“….1). Similar research in mulberry also recorded Sushmitha et al, [9] where in the leaf yield parameters exhibited higher phenotypic coefficient of variance than genotypic coefficients of variance which corroborate the findings of current study. A plethora of workers have also reported similar higher values for PCV than GCV particularly in species like Neolamarckia cadamba [10]; Jatropha curcus [11] and Leucaena leucocephala [12] are lend support to the reports of current investigation.…”

Aims: This study aims to evaluate the wood quality and leaf quality traits of selected mulberry clones and assess the genetic divergence among them, providing valuable insights for the development of superior genotypes with enhanced economic value for the sericulture and agroforestry sectors. Study design: Twenty-one genetic resources of mulberry were collected from various regions in India and evaluated through clonal test in a Row Column Design to assess growth attributes and genetic divergence. Place and Duration of Study: The study was conducted in India, and the systematic progeny test and clonal evaluation were carried out in Forest College and Research Institute, Mettupalayam during 2018-2022. Methodology: The selected clones were evaluated for growth attributes such as plant height, diameter at breast height (DBH), volume, number of branches, leaf length, leaf width, petiole length, number of leaves, and leaf area. Genetic divergence was estimated using D2 statistics, and clustering of clones was performed using the 'GENRES' statistical package. Results: The study identified several clones with significantly higher growth attributes, highlighting their potential for selection in breeding and cultivation programs. Variability and heritability studies indicated that volume exhibited the highest heritability, suggesting strong genetic control and potential for improvement. Conclusion: Clones MI-0718, MI-0807, and MI-0845 showed superior growth performance and genetic divergence, indicating their suitability for further breeding and improvement programs. The study provides insights into the genetic variability of mulberry clones and emphasizes selecting superior clones for enhancing wood volume and overall productivity.

“…Present study is in accordance with [14] who reported that non-additive genetic variance is more often evident in controlling the inheritance of majority of yield traits than additive components in mulberry [15] reported that predominance of non-additive genetic variance offers scope for exploitation of heterosis in mulberry.…”

The study was conducted to evaluate combining ability for growth, quality and yield parameters in mulberry at the field germplasm existed at the Department of Sericulture, UAS, GKVK, Bangalore. Twenty one F1 hybrids was developed by crossing seven lines with three testers according to line x tester design. and assessed using randomized complete block design with three replications. Results revealed that analysis of general combining ability showed the higher magnitude of specific combining ability (SCA) variance than general combining ability (GCA) variance for most of the characters, which indicates the presence of non- additive gene action for most of the traits except for number of branches per plant, number of leaves per plant, and single leaf area. Among seven lines, M. cathyana, MI-47, M. laevigata, MI-494 were found to be best general combiners and in testers V1, MI-66 were found best general combiners with high GCA effects. Among twenty one crosses, BC-259 × MI-66, M. indica × MI-66, M. laevigata × V1 and M. indica × C-776 were found to be superior performers with high SCA effects.

“…Similar findings were reported by Ghosh et al (2009), who indicated that wider spacing plantation systems had considerably better contributing traits and leaf yield than narrow-spacing plantation systems.…”

“…The lower number of leaves per shoot was observed in 5ftx 5ft (49.40) of G4. According to Ghosh et al (2009), mulberry leaf yield and growth metrics were both higher with wider spacing than with close spacing. In accordance with Yadav et al (2019) study, 270 cm x 60 cm spacing produced the highest plant height (194.56 cm), number of branches per plant (13.59), number of leaves per plant (286.27), and leaf yield per plant (1.35 kg), followed by 240 cm x 60 cm spacing.…”

The two tree type, mulberry V1 and G4, were examined in the investigations for the impact of various spacing on growth and yield metrics. The results show that spacing has an impact on how mulberries grow. Among the different spacings, 6 ft x 6 ft had the highest single shoot length (133.10 cm), minimum internodal length (3.95 cm), length of the longest shoot (128.47 cm), total shoot length (1267.18 cm), physiological attribute like leaf area (137.75 cm2), and yield attributes like single leaf weight of 5.35 g, weight of 100 leaves (518.50 g), number of leaves per shoot (61.75), and leaf yield per plant (3.00 kg). The cultivation of tree-type mulberries is particularly adaptable to a 6' x 6' spacing.
