“…As the findings are in desirable direction and indicated certain inherent relationship between plant height, leaf length, dry recovery percentage and rhizome yield these traits may be further studied or utilized in future turmeric crop improvement program. Similar findings were also reported by Luiram et al (2019), Dhanalakshmi et al (2021) and Poonam et al (2022) in turmeric. On the other hand, both leaf blotch incidence (PDI) (-0.420) and leaf spot incidence (PDI) (-0.716**) showed negative correlation with the rhizome yield per plot.…”

“…Hence, it indicated the predominance of additive gene action ample scope for improving these traits would be effective for the direct selection. The findings are in accordance with the results of turmeric (Mishra et al, 2015) and (Luiram et al, 2018).…”

Background: Canna lily (Canna indica L.) is an edible herbaceous perennial plant in which flowers and rhizomes were commonly used as a food additive and its potentiality was not fully utilized in India. To stun these hindrances, morphological characterizations are needed to determine the genetic variability to improve flower quality and rhizome yield in canna lily. Methods: In the present research, a field experiment was conducted during 2022-2023 in Botanical Garden, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu. Twelve accessions were investigated by using a randomized block design with 3 replications. All the observations for 23 quantitative traits were carried out at 0.05 and 0.01 probability. Results: The wide range of genetic variability was observed, a high genetic coefficient of variation ranged from 8.49 to 75.62 % and a phenotypic coefficient of variation ranged from 8.83 to 76.50 % was observed in 20 traits except in time taken for first flowering, rhizome diameter, number of nodes per rhizome. High heritability coupled with high genetic advance as a percent of mean was observed for 21 traits except in time taken for flowering and number of nodes per rhizome. Character association analysis revealed that stem diameter and inflorescence length showed highly significant and positively correlated with flower yield and rhizome yield per plant. Path analysis specified that the number of leaves per clump had a very high and positive direct effect on fresh flower yield per plant.

“…curing percentage was in the genotype PTS-38 (28.5). Mohan et al (2017) noticed that, curing percentage was higher with IISR Alleppey Supreme (22.3 %) and Luiram et al (2018) found highest curing percentage in the genotype TPR-2 (24.50%). The variation in curing percentage was mainly depends on moisture content of rhizomes.…”

Collection, evaluation and characterization of turmeric (Curcuma longa L.) genotypes prevailed in Southern Karnataka was carried out during 2018-19 and 2019-20 of Kharif season. Over 66 turmeric genotypes were studied to elucidate morphometric and genetic diversity. A significant difference among the genotypes for growth, yield and quality traits was recorded for all the traits was observed. Result from the pooled data, the maximum number mother rhizomes, primary fingers and secondary finger was found with genotype 13.65, and 18.96). Along with the highest fresh weight of mother rhizome, primary and secondary finger was also recorded with 302.72 and 210.23 g). Genotype TC-36 registered maximum girth and length of mother rhizomes, primary and secondary finger (14.19, 8.49 and 6.18 cm; 9.99, 9.23 and 7.56 cm). The maximum fresh rhizome yield (49.27 t ha -1 ), curing percentage (25.77) and cured yield (12.70 t ha -1 ) was also registered with TC-36. Overall from this evaluation data the genotypes viz., TC-36, TC-61, TC-60-2, TC-60, TC-51, TC-27, TC-33, TC-37, TC-19 and TC-21 contributing towards yield and perform well in southern region of Karnataka. These genotypes need to be studied in larger field trials for their stability to growth, yield and quality and also in multilocation trail.
