“…Whereas plant height, leaf length and width, number of leaves per main shoot, number of days to maturity, length and girth of mother, primary and secondary rhizome, harvest index, dry recovery, oleoresin content and dry rhizome yield per plant showed low GCV and PCV indicating presence of low genetic variability for these parameters. Similar results have also been reported by Prajapati et al, (2014), Jalata et al, (2011), Yudhvir et al, (2003 and Jalgaonkar et al, (1990). Generally, the differences between phenotypic and genotypic coefficient of variability for all the corresponding characters was small indicating that these characters were less influenced by the environment.…”

“…Keragaman genetik luas menandakan keefektifan seleksi atau keberhasilan suatu kegiatan pemuliaan tanaman (Jalata et al, 2011). Semakin luas keragaman suatu karakter pada populasi maka semakin bervariasi sifat yang ada pada karakter yang mencerminkan pengendalian genetik pada populasi.…”

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.

Seed and seedling vigour is an aspect of seed quality which affects field establishment and performance. Low maize yields have been reported to be affected by several factors in which poor quality seed with low seed and seedling vigour. Information is scarce on seed and seedling vigour in maize inbred lines developed for tropical environments. Fifteen genotypes of tropical maize (Zea mays L.) inbred lines were evaluated to determine the level of differences in seed and seedling vigour traits, and extent of relationships among traits and their heritability. A substantial amount of genetic variability was found, which suggested that most of the traits under study could be improved through selection and utilized in breeding programs. Positive and significant interrelationship among seed germination and seedling traits and a positive correlation between seed germination and seed vigour and field emergence showed that these could be given due consideration in crop improvement for seed and seedling vigour. High genotypic coefficient of variation, heritability and genetic advance were obtained for seed germination, seed emergence, shoot length and seedling vigour index I and II, revealing the possibility of improvement in these characters through direct selection. The principal component analysis (PCA) identified seed emergence, shoot length, seedling vigour index I and II and tetrazolium vigour as characters that contributed greatly to variation in seed vigour in the maize inbred lines. Cluster analysis partitioned the genotypes into two groups, with group I consisting of seven genotypes and group II comprised the other eight genotypes, which suggested that hybridization between the two groups could lead to high level of heterosis. Genotype V 5 had superior seedling vigour traits compared to other genotypes. Seedling emergence, shoot length, seedling vigour index I, seedling vigour index II and tetrazolium vigour are effective characters for good seedling vigour traits in maize inbred lines investigated.
