Firstly thirty two genotypes of the species, collected from different areas, were evaluated for growth traits, mineral nutrients and proximate principles after four years in a previously raised progeny trial. In this way top eighteen genotypes were selected and grafted separately on seedling stock of the same species and a clonal seed orchard was established which consisted of eighteen clones (grafted) raised in RBD with three replications. After five years the observations were recorded on individual ramet viz; plant height, basal diameter, leaf width, leaf length, number of branches, petiole length and green leaf yield. Significant differences among clones were observed for different morphometric traits. Various genetic parameters and correlation coefficients for different growth characters were determined. The highest percent GCV (33.20) and PCV(36.02) as also heritability (84.95) were exhibited by green leaf yield while maximum GA (3.23) was noticed in leaf width. The highest percent GG (61.86) was recorded for green leaf yield. Significantly positive correlations were observed between plant height and basal diameter (0.6086), plant height and green leaf yield (0.8461), basal diameter and green leaf yield (0.6924), leaf width and leaf length (0.6490), leaf width and green leaf yield (0.5688) and leaf length and green leaf yield (0.4225).

Evaluation Trial

Variation among different traits along with their correlation were studied in twenty seven clones of Morus alba . The significant differences were found among clones with respect to various morphometric traits. Moderate phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability and genetic gain were recorded for green leaf yield, ramet height, leaf length, leaf width and basal diameter indicating that these characters can be more reliable for effective selection in future. Ramet height showed positive and significant correlation with basal diameter (0.5287), leaf length (0.4671), number of branches (0.6043), and green leaf yield (0.6893). Basal diameter, leaf length and leaf width also exhibited positive and significant correlation with green leaf yield i.e. 0.4705, 0.5714, 0.4813, respectively. Hence, these correlations can be useful in the indirect selection of the species.

Morphological, phenotypical and yield attributing characteristics of 20 mulberry genotypes were evaluated. Genotypic and phenotypic variations, heritability, genetic advance and correlation co-efficient were also estimated. It was found that the phenotypic co-efficient of variation (PCV) was higher (97.68%) than genotypic co-efficient of variation (GCV, 96.99%). The broad sense heritability for these traits ranged from 98.60 (AL) to 4.69 (LLS). High heritability coupled with high genetic advance was recorded for the characters apex length (AL), leaf length (LL), leaf width (LW), leaf petiole ratio (LPR) and petiole length (PL) suggesting the higher genetic control over these traits. Significant positive correlations to leaf yield/plant were observed for the characters, namely total shoot weight (0.817), longest shoot length (0.600), total branch height (0.596) and leaves fresh weight/10 leaves (0.425). Leaf yield showed significantly positive phenotypic and genotypic correlations with all other growth traits (viz., total shoot weight 0.817, length of longest shoot 0.600, total branch height 0.596 and leaves fresh weight/10 leaves 0.425) except total branch number, nodes per meter, leaf width and petiole length. High genetic advance as percentage of mean coupled with heritability was observed on AL, LL, LW, LPR, PL and 10 fresh leaves weight suggesting the prevalence of additive gene action with low environmental influence for the determination of these characters and could be effective in phenotypic selection. Analysis of variances (ANOVA) for characters such as AL, LL, LW, LPR and PL showed significant variations among the genotypes. Since mulberry is mainly cultivated for leaf yield, genotypes having higher AL, LL, LW and LPR and PL must be given importance during parent selection to evolve high yielding varieties across different seasons in mulberry.

Morphometric Characters

Measurements of plant traits are required for evaluating community structure and its ecological responses to varying environmental conditions. The grouping on the basis of functional traits of plants has strong predictive power of important ecosystem responses to environmental perturbation. The morphological traits and their interrelationship among associated species have been analyzed to understand the quantitative variation within regional sal dominated forests. Data for five morphometric traits viz., plant height, leaf length, leaf width, flower size and fruit size, were observed for 193 woody (tree, shrub and liana) species belonging to 56 families within understorey of sal forest. Forty-one families were polytypic in nature. One-way ANOVA was used to detect how variation among all the traits was distributed among habit groups. A significant positive relationship was noticed between plant height and each of the leaf length, leaf width and fruit size. Of the different morphometric traits observed only plant height and fruit size showed wider variation among three life–form categories. Overall, our results suggest that measurement of plant morphometric characters are the major drivers of understory sal associates of the region. Hence, the morphological traits of sal associates should be carefully considered in framing the management and conservation strategy of regional sal forests.

