pink. Leaf colour was found as dark green in 19 % of accessions and the remaining accessions were green in colour. Only two leaflet shape were noticed with 19 % having lanceolate shape. The plant height varied from 2.23 m (MK 107) to 5.21m (MK 103) whereas branching height ranged from 31.25 cm (MK 125) to 67.51 cm (MK 122). Accession MK 118 recorded highest canopy spread in N-S direction (4.57 m) while MK 142 recorded in E-W direction (4.78 m). Considerable variability was observed in number of primary, secondary and tertiary branches and more than 40 numbers of tertiary branches were recorded in five accessions namely MK 107, MK 118, MK 126, MK 142 and MK 160. The leaf length ranged from 14.71 cm (MK 122) to 21.81 cm (MK 126) whereas maximum number of leaflets (22 leaflets) were observed in three accessions viz., MK 126, MK 142 and Suvasini with the largest leaf area of 66.46 cm2 in MK 142. Curry leaf was harvested at four months interval from June to March. Harvesting during June- July months in the rainy season recorded the highest leaf yield per plant. Leaf yield of more than 5 kg per plant was obtained in four accessions namely, MK 107, MK 126, MK 142 and MK 160. Aroma and flavour are the important parameters in curry leaf and based on sensory evaluation, eight accessions were identified as superior with a mean sensory score of above 7, with the highest score of 7.40 and 7.33 for flavour and aroma in MK 126. Correlation analysis revealed significant and positive correlation of yield with number of primary, secondary and tertiary branches, canopy spread in N-S and E-W direction, number of leaflets, and leaf area. Based on cluster analysis, all the thirty accessions under the study were grouped into twelve clusters and ten accessions from superior clusters were selected for biochemical analysis. Oil recovery was higher in dry leaves than in fresh whereas antioxidant activity and beta carotene content were higher in fresh leaves. Highest essential oil recovery was recorded in dried samples of accession MK 186 (1.09 %) and maximum content of crude fibre was recorded in two accessions namely MK 118 (11.61 %) and MK 186 (11.65 %). Accession MK 126 recorded the highest content of carbohydrate (15.99 %) and protein (6.00 %). Highest content of total phenol (0.31 %) and antioxidant capacity (3.45) was recorded in MK 105. The beta carotene content was found higher (˃ 8.80 mg 100g-1) in three accessions namely, MK 105, MK 142 and MK 186. Considering yield and quality MK 142 and MK 126 were identified as most promising types followed by MK 105 and MK 186. Standardization of vegetative propagation was done in Suvasini with softwood, semihardwood and hardwood types of cuttings, two growth regulators (IBA and NAA) at different concentrations of 1000ppm, 2000ppm and their combinations during rainy, winter and summer season. Even though success rate of vegetative propagation through stem cuttings was very low, hardwood cuttings treated with highest concentration of growth regulator (2000ppm IBA+2000ppm NAA) resulted in 3.3 % of establishment during rainy season. |
