Jabon putih (Neolamarckia cadamba) is a widely distributed potential fast-growing species and is thought to be associated with extensive genetic diversity. The aim of the research was to assess the morphological and genetic variation of jabon putih seedling based on AFLP markers. Randomized block design with 4 replications was used to assess seedling morphological variation on 31 families from 4 populations (Kapuas, Kampar, Nusa Kambangan, Pomalaa) based on traits of seedling height, diameter, sturdiness quotient, number of leaves, leaf length, and leaf width at nursery. AFLP Analysis System I Kit by using dry leaf samples from each family was used. Characteristics of jabon putih seedlings had variation among populations and families within population. Genetic variation within population based on morphological traits had the similar trend with result of AFLP analysis. The highest genetic variation was detected in Kapuas population, followed by Pomalaa, Nusa Kambangan, and Kampar populations. Cluster analysis and UPGMA method had 2 cluster and put down most of families from Kapuas in one cluster separated from other families. Based on the genetic similarity analysis, 26 families could be considered as potential families for the establishment of breeding populations. The study has important practical implications for genetic resources management and for future breeding programs of jabon putih.

Background: Sunnhemp is a very important green manuring crop. The crop is utilized for various purposes like reducing soil erosion, improving soil properties and recycling plant nutrients. The knowledge regarding the crop is still not exploited, due to lack of research in this crop. So, the present study was conducted to know the extent of genetic diversity present in the crop. From the divergence analysis, it may be concluded that the genotypes belonging to different clusters separated by high estimated statistical distance may be used in the hybridization programme for developing high green biomass yielding sunnhemp varieties. Methods: A field experiment was conducted at the research farm of Department of Genetics and Plant Breeding, Navsari Agricultural University, Navsari, Gujarat with thirty sunnhemp genotypes to know the extent of genetic diversity by D2 analysis in a randomized block design during late Kharif 2017.Result: The analysis was conducted for D2 analysis and was concluded from D2 analysis that, the characters viz., days to 50% flowering, fresh weight of root nodules per plant, fresh weight of plant, root nodules per plant, leaf length, root length, dry weight of root nodules per plant, C: N ratio, internodes per plant, plant height and stem diameter contributed towards the genetic divergence. Traits like primary branches per plant and leaf area didn’t contribute towards genetic divergence. The thirty genotypes were grouped into seven clusters following Tocher’s method (Rao, 1952). The cluster III was largest having eleven genotypes. Cluster IV and cluster II was second largest which contained seven and five genotypes respectively. Cluster I and cluster V contained three and two genotypes respectively Cluster VI and VII had only one genotype. The intra cluster distance was more in cluster III and the inter cluster distance was maximum between cluster V and cluster VII.

The objective of this study was to estimate the genetic diversity among yam bean landraces collected from different islands of Indonesia based on morphological traits. Thirty-six selected yam beans accessions from diverse ecological regions of Indonesia and six accessions from South and Central America were examined. Field trials were performed at two locations in Bogor, Indonesia, in a randomized block design with two replications. Genetic diversity between accessions based on morphological traits was determined by multivariate analysis. Time to flowering, first pod development, leaf length, leaf width, and internodes length played essential role in classification of the yam beans. A clear separation among the yam bean accessions collected from Indonesia, i.e., Sumatra landraces and the landraces collected from eastern Indonesia was detected. Furthermore, American accessions are not obviously separated from Indonesian yam bean materials.

The objective of this study was to estimate genetic parameters of quantitative traits in a living germplasm collection of Eugenia dysenterica. The genetic material consisted of 110 progenies derived from 10 natural Eugenia dysenterica subpopulations sampled in the southeastern region of the state of Goiás. The experiment was established in a complete randomized block design, with 110 treatments, four replications and one tree per plot. The study variables were total height, stem diameter and respective growth rates. After the analysis of variance some genetic parameters were estimated. The levels of genetic variation in the collection were high and the highest proportion was found within subpopulations. Highest coefficients of heritability and genetic variation were observed in subpopulations from the counties Catalão, Três Ranchos, Cristalina and Senador Canedo. Considering the promising expected progress for growth traits, this collection can be converted into an unrogued seedling seed orchard, aiming the production of improved seed.

