Limitations in obtaining superior varieties of red chili that are suitable to be planted in the highlands are one of the causes of the low yield of red chili in Rejang Lebong Regency. However, the availability of red chili germplasm as a genetic resource (SDG) in Rejang Lebong Regency is a good potential to be utilized to overcome problems in increasing the yield of red chili plants through the assembly of superior varieties. Assembling superior varieties of red chili has been done by researchers in order to get the desired plant character. This study aims to obtain information on the variability and heritability of growth character and yield of 18 red chili varieties in Rejang Lebong Regency. This research activity is the initial activity of developing the potential of germplasm that will be carried out so as to be able to overcome the problems in increasing the production of red chili in Rejang Lebong Regency. A series of research activities will produce superior varieties of red chili specifically for the highlands. The material used in this study was eighteen (18) varieties of chilli collections from various regions. The experimental design used was a Complete Randomized Block Design (RCBD) with a single factor, namely red chili plant varieties. The red chili varieties to be investigated for genetic variability and heritability in this study amounted to 18 and each treatment was repeated three times. The results showed that the highest estimated heritability was indicated by the leaf width variable at 96.69% and all observed variables had broad genotypic and phenotific variability.

ABSTRACT The objectives of this work were to study the genetic variability and the interaction between genotypes and environments for cooking time and protein content of bean grains as well as to identify elite lines of Carioca grain type with short cooking time, high protein content and high adaptability and stability for these two traits. Sixteen experiments were conducted in a complete randomized block design with three replications during the rainy, dry and winter seasons, in Goiás, Distrito Federal, Pernambuco, Sergipe, Bahia and Paraná States, in 2009 and 2010. Each trial was composed by 16 elite lines of Carioca grain type and the data of cooking time and protein content were obtained. Data were submitted to analysis of variance and to stability and adaptability analysis, according to the methodology proposed by Annichiarico. Genetic variability was found for cooking time and for protein content among Carioca common bean elite lines; however, for protein content this variability is lower. The environmental effect is important for the expression of these traits and is larger than the genetic effect. The interaction between genotypes and environments is important for cooking time and for protein content of common beans. The lines CNFC 11951 and CNFC 11962 presents short cooking time, high protein content and high stability and adaptability for both traits.

ABSTRACT The interaction Fusarium oxysporum f. sp. cubense (Foc) x nematode and the genetic variability of Foc are the main problems with potential to affect the use of resistant varieties in the management of the Panama disease. The objective of this work was to evaluate the interaction between Foc and Meloidogyne javanica on the banana of the Prata Anã, Grande Naine and BRS Princesa cultivars. The experiment was conducted in a randomized block design, with six treatments and ten replications, which differed in the inoculation time of each pathogen. Simultaneous inoculation with Foc and M. javanica, inoculation with Foc one week before inoculation with M. javanica, and inoculation with M. javanica one week before inoculation with Foc. In addition to the controls, Foc isolated, M. javanica isolated, and cultivars without the pathogens. The seedlings were transplanted in 3-liter pots with sterile soil infested with 40 grams of Foc inoculum at the concentration of 1x106CFU/gram and 1000 eggs and J2 of M. javanica. At the end of 56 days, the treatments with 'Grande Naine' presented the highest reproduction factors of M. javanica. In the 'Prata Anã' no interaction was observed between Foc x M. javanica. The treatments with simultaneous inoculation of the two pathogens, and with Foc a week before, in the 'BRS Princesa', presented the highest external disease indices (DI), which promoted the highest AUDPC. The highest internal DI were observed in the treatments Foc+Mj+Grande Naine, Foc+Mj+BRS Princesa, Mj+Grande Naine+Foc and Foc+BRS Princesa+Mj. The simultaneous presence of M. javanica and Foc increases the severity of the Panama disease in Grande Naine and BRS Princesa cultivars.

