Ramadiana S, Hapsoro D, Yusnita Y. 2018. Morphological variation among fifteen superior robusta coffee clones inLampung Province, Indonesia. Biodiversitas 19: 1475-1481. This study aimed to characterize morphological variation among fifteensuperior robusta coffee clones in Lampung Province. The fifteen clones consisted of four clones released by the Indonesian Coffee andCocoa Research Institute (ICCRI), i.e. ‘BP 409’,‘BP936’, ‘BP939’, ‘SA 237’, together with eleven superior coffee clones selected byfarmers from Tanggamus District (‘Tugino’, ‘Wanto’, ‘Biyadi’, ‘Komari’, ‘Wardi’, ‘Wariso’) and from West Lampung District (‘TuguKuning’, ‘Tugu Hijau', ‘Tugu Biru', ‘Tugu Sari', ‘Lengkong'). Fifteen qualitative and seven quantitative morphological characters wereevaluated in a randomized complete block design with three replicates for each clone,each replication consisted of two plants. Fromeach plant, four samples were taken from four sides of the plant (north, south, west, and east). It was found that while somemorphological characters exhibited negligible variation among clones, there were significant differences between clones for othercharacters. The characters that did not differ significantly between clones were: shapes of leaf base and leaf tip; petiole color; leafvenation pattern; fruit disk shape; ripe-fruit color; and stipule shape. The characters that varied between clones were shape of leaf lamina(elliptical vs. lanceolate); fruit shape (round vs. oval); and shape of leaf margins. Morphological variation was also observed in somequantitative characters: canopy diameter; tree height; stem diameter; leaf length; leaf width; petiole length; stipule length; and number ofprimary branches.

ABSTRACT Studies on the effect of transplanting methods and NP – fertilizer rates on leaf length of a female date palm offshoot have been conducted over a period of 25 months (September, 2017 – September 2019). The trial was sited at the Date Palm Research Sub – station/ Federal University Dutse (11o50’N, 09o25’E) in the Sudan Savanna ecological zone of Nigeria.  The treatments consisted of two transplanting methods (Direct: detachment of offshoot from the parent palm and directly transplanting into the field, and Indirect: detachment of offshoot from the parent palm and keeping in the nursery for 3 months before transplanting into the field) and five NP fertilizer rates Control (0g N + 0g P), 80g N + 40g P, 160g N + 80g P, 240g N +120g P and 320g N + 160g P) arranged in a randomized complete block design with three replications. Indirect transplanting of date palm through nursery proved more effective than direct transplanting as it produces statistically longer leaves which are an indication of better chances of crop survival, establishment and yield. Rate 320g N +160g P statistically outperformed other rates in the production of longer leaves throughout the sampling periods. Interaction between transplanting methods and fertilizer rates was highly significant in most of the sampled periods except in June and September, 2019. A combination of indirect transplanting method with rate 320g N +160g P that produced longer leaves is recommended for adoption  in the Sudan Savannah ecological zone of Nigeria.

ABSTRACT<br /><br />Indonesia is one of the largest wheat importers. Suitable environmental condition for wheat needs to be studied if wheat is going to be widely cultivated in Indonesia. The adaptability of wheat grown in various climates and altitudes is one of the important aspects. The objective of this experiment was to study the quantitative and morphological character of wheat grown in middle land (540 m asl) in Bogor, West Java. The experiment was arranged in randomized complete block design with three replications. Wheat genotypes used were three national varieties (Nias, Selayar, and Dewata), four new improved varieties (Guri 3 Agritan, Guri 4 Agritan, Guri 5 Agritan, and Guri 6 Unand), and one introduced genotype (SBD). Data were collected for several quantitative variables and seventeen morphological characters based on UPOV descriptor. The result showed that wheat growth was restricted in Bogor. Genotype determined plant height, leaf number, ear length, root length, number of spikelet, harvest time, seed weight, number of tillers, and plant biomass. Based on ear length, grain weight, and plant biomass, Guri 3 Agritan had the highest production than the other genotypes.<br /><br />Keywords: diversity, genetic relationship, high temperature, introduced genotype, phylogenetic<br /><br />