Genetic and phenotypic parameters for height, diameter at breast height (dbh), and volume were estimated for Pinus kesiya Royle ex Gordon clonal seed orchard in Malawi using an ASReml program, fitting an individual tree model. The data were from 88 clones assessed at 18, 23, 30, 35, and 40 years of age. Heritability estimates for height, dbh, and volume were moderate to high ranging from 0.19 to 0.54, from 0.14 to 0.53, and from 0.20 to 0.59, respectively, suggesting a strong genetic control of the traits at the individual level, among families, and within families. The genetic and phenotypic correlations between the growth traits were significantly high and ranged from 0.69 to 0.97 and from 0.60 to 0.95, respectively. This suggests the possibility of indirect selection in trait with direct selection in another trait. The predicted genetic gains showed that the optimal rotational age of the Pinus kesiya clonal seed orchard is 30 years; therefore, it is recommended to establish a new Pinus kesiya clonal seed orchard. However, selective harvest of clones with high breeding values in the old seed orchard should be considered so that the best parents in the old orchard can continue to contribute until the new orchard is well established.

Considerable diversity exists in Capsicum L. germplasm for fruit and leaf shape, size, and color as well as plant habit. Using F1, F2, and backcross generations developed from diverse parental stocks, this report describes the inheritance patterns and relationships between unique foliar characters and diverse fruit and plant habit attributes. Our results demonstrate that pepper fruit color, shape, and fruit per cluster were simply inherited with modifying gene action. Broad-sense heritability for fruit color and shape and fruit per cluster was high, whereas narrow-sense heritability for these characters was moderate to low. Although fruit clustering was simply inherited, the number of fruit per cluster exhibited a quantitative mode of inheritance. High fruit counts per cluster were linked with red fruit color and anthocyanin pigmented foliage. Fruit shape was linked with immature fruit color and inherited independently of mature fruit color. Leaf color, length, and plant height were quantitatively inherited. Leaf shape did not vary, but leaf length varied and was positively correlated with leaf width. Broad-sense heritability for leaf characters, including leaf length, leaf width, and leaf color, was high. With the exception of leaf width, which exhibited low narrow-sense heritability, high narrow-sense heritability for leaf characters denoted additive gene action. Plant height displayed high broad-sense heritability. Moderate narrow-sense heritability suggested that additive effects also influence plant height. Analysis of segregating populations demonstrated that red and orange fruit color can be combined with all possible leaf colors from green to black. These results provide new data to clarify and extend available information on the inheritance of Capsicum fruit attributes and provide new information on the genetic control of leaf characters and plant habit.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

The study pertaining to the effect of summer season on correlation analysis in bird of paradise (Strelitzia reginae) was carried out among forty progenies. The results of correlation analysis for twelve parameters (plant height, stem girth, leaf length, leaf width, number of leaves per plant, number of suckers/m 2 , flower stalk length, flower stalk girth, spath length, no. of bracts, vase life and no. of flowers/ m 2 ) at genotypic and phenotypic levels revealed that number of flowers per m 2 of progenies during summer, 2011 showed positive and significant correlations with plant height (0.357 and 0.237) and number of suckers/ m2 (0.880 and 0.899). Whereas, it showed positive and significant correlation with stem girth (0.203), leaf width (0.202) and flower stalk girth (0.265) at genotypic level only. While during summer 2012, number of flowers per m 2 showed positive correlations with plant height (0.265 and 0.242), stem girth (0.232 and 0.215), number of suckers/ m 2 (0.913 and 0.900) and flower stalk length (0.268 and 0.249) at genotypic and phenotypic levels. Hence, the selection of these characters would be effective in improving yield in bird of paradise crop.

Ten genotypes of maize collected from National Center for Genetic Resources and Biotechnology (NACGRAB) were induced with X-ray for morphological and molecular assessment. The experimental design was complete randomized design with four replicates. Morphological and molecular statistical analyses of treated genotypes were conducted using SAS and Power Maker Packages, respectively while dendrogram was generated using Jaccards similarity coefficient using Unweighted Paired Group Method and Arithmetic Averages (UPGMA). The study revealed significant difference which is an indication of genetic variation of characters in treated maize. Genotype DTSR-Wco performed best in plant height (62.35 cm), leaf length (62.35 cm), number of leaves (3.15), leaf width (7.55 cm) and dry leaf biomass (0.24 g). X-ray at 90 Kv/mass, 95 Kv/mass and 100 Kv/mass decreased plant heights to 54.25cm, 53.87cm and 54.10cm respectively compared to Control. Heritability estimate was greater than 70% for all characters evaluated. Genotype TZM 1551 at 0 Kv/mass yielded the highest concentration of DNA at 2841.60 ng/ul and the highest genomic DNA concentration was obtained at 95 Kv/mass for TZM 132 with 1.91%. Primer BMC 1755 was most polymorphic with 58.77% in treated maize genotypes. The plant height was strongly correlated with leaf length (r=0.9), leaf width (r=0.76) and number of leaves (r=0.77). Principal component analysis showed close relationship between plant height (-0.03) and leaf length (0.05) compared with leaf width (-0.67) and number of leaves (0.69). Dry shoot biomass (0.05) was closely related to dry root biomass (-0.03) and dry leaf biomass (-0.04).