Intra- and inter-specific genetic variation analysis was conducted using amplified fragment length polymorphism (AFLP) profiling in Capsicum accessions in the germplasms collected from different geographical locations in India. A total of 24 accessions were investigated belonging to six species, namely C. annuum, C. baccatum, C. chinence, C. eximium, C. frutescens and C. luteum. Average similarity within the 15 accessions of C. annuum was highest (100%) between accessions CIMAP/CA45 and CIMAP/CA49 obtained from IISR, Kerala and 43% among the species CIMAP/CC1 and CIMAP/CB2. In this analysis, accessions were clustered more pronouncedly according to their geographical locations than to their taxonomic labels. A great degree of intermixing of present day domesticated chillies is evident from the present study.

Genetic variation in Lactuca serriola, the closest wild relative of cultivated lettuce, was studied across Europe from the Czech Republic to the United Kingdom, using three molecular marker systems, simple sequence repeat (SSR, microsatellites), AFLP and nucleotide-binding site (NBS) profiling. The ‘functional’ marker system NBS profiling, targeting disease resistance genes of the NBS/LRR family, did not show marked differences in genetic diversity parameters to the other systems. The autogamy of the species resulted in low observed heterozygosity and high population differentiation. Intra-population variation ranged from complete homogeneity to nearly complete heterogeneity. The highest genetic diversity was found in central Europe. The SSR results were compared to SSR variation screened earlier in the lettuce collection of the Centre for Genetic Resources, the Netherlands (CGN). In the UK, practically only a single SSR genotype was found. This genotype together with a few other common SSR genotypes comprised a large part of the plants sampled on the continent. Among the ten most frequent SSR genotypes observed, eight were already present in the CGN collection. Overall, the CGN collection appears to already have a fair representation of genetic variation from NW Europe. The results are discussed in relation to sampling strategies for improving genebank collections of crop wild relatives.

An experiment consisting of four phosphorus levels (0, 40, 60 and 80 kg/ha P2O5) and five zinc levels (0, 10, 20, 30 and 40 kg/ha ZnSO4) was laid out in randomized block design in factorial mode to find out the effect on yield and quality of fodder cowpea [Vigna Unguiculata (L.)Walp.]. Growth parameters viz. plant height, number of leaves, number of branches, leaf length, leaf width and leaf stem ratio were improved with the application of 60 kg/ha P2O5 and 20 kg/ha ZnSO4. Application of 60 kg/ha phosphorus recorded 27.64 t/ha yield, which was 7.50 and 55.6 % higher than 40 kg/ha and no phosphorus application, respectively. Application of zinc in the form of ZnSO4 @ 20 kg/ha increased significantly the green fodder yield (25.89 t/ha). Interaction effect of phosphorus and zinc application was found significant with respect to green fodder, dry matter yield and nutrient uptake. Yield, phosphorus and zinc uptake in cowpea fodder were showing declining trend at combination of application rate more than 60 kg/ha P2O5 and 20 kg/ha ZnSO4.

ABSTRACT Most sandy soils have low natural fertility and low levels of organic matter, making nitrogen (N) fertilization essential. Thus, five doses of N were applied (0, 75, 125, 175 and 225mg dm-³) in a randomized block design to evaluate the effects of nitrogen fertilization on the morphogenetic, structural and production characteristics of Brachiaria brizantha cv. Marandu in a Quartzarenic neosoil. The doses of N did not affect the height of the canopy. The leaf elongation rate, final leaf length and number of live leaves increased linearly at the doses of N. Leaf appearance rate, stem elongation rate, leaf lifespan, phyllochron, leaf senescence rate and tiller density showed a quadratic response to the rates There was also an effect of N rates in herbage mass, leaf mass, stem mass, which increased linearly. Brachiaria brizantha cv. Marandu cultivated in Quartzarenic neosoil requires higher doses of N, 175 and 225mg dm-³. Under these conditions, increases in its morphogenetic, structural and productive characteristics are observed. These findings may not be repeated in the most fertile soils with the greatest capacity to supply N.