Abstract. Sahid ZD, Syukur M, Maharijaya A. 2020. Genetic diversity of capsaicin content, quantitative, and yield component in chili (Capsicum annuum) and their F1 hybrid. Biodiversitas 21: 2251-2257. Chili (Capsicum annuum L.) is one of the horticultural plants that have many benefits. The benefit of chili was determined by pungency level of its fruit. Pungency level of the chili is due to the capsaicin content in fruit. Information about the genetic diversity of capsaicin is still rarely available. The aims of this study were to obtain diversity information on quantitative, yield component, and capsaicin content, and to analyze the correlation among chili genotypes based on their morphological characters. This study used Randomized Complete Block Design with three replications. The genetic material used in this study consisted of 21 genotypes consisting of 6 genotypes of chili elders and 15 hybrid F1 genotypes resulting from their crossing. Six genotypes of the chili parents are C5, F6074, F9160291, Yuni, Bara, and Giant. 15 hybrid F1 genotypes used in this study are C5 x Bara, C5 x F6074, C5 x Yuni, C5 x Giant, C5 x F9160291, Bara x F6074, Bara x Yuni, Bara x Giant, Bara x F9160291, F6074 x Yuni, F6074 x Giant, F6074 x F9160291, Yuni x Giant, Yuni x F9160291, and Giant x F9160291. The observation was made on the variables of quantitative, yield, and capsaicin components on chili. The results showed that the highest capsaicin content only was found in Bara x F9160291. The results of scatterplot analysis showed that the highest capsaicin and yield component was found in BaraxF6074 and C5 x Yuni genotype. The results of cluster analysis showed that chili was clustered into three color groups. The character of capsaicin content is negatively correlated and very different from fruit weight, fruit diameter, fruit length, thick fruit flesh, total amount of fruit per plant, and fruit weight per plant.

The experiment was conducted in the Dekarhaor of Noagaon village under South Sunamganj Upazila of Sunamganj district during November 2017 to February 2018 to observe the effect of nutrients management on growth and yield of cauliflower hybrids. Two Hybrids namely ShiraGiku (V1) and Rupali (V2), and four combinations of nutrients, viz. (i) recommended rate of N-P-K-S-Zn-B @ 180-80-180-28-4.5-2.1 kg ha-1(F1), (ii) F1 + 25% N-P-K- S-Zn-B of F1 (F2), (iii) F1 – 25% N-P-K-S-Zn-B of F1 (F3), and (iv)  cow dung @ 10 t ha-1 (F4)  was conducted in a factorial randomized complete block design (RCBD) and replicated thrice. Plant height (cm), numbers of leaves plant-1, leaf length (cm) and leaf breadth (cm), and spreading diameter (cm) were collected at 15 days intervals, while the yield data were recorded at harvest. The parameters were significantly varied due to hybrids and fertilizers packages. Higher gross yield (42.52tha-1) was found in Shira Giku and lower (42.12 t ha-1) from Rupali. Higher curd yield of 25.17 t ha-1 was obtained in Shira Giku than Rupali (9.61 t ha-1). The highest gross yield of 44.45 t ha-1 was obtained when the crop was treated with cowdung @ 10 t ha-1 followed by recommended fertilizer rate (F1). The curd yield of 18.19 t ha-1 was obtained with 25% less than recommended fertilizer rate of application (F3). The highest gross yield of 52.93 t ha-1 was obtained in V1F1 combination and the lowest of 30.10t ha-1in V2 F1. Results revealed that the Hybrid ShiraGiku with recommended dose of fertilizer (180-80-180-28-4.5-2.1 kg ha-1N-P-K-S-Zn-B) performed the best in comparison to other treatment combinations.

Ex-situ conservation plot of kayu merah (Pterocarpus indicus Willd) has been established in Gunungkidul in2016. The purpose of this study was to observe the early growth of kayu merah in the plot at 2 years old. The plot was laid-out in randomized complete block design consisting of 68 families, 4 tree-plot and 5 blocks with spacing of 3 m × 3 m. Genetic materials of kayu merah were collected from 3 populations namely Timor, Flores and Seram. Measurement was conducted in survival rate, tree diameter, tree height and number of branches. The result showed that the average survival rate of family was high (≥80%). Based on the populations, the survival rate of Timor, Flores and Seram were around 95%, 96% and 96.5% respectively. The average height, diameter and number of branches were 275 cm, 2.79 cm and 1.66, respectively. There were significant differences for height, diameter and number of branches among the tested families. In general, family ranking varied among the measured traits. Correlation between the traits varied among the populations. The Seram population showed the top family ranking for all the traits. It indicated that characterization in ex-situ conservation plot using genetic materials collected from the three populations was important for further conservation program of kayu merah.

