The Relationship

The knowledge of genetic variability and breeding techniques is crucial in crop improvement programs. This information is especially important in underutilized crops such as Bambara groundnut, which have limited breeding systems and genetic diversity information. Hence, this study evaluated the genetic variability and established the relationship between the yield and its components in Bambara groundnut based on seed weight using multivariate analysis. A field trial was conducted in a randomized complete block design with three replications on 28 lines. Data were collected on 12 agro-morphological traits, and a statistical analysis was conducted using SAS version 9.4 software, while the variance component, genotypic and phenotypic coefficient variation, heritability, and genetic advance values were estimated. A cluster analysis was performed using NT-SYS software to estimate the genetic relations among the accessions. The results showed significant variability among the accessions based on the yield and yield component characteristics. The evaluated lines were grouped into seven primary clusters based on the assessed traits using the UPGMA dendrogram. Based on the overall results, G5LR1P3, G1LR1P3, G4LR1P1, G2SR1P1 and G3SR1P4 performed the best for the yield and yield components. These improved lines are recommended for large-scale evaluation and utilization in future breeding programs to develop high-yield Bambara groundnut varieties.

Boro Rice

The success of varietal development programmme largely depends on the nature and magnitude of genetic variability, heritability and characters association of the crop. The objective of the present study was to estimate the extent of genetic variability and relation between yield and related characters of rice. Forty Boro rice germplasm were evaluated in a randomised complete block design with three replications. Analysis of variance indicated significant differences among the genotypes for 14 quantitative characters. The presence of slightly higher phenotypic coefficient of variation than genotypic coefficient of variation indicated the negligible influence of environment on the expression of yield and its component traits. Leaf length, days to flowering, days to maturity and 1000 grain weight showed highly positive significant correlation present with yield hill-1. High heritability had been observed for yield contributing traits during the study, suggested that these traits would respond to selection owing to their high genetic variability and transmissibility. Therefore, a thorough understanding of the inheritance of traits, their heritability and relationship with other important characteristics is important for the choice of breeding and selection methods for crop improvement.

Seed yield of selected Nigerian Bambara Groundnut landraces under two varying water conditions was evaluated. Twenty eight (28) Bambara groundnut accessions were planted in a randomized complete block design with two treatments (Non-water stressed and Water stressed) and replicated five times. The experiment was conducted at the Experimental Garden of the Department of Biological Sciences, Federal University of Technology, Minna, Niger State. The accessions were planted in planting bags during the cropping season of 2016 between July and October. The two treatments were rain fed until maturity except during the period of exposure to water stress where the water stressed plants were transferred to a screen house made with polyvinyl ceiling to prevent water during the flowering stage for two weeks. It was observed that water stress reduced the yield of the Bambara groundnut landraces by 47%. Accessions NGB-01646-B, NGR-NI-20-H  and NGB-01491 which had relatively high yield in the stressed and non- water stressed condition were considered  the most drought tolerant accessions and accession NGR-KG-02-C with low yield both in stressed and non-stressed conditions was identified as the most susceptible accession. Accessions which had high yield only in water stressed conditions could serve as elite line for Bambara groundnut for areas which have problem of drought. These drought tolerant accessions identified in the research can serve as potential parent lines in breeding programmes aimed at the development of drought tolerant varieties of Bambara groundnut.

Physiological Characters

The possibility that breeding programs may be reaching a point of limited progress because of the lack of genetic diversity has often been raised. However, there is also an often-expressed feeling that considerable genetic variability may exist in fundamental physiological processes. In this review, an attempt is made to examine whether there is evidence of genetic variability in quantitative physiological characters, and if so, whether such variability is likely to be useful to crop improvement programs. The results, presented from the literature and the author’s laboratory, indicate that physiological characters demonstrate considerable genotypic variability in expression. Moreover, in cases where genotype performance has been studied over a range of environments or where crossing studies have been carried out, physiological characters often have relatively high heritabilities. This suggests that, at least from a genetic standpoint, improvements in the expression of physiological processes may be possible. On the other hand, the problems of environmental sensitivity and its resultant error variability, combined with cumbersome methodology and complex physiological interactions, make it difficult to relate individual physiological characters to agronomic benefits, and make large genetic studies difficult. The exploitation of physiological diversity remains a major challenge to plant scientists.Key words: Genetic heritability, physiology of yield

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.