Abstract. Alhamdi MFF, Setiawan A, Ilyas S, Ho WK. 2020. Genetic variability of Indonesian landraces of Vigna subterranea: The morphological characteristics and molecular analysis using SSR markers. Biodiversitas 21: 3929-3937. Bambara groundnut (Vigna subterranea (L.) Verdc.) is a potential grain, which can be considered as an alternative source of protein and carbohydrate. Due to unavailability of commercial bambara groundut cultivar in Indonesia, the characterization of bambara groundnut landraces is an important step before developing cultivar with traits of interest. The objective of the research was to access genetic variability of Indonesian landraces of bambara groundnut with different seed coat colors based on morphological and molecular markers. The experiment was arranged as split-plot in a complete randomized block design with the main plot was cultivation methods and the sub plot was landraces. There were differences in leaf shape and pod shape among the landraces. There were two main clusters of Indonesian landraces of bambara groundnut with 88.28% similarity. The first cluster was Cream, Brown Sumedang, Black Sumedang and Black Tasikmalaya, and the second cluster was Black Sukabumi, Brown Gresik, Black Madura, and Black Gresik. The result based on SSR marker with capillary electrophoresis indicated Black Gresik and Black Madura landraces were different from other Indonesian landraces.  Cream Sumedang or Brown Sumedang from the first cluster and Black Gresik or Brown Gresik from the second cluster have the farthest distances for developing improved variety of bambara groundnut.

Ciplukan (Physalis sp.) merupakan salah satu tumbuhan yang potensial untuk dikembangkan sebagai sumber biofarmaka dan buah di Indonesia. Peningkatan produksi ini dapat dilakukan melalui penyediaan varietas-varietas unggul ciplukan dengan meningkatkan kapasitas genetik melalui program pemuliaan tanaman. Pemuliaan tanaman akan berhasil jika terdapat keragaman genetik yang luas dan heritabilitas tinggi. Penelitian ini bertujuan untuk mempelajari keragaman genetik dan heritabilitas pada karakter komponen hasil dan hasil ciplukan. Percobaan menggunakan rancangan acak kelompok dengan 34 aksesi ciplukan sebagai perlakuan diulang tiga kali. Penelitian dilaksanakan di Kelurahan Areng-Areng, Kecamatan Junrejo, Kota Batu pada bulan Mei - September 2017. Karakter pada tanaman ciplukan ada yang mempunyai keragaman luas dan ada yang mempunyai keragaman sempit. Keragaman yang luas terdapat pada tinggi batang, jumlah bunga per tanaman, bobot per buah tanpa kelopak, bobot per buah dengan kelopak, jumlah buah per tanaman, jumlah buah segar per tanaman, bobot buah per tanaman dan bobot buah segar per tanaman. Keragaman yang sempit terdapat pada karakter diameter batang, jumlah cabang tersier, jumlah bunga per cabang tersier, panjang tangkai buah, panjang kelopak, diameter kelopak, panjang buah, diameter buah, dan kemanisan buah. Nilai heritabilitas pada semua karakter termasuk kriteria tinggi. Hal ini menunjukkan pengaruh genetik lebih besar dibandingkan dengan faktor fenotip pada penampilan karakter tanaman ciplukan. Ciplukan (Physalis sp.) is one of the potential plant to be developed as a source of medical plant and fruit in Indonesia. Increase production of this plant can be done through the provision of improved varieties of ciplukan by increasing the genetic capacity through plant breeding programs. Plant breeding will be successful if there is high genetic variability and heritability. This study aimed to study genetic variability and heritability on the character of yield component and yield in Physalis. The experiment used a randomized block design with 34 accessions of ciplukan as treatment repeated three times. The research was conducted in Areng-Areng sub-district, Junrejo District, Batu City from May until September 2017. Characters in ciplukan plants have wide and narrow variability. Characters that have a wide variability are stem height, number of flower per plant, number of fruits per plant, number of fruits per plant, weight per fruit without husks, weight per fruit with husk, weight of fruit per plant, and weight of fresh fruit per plant. Characters that have narrow variability are stem diameter, number of tertiary branching, number of flower per tertiary branching, length of fruit stalk, husk length, husk diameter, fruit length, fruit diameter, and sweetness. All characters have high heritability. This shows a greater genetic influence compared to phenotypic factors on the appearance of ciplukan characters. Physalis, genetic variablity, heritabilityKey words :

<p>As a natural mineral that contains several macro elements, polyhalite (K2Ca2Mg (SO4) 4H2O) has good potential as a fertilizer. This study aims to study the effect of polyhalite on branch growth, leaf nutrition (K, Mg and S), chlorophyll index, harvest weight, fruit quality, and the effective dose of Siam citrus. A 4-year-old Siam citrus planted on vertisol soil was treated with 6 fertilizer treatments: 625; 1,000; 1,375; 1,750; 2.125 kg polyhalite and 625 kg ZK/hectare/year. The experiment using a randomized block design was repeated 3 times. The results showed that<br />the application of polyhalite at the same K2O dose as ZK increased leaf Mg content, chlorophyll index and total juicesolids significantly. Polyhalite application of 1,750 kg/hectare (2.8 kg/tree) is an effective dose for mature Siam citrus in vertisol with moderate K status and high Ca and Mg status.</p>