Foxtail millet (Setaria italica L. Beauv) categorized as an underutilized crop in Nepal persist a large diversity among different germplasms and accessions found in the country. Ten foxtail millet accessions were collected from different parts of Nepal and were evaluated for assessing the diversity in different characters at Institute of Agriculture and Animal Science, Rampur, Chitwan. The accessions were experimented in Randomized Complete Block Design with three replications. Observations were taken for qualitative traits i.e. tip of first leaf, anthocyanin at leaf base, lobe compactness, length of bristles, anthocyanin presence, leaf blade altitude, flag leaf color, lobe in panicles, panicle lodging, inflorescence compactness, overall color, panicle anthocyanin, panicle shape and growth habit. Shannon Weiner index and Evenness were calculated to assess the diversity in the accessions under study. The maximum number of diversity in traits of lobe compactness of panicle (1.3624) followed by panicle lodging (1.1595), inflorescence compactness (1.1235) and length of bristles (1.0681). Least diversity was observed in trait of growth habit (0.3926) followed by panicle anthocyanin coloration (0.4505) and lobes in panicles (0.5799). The finding of existence of wide diversity in the studied accessions could be a pivotal information for further study of genetic variation of foxtail millet germplasms.Int J Appl Sci Biotechnol, Vol 4(4): 483-488

Abstract With the advances in high-throughput sequencing technologies, it is not difficult to extract tens of thousands of single nucleotide polymorphisms (SNPs) across many individuals in a fast and cheap way, making it possible to perform genome-wide association studies (GWAS) of quantitative traits in outbred forest trees. It is very valuable to apply traditional breeding experiments in GWAS for identifying genome variants associated to ecologically and economically important traits in Populus. Here, we reported a GWAS of tree height measured at multiple time points from a randomized complete block design (RCBD), which was established with clones from an F1 hybrid population of Populus deltoides and Populus simonii. A total of 22,670 SNPs across 172 clones in the RCBD were obtained with restriction site-associated DNA sequencing (RADseq) technology. The multivariate mixed linear model was applied by incorporating the pedigree relationship matrix of individuals to test the association of each SNP to the tree heights over 8 time points. Consequently, 41 SNPs were identified significantly associated to the tree height under the p-value threshold determined by Bonferroni correction at the significant level of 0.01. These SNPs were distributed on all but 2 chromosomes (Chr02 and Chr18) and explained the phenotypic variance ranged from 0.26% to 2.64%, amounting to 63.68% in total. Comparison with previous mapping studies for poplar height as well as the candidate genes of these detected SNPs were also investigated. We therefore demonstrated that the application of multivariate linear mixed model to the longitudinal phenotypic data from the traditional breeding experimental design facilitated to identify far more genome-wide variants for tree height in poplar. The significant SNPs identified in this study would enhance understanding of molecular mechanism for growth traits and would accelerate marker-assisted breeding programs in Populus.

<em>The estimated value of genotype variability, phenotype variability, environmental variability, and heritability have an important role in breeding activities of tea</em> <em>in order to create the superior varieties. The objective of this study was to investigate the phenotypic performance, genotype and phenotype variation, and heritability value of nine genotypes of tea. The study was conducted at Pemandangan block, Tambi Plantation Unit,  Wonosobo, Central Java, from April 2013 until April 2014. The Randomized Complete Block Design (RBD) with nine treatments and three replications was used in this study. The 9<sup>th</sup> of treatments consisted of 2 genotypes of tea resulting from a cross (GMB 3 and GMB 4), 2 introduced genotypes (TRI 2024 and TRI 2025), and 5 local genotypes resulting from selection (Cin 143, Kiara 8, RB 3, Tambi 1, and Tambi 2). The results showed that the genotype of GMB 3 more higher than other genotypes in pecco length, leaf length, leaf width, length of leaf stalk, and length of leaf internodes characters, whereas Tambi 2, GMB 3, and GMB 4 more higher in fresh weight of P+2 and P+3. The production of fresh shoot of GMB 4 more higher than the other genotypes, but not significant with GMB 3 and RB 3. The leaf length and fresh shoot production characters has a wide of genotype and phenotype variability, whereas the high of heritability value were found in all characters observed. The selection based on leaf length and fresh shoot production characters will be effective because both characters have a high genotypes variability and heritability.</em>

Crambe cultivation has expanded in Brazil. The species is a promising alternative for biodiesel production since its seed contain great amounts of oil. Nevertheless, only few studies have focused on the growth and nutritional requirements of crambe cultivated in acidic soils. Thus, this study aimed to evaluate the effects of liming on the growth and nutrient accumulation of crambe cultivated in a Yellow Latosol of medium texture. The experiment was carried out using a randomized complete block design. The treatments consisted of different soil base saturation levels (0%, 20%, 40%, 60% and 80%) with five replications. Plant height, leaf length, leaf width and the number of seeds were evaluated 90 days after planting. The plant material was separated into leaves, stem, seeds and roots, which were oven dried at 70 ºC until constant weight. Analysis of variance was performed, followed by data regression when significant at 5% probability level by the F test. Crambe responded positively to liming in the soil under study at a base saturation of 56.95% as a function of the biometric variables. The increase in the base saturation of the soil to up to 60% promoted a drastic reduction in plant growth and, therefore, in the final grain yield. The decreasing order of the leaf nutritional content at 56.95% base saturation was: N>Ca>K>Mg>S>P>Fe>B>Mn>Zn> Cu.
