Keragaman genetik dan heritabilitas karakter komponen hasil dan hasil ciplukan (Physalis sp.)

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.

The focus of wheat research in Indonesia is to obtained new potential wheat lines that are adapted to low-mid elevation and heat tolerant. This study was aimed to obtain information on the effect of interaction of season x line x location and genetic variability of wheat lines in tropical agroecosystem. This study was conducted at the Seameo- Biotrop (<400 masl) and Indonesian Ornamental Crops Research Institute-Cipanas (>1,000 masl) experimental field for two seasons. The results showed that there was an effect of interaction of season x line x location on plant height, days to flowering, number of spikelet and floret, seed/head weight, rate of grain filling, yield, flag leaf width, stomata density, chlorophyll b, and leaf greenness. Meanwhile several characters were only influenced by the interaction of line x location, they were yield component characters, ie. empty floret percentage, number of seed/ head, 1,000 seed weight, number of head/m2 and seed/plant weight. Seven characters were not influenced by interaction of neither season x line x environment nor line x location, they were number of productive tillers, head length, number of seed/head, chlorophyll a, ratio of chlorophyll a/b, total chlorophyll, and leaf thickness. The characters that have high heritability and wide genetic variability for the two analysis models were the number of spikelet.

Coefficient Of Genetic Variation

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.

This study aimed to estimate genetic and phenotypic parameters and provide knowledge for breeding programs aiming at the selection of the main characters of assessment in soybeans. The experiment was installed in Sabia farm, located at ‘Serra das Laranjeiras” , in the municipality of Currais, Piaui, Brazil, during the 2011/2012 crop year using a randomized block design with 27 genotypes and three repetitions. The evaluated variables were: height at flowering (APF), height at maturity (APM), pod insertion height (AIV), grain yield (PG), number of nodes (NN) and number of pods (NV). The obtained heritability coefficients were from medium to high, for all evaluated characters, ranging from 0.53 to 0.94, for grain yield and plant height at flowering, respectively. These high heritability were confirmed by the high degree of genetic variation and the CVg/CVe ratio, indicating a high prospect of success for the phenotypic selection. The higher positive genetic correlations and the significant (P <0.01) were observed between grain yield and the variables number of nodes (0.807**) and number of pods (0.781**), indicating that the selection of plants with higher number of nodes and pods could result in more productive plants. The Williams-based index presented the highest percentage of gain with the selection offor the grain yield (21.84%) variable.

ABSTRACT Due to the high genetic variability found in sweet potato and a low number of cultivars available on the market, there are opportunities for necessary improvements in crop breeding programs. The selection indexes are a favorable strategy to achieve higher yields through genetic gains obtained with the future population. Thus, the objective was to evaluate the selection gain of agronomic characters from sweet potato accessions for root production and dual-aptitude. 95 accessions and two commercial cultivars (Braslandia Branca and Brazlândia Roxa) were evaluated. A randomized block design with three replications of ten plants per plot was used. The index proposed by Mulamba & Mock was used to select superior individuals. The evaluated population showed high genetic variability providing considerable selection gains, being recommended some clones for tests of value for cultivation and use. The VR13-61 accession was the most recommended for root production and VR13-11 and VR13-22 for dual-aptitude.