Genetic variability in progenies of Eucalyptus grandis and Eucalyptus urophylla for tolerance to hydric deficit. Information on the adaptation and genetic potential of Eucalyptus under water deficit conditions is necessary owing to the increasing cultivation of the genus in regions considered as "forest frontiers". Therefore, the present study aimed to estimate genetic variability, genotypic and phenotypic correlations, and estimated genetic gains in progenies of E. grandis and E. urophylla. Two progeny tests (TP1 and TP2) were performed in the municipality of Vila Nova dos Martirios (state of Maranhão, Brazil), in 30-month-old plants. The experiment was carried out using a randomized block design, with five replicates, nine plants/square plot, and 144 treatments in TP1 and 264 in TP2. Statistical analysis was performed and genetic parameters were estimated. Individual and within-progeny heritabilities were corrected using the kinship coefficient for eachspecies. Genetic gains were low, ranging from 0.96 to 6.39% for E. grandis and 1.62 to 5.48% for E. urophylla. The diameter at breast height (DBH) showed a higher coefficient of genetic variation compared with the other measured characteristics, suggesting a higher potential for selection. High, positive, and significant correlations were observed between DBH and height (H), indicating the possibility of obtaining gains based on a single characteristic. Heritability was considered low, thus directly influencing the selection gains, which were lower than those commonly reported in other studies. These findings provide important information for breeding programs in areas of forest expansion.

The aim of this study was to determine agronomic characteristics and responses to the coffee leaf rust fungus (Hemileia vastatrix Berk. et Br.) in coffee progenies resistant to the gall nematode Meloidogyne exigua. The experiment was conducted in December 2000 at Ouro Verde Farm (FazendaOuro Verde), located in the municipality of Campos Altos – Minas Gerais (MG). Ten F3:4 progenies were evaluated. They were derived from crosses between CIFC 2570 Timor Hybrid selections and Catuaí cultivars known to be resistant to M. exigua. The Catuaí Vermelho IAC 99 cultivar served as a control. A randomized block design with three replicates was used. In total, there were thirty-three plots consisting of eight plants each. The following characteristics were assessed between the harvests of 2011/2012 and 2014/2015: (a) yield expressed as processed coffee bags ha-1; (b) rust incidence and severity; (c) vegetative vigor; (d) percentage of coffee fruits at the “cherry” stage; (e) percentage of floaters; (f) crown diameter; (g) percentage of coffee beans of size sieve 17 and higher; and (h) sensory analysis of the coffee beverage. The results indicated the following: (a) the H514-7-14-2, H514-7-4-5, H493-1-2-2, H514-7-16-3, H514-7-8-11, H518-2-10-1, and H514-5-2-4 progenies were the most productive; (b) all progenies showed promising resistance to coffee leaf rust; (c) all genotypes had the potential for specialty coffee production; (d) the H493-1-2-2 progeny showed resistance both to rust and the nematode, and has good potential for specialty coffee production; and (e) the yields of the H514-7-8-11, H518-2-10-1, H514-5-2-4, H514-7-16-3, H514-7-14-2, H514-7-4-5, and H493-1-2-2 progenies were significantly higher than that of the Catuaí IAC 99 control.

The objectives of this study were to detect genetic variability among genotypes of Brachiara humidicola, study the genetic diversity and identify redundant variables in the discrimination of hybrids. Fifteen genotypes were evaluated for morphological, agronomic and nutritive characteristics in a randomized block design with six replications, in Rio Branco, Acre. Analysis of variance was performed, followed by the Scott-Knott test. Different techniques of multivariate analysis were used to study genetic diversity. Significant differences in plant performance were observed for agronomic and morphological characteristics, but not for nutritive value. There was consistency between the different clustering techniques. Four redundant characteristics were identified that can be discarded. The existence of divergent and superior hybrids that can be used in recurrent selection (sexual) programs or can be released as new (apomictic) cultivars after testing for animal response was confirmed. The lack of genetic variability in bromatological traits indicates the need for differentiated selection strategies.
