The ability of exotic species to proliferate and expand their range may hinge critically upon their potential for adaptive evolution. The finding of parallel patterns of genetically based clinal variation in native and non-native ranges across similar environmental gradients supports the hypothesis that adaptive evolution has played a role in establishment and spread. In this common garden study, we compared patterns of phenotypic variation among 12 populations of Solidago altissima L. that were sampled across similar latitudes in the native range in central USA (25°N–43°N) and across its invasive range in Japan (26°N–43°N). Significant clinal variation in phenotype corresponding to latitude was found among US and Japanese populations for height, leaf number, leaf length, leaf width, stem diameter, and stomatal guard-cell size. Only the slope of leaf width differed significantly between the native and invasive range, and the slope was significantly steeper in Japan. These results indicate that patterns of selection across latitude are similar in these two countries. We suggest that populations of S. altissima have rapidly differentiated in response to the cline in selection in Japan, possibly by the sorting of lineages from multiple introductions, and this has contributed to their success as an exotic invader.

Research conducted an experiment using a completely randomized design environment with four replications, and the design of treatment used is six varieties of sweet corn. Analysis of data using polynomial regression, the parameters measured were plant height, leaf number, leaf length, leaf width, and sugar beans, followed by analyzing the relationship between the growth of plants with a sugar content of sweet corn kernels. The results showed that leaf width gives a weak relationship to the sugar content of sweet corn seed, and leaf length, number of leaves and plant height had a close relationship to the sugar content of sweet corn kernels.

The arrowroot has low glicemic index, and high carbohydrate content, high quality of flour and can replace position of wheat flour as food material and industry. Evaluation and characterization are needed to get informations of superior characteristic of arrowroot as source of genetic variability to develop promising new arrowroot varieties. The result showed that the morphological characteristic of 20 arrowroot accecions were not different on the qualitative characteristics. The characteristics of leaf colour, stem and stalk leaf colour, and white colour of tuber were not different among arrowroot accecions. The quantitative characteristics of tuber or rhizomes type (tuber length and tuber circle), plant height, number of tiller/hill, total leaf/main stem, leaf length and leaf width among accecions had low variability. The tuber weight per hill had positive correlation with plant height, number of leaf, tuber length and tuber circle and negative correlation with leaf length, leaf width and stalk length leaf.</p><p> </p><p><strong>Abstrak</strong></p><p>Garut (Marantha arundinaceae L.) merupakan sumber pangan yang potensial bagi sebagian masyarakat di Indonesia.

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.

Descriptive Statistical Analysis

Seeds need favorable environmental conditions to germinate but sometimes these conditions are not available. The goal of this work was to evaluate the influence of different concentrations of NaCl on in vitro germination and development of Capsicum annuum seedlings. The experiment was conducted at the Laboratório de Biotecnologia Vegetal at Centro de Ciências Agrárias (CCA) of Universidade Federal da Paraíba (UFPB), Areia, PB, Brazil. Ornamental pepper seeds (Capsicum annuum L.) were submitted to five concentrations of NaCl: 0, 25, 50, 75 and 100 mM. The experimental design was completely randomized, with five treatments and seven replicates, each replicate consisted of one flask with one seed. After 14 days in vitro, the germinated seedlings were characterized for seedling height, hypocotyl width, cotyledon leaf length, cotyledon leaf width, leaf number, radicle length, fresh matter and germination. The data were submitted to analysis of variance by the F test ( p ≤ 0.05). When significant differences were detected, the data were submitted to regression analysis. Percentage of abnormal plantlets was also calculated and submitted to descriptive statistical analysis. The percentage of germination was not affected by the NaCl concentrations used in this work. However 75 e 100 mM salt concentrations influenced the cotyledonary leaf width, total fresh matter and percentage of abnormal seedlings.

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)
