“…Nilai duga heritabilitas suatu karakter perlu diketahui untuk menduga kemajuan seleksi dan juga mengetahui bahwa suatu karakter tersebut lebih dipengaruhi oleh faktor genetik atau lingkungan (Lestari et al, 2015). Nilai duga heritabilitas ini bermanfaat dalam melakukan proses seleksi (Syukur et al, 2012).…”

Winged bean (Psophocarpus tetragonolobus (L.) DC) is known as tropical soybean with high nutritional content. Lack of information on the variance components and heritability of winged bean breeding is one of the reasons for the lack of winged bean breeding programs in Indonesia. This reseach aimed to obtain information on variance components, heritability and relationship between winged bean traits. The experiment was conducted in three environments, from January 2019 to June 2020. Two environments located in Bogor and one in Palembang. Eleven genotypes of winged bean were tested and 11 traits were observed. The result showed that flowering time and seed number per pod performed wide genetic variability. High heritability was observed on seed number per pod (89.48%), flowering time (83.32%), young pods length (70.97%), and weight of 100 seeds (68.63%). The results of correlation analysis and path analysis showed that young pod productivity (1.07), seed weight per plot (0.81), flowering time (0.29), young pod length (0.17), young pod width (0.12), seed weight per plant (0.09), and 100 seeds weight (0.01) had a positive direct effect on wing bean productivity. Flowering time, seed number per pod, seed weight per plant are suitable characters for selection criteria for breeding high productivity winged bean. Keywords: correlation, genetic variability, path analysis

“…Nilai heritabilitas tinggi menunjukkan bahwa karakter tersebut lebih dipengaruhi oleh faktor genetik dibandingkan faktor lingkungan sehingga karakter yang memiliki nilai heritabilitas tinggi menggambarkan bahwa karakter tersebut mudah diwariskan (Widyawati et al, 2014). Hal yang sama juga seperti dilaporkan oleh Lestari et al (2006) dan Zen (1995) karakter yang memiliki nilai duga heritabilitas tinggi maka seleksi bisa dilakukan pada generasi awal karena karakter dari suatu genotipe mudah diwariskan ke keturunannya, sedangkan jika nilai duga heritabilitas rendah maka seleksi dilakukan pada generasi lanjut.…”

“…Beberapa penelitian pada cabai menunjukkan bahwa nilai duga heritabilitas arti luas yang tinggi pada karakter umur berbunga (Lestari et al, 2006), bobot buah per tanaman, jumlah buah per tanaman, panjang buah (Syukur et al, 2010); bobot per buah, panjang buah, diameter buah, tebal daging buah, jumlah buah per tanaman, bobot buah per tanaman, umur panen, dan umur berbunga (Widyawati, 2014); umur berbunga, umur panen (Satriawan et al, 2017); umur berbunga (Hastuti et al, 2016); umur panen (Arif et al, 2012); panjang buah (Dewi et al, 2016); bobot per buah, diameter buah, bobot buah per tanaman, umur panen, jumlah buah per tanaman (Qosim et al, 2013); jumlah buah per tanaman, panjang buah, bobot buah per tanaman (Meena et al, 2016); jumlah buah per tanaman, bobot buah per tanaman, panjang buah dan bobot per buah (Farhad et al, 2008;Chakrabarty dan Islam, 2017). Sementara nilai heritabilitas karakter diameter buah (DB) termasuk dalam kategori sedang.…”

Assembling plant variety requires genetic information about the concerned traits. One way to obtain genetic information is through estimating genetic component and heritability. This experiment aims to obtain information varians component variety and heritability in 2 populations of bird pepper. Each population P1, P2, and F1 was planted with 40 plants, BCP1 and BCP 2 was planted with 100 plants and F2 was planted with 300 plants. Results in IPB C285 x IPB C290 population show the heritability broad sense with height category for all characters except fruit diameter. The number fruits per plant and fruit thickness has the highest category for heritability narrow sense. Results in IPB C321 x IPB C290 population heretability broad sense with hight category for all characters except weight per fruit. Fruit length was included in the high category for narrow sense heritability. The ratio of additive varians was greater than non additive varians in IPB C285 x IPB C290 population for number fruit per plant, weight per fruit, fruit length, fruit diameter, fruit thickness and harvest time while in IPB C321 x IPB C290 population number fruit per plant, fruit length, fruit thickness and fruit diameter. The selection method that can be used in both populations was the pedigree method so that selection activities can be carried out in early generation. The population IPB C285 x IPB C290 pedigree selection method was carried out on number fruits per plant and weight per fruit whereas in IPB C321 x IPB C290 population, pedigree selection method was carried out on fruit length.

“…Keragaman genetik dapat diperoleh melalui berbagai cara antara lain introduksi, mutasi, hibridisasi, ploidisasi dan rekayasa genetika (bioteknologi). Beberapa penelitian tentang keragaman genetik, heritabilitas dan pewarisan pada cabai telah dilakukan oleh beberapa peneliti seperti Sreelathakumary dan Rajamony (2004), Lestari et al (2006), Hilmayanti et al (2006, Smitha and Basvaraja (2007), Marame et al (2008), Ajjapplavara dan Channagoudra (2009), Sharma et al (2010) dan Ganefianti et al (2014).…”

“…Hal ini sesuai dengan hasil penelitian Ramadhani et al (2013) menyatakan bahwa nilai duga heritabilitas dan keragaman genetik yang diamati memiliki kriteria yang tinggi dan luas pada peubah diameter buah dan panjang buah. Di dukung hasil penelitian Syukur et al (2011) dan Lestari et al (2006) peubah diameter buah dan panjang buah memiliki nilai duga heritabilitas yang tinggi. Saputra et al (2013) mengemukakan bahwa berdasarkan pandangan pemuliaan tanaman, untuk mendapatkan varietas cabai yang unggul, pemilihan genotipe yang memiliki panjang buah, tebal daging buah, diameter buah dan bobot perbuah merupakan upaya yang dapat dilakukan untuk meningkatkan produksi cabai.…”

Chili development in Indonesia faces several constraints, mainly low yields and disease incidents. The improvement of chili traits through breeding programs requires information of genetic diversity, heritability, genetic advance and gene role. A study was conducted to assess the values of variability and heritability of qualitative and quantitative traits of 20 genotypes of chilli plants. The study was conducted in May-September 2015 on Experimental Field of Faculty of Agriculture, the University of Bengkulu. The 20 chili genotypes were arranged factorially in a Randomized Complete Block Design, with three replications. The results showed that the qualitative characters that have broad sense of variability and heritability were plant height, days to flower, time to harvest, fruit length, fruit diameter, fruit weight, and weight of fruit per plant, indicating that a selection can be done on those variables. Variability on qualitative characters was found on the position of the flower stalk (3 kinds), corolla color (4 kinds), color of corolla holder (3 kinds), corolla shapes (2 kinds), anther colors (4 kinds), pistil colors (3 kinds), colors of young fruit and ripe fruit (3 kinds), and fruit position (3 kinds).