Cultivation of true shallot seeds has the potential to be developed in Indonesia because apart from being able to reduce the cost of providing seeds, it also has higher productivity than shallot from tubers. This study aims to determine the appearance of true shallot seed varieties that have high yield potential in the highlands of West Sumatra. The study used a randomized complete block design (RCBD) with 4 treatments of true shallot seed varieties, namely, Trisula, Bima, Lokananta, and Sanren, with 6 replications. The results showed that except for the age of harvest and the number of tubers per hill, the treatment of various varieties of true shallot seeds showed a significant effect on all observed variables. Lokananta variety has better growth component, yield component, and yields compared to other varieties (Trisula, Bima, and Sanren). Cultivation of true shallot seeds in the highlands gives lower yields than in the adapted area (lowland), except for the Trisula variety. Lokananta variety is recommended for use in the highlands of West Sumatra.

In southern Veracruz, Mexico, soil acidity is one of the main environmental factors that reduce the production yield of common bean. The objectives of this research were to identify outstanding opaque black bean breeding lines according to their level of adaptation to acid soils and high yield eff iciency with and without the addition of dolomite into the soil, as well as to determine which is the yield component that associates the most to a greater production of beans. During the Fall/Winter season of 2016-17 two trials were performed in Juan Rodríguez Clara, Veracruz, in a land with a soil of initial pH = 4.67. One trial was conducted under stress conditions by soil acidity and the other with 2.58 Mg ha-1 of dolomite, applied to the soil 27 d before sowing. Twelve black bean breeding lines were evaluated and compared to Negro Grijalva and Negro Comapa bean varieties. All beans were arranged in a randomized complete block design with three replicates. The variables measured were dry matter production without grain, weight of 100 seeds, number of pods per plant and grain yield. An analysis of variance of the quantif ied variables and the least signif icant difference (LSD, 0.05) tests for separation of means were performed. Negro Citlali/XRAV-187-3-1-8 showed the best adaptation to acid soil conditions in southern Veracruz, which obtained yields of 911.0 and 706.3 kg ha-1 with and without dolomite, respectively. These values were signif icantly higher than the commercial beans. This breeding line also showed the highest productive eff iciency, since it obtained the highest geometric mean (MGi) values (802.1) and a relative eff iciency index (IERi) of 2.00. Under both conditions of edaphic acidity, the number of pods per plant was the only plant trait that was positively related to seed yield (r = 0.91 ** and 0.87 **, with and without dolomite).

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 :

Background: Groundnut is an important oilseed crop in the India. The groundnut kernels serve as a rich source of edible oil (48-50%) and quality protein (25-28%). In crop improvement programme, availability of sufficient genetic variability is of immense importance. The knowledge of nature and magnitude of genetic variance controlling yield and yield components is a prerequisite for improvement of yield in any crop. Methods: The present investigation was undertaken to assess the genetic variability and character associations for pod yield and component characters in 45 genotypes of groundnut. The genotypes were raised in randomized complete block design with three replications during kharif 2019 at SKNAU, Jobner (Rajasthan). Result: The analysis of variance revealed significant differences among the genotypes for all the characters studied indicating presence of wide genetic variation for different characters. In the present investigation, high genetic advance coupled with high heritability and GCV was observed for biological yield per plant, 100-kernel weight, kernel yield per plant, dry pod yield per plant and pods per plant which indicated prevalence of additive gene action in their expression and these traits possessed high selective value. Kernel yield per plant, pods per plant and biological yield per plant exhibited significantly positive correlation with dry pod yield per plant both at genotypic and phenotypic levels, while shelling percentage at genotypic level only. Three characters viz., kernel yield per plant, pods per plant and biological yield per plant could be considered as direct selection parameters for yield improvement in groundnut because they exerted positive direct effect on dry pod yield per plant.

Background: Pigeon pea is considered an excellent and affordable source of plant-based protein, essential amino and fatty acids, fibers, minerals and vitamins with consistent source of income and employment to small and marginal farmers and thus holds premier position in the world agriculture. Shifts in rainfall patterns and seasons due to climatic change require the development of varieties with stable and high yield over a wide range of environmental conditions became major objective of crop improvement. Methods: The present study was carried out to ascertain the stable genotypes, environments discrimination and genotype by environment crossovers using different stable models by conducting Multi-location pigeon pea trial in five environments during Kharif, 2018 in Randomized Complete Block Design. Stability analysis for grain yield was performed by deploying the AMMI (Additive Main Effects and Multiplicative Interaction) model and GGE (Genotype and Genotype by Environment) biplot method. The pigeon pea genotype WRG-330 was found superior among all the genotypes over checks over locations, while, WRG-327 exhibited almost minimum interaction with the environments convincing the reliability of the performance. The test environments at Adilabad and Tandur were observed representative with better discriminating ability. Conclusion: It is concluded that there is no large difference between the AMMI and GGE biplot analyses in evaluation of experimental pigeon pea genotypes in different locations and both methods revealed similar results convincing that both methods can be used equally.
