Abstract
AbstrakUbi jalar memiliki keragaman genetik yang luas sehingga potensi genetiknya dapat dikembangkan lebih lanjut. Ubi jalar berdaging putih memiliki kandungan pati paling tinggi dibandingkan dengan warna yang lain. Tujuan dari penelitian ini adalah untuk mengetahui variasi karakter hasil dan komponen hasil klon ubi jalar berdaging putih. Percobaan dilakukan di tiga lokasi sentra produksi ubi jalar yakni Kabupaten Sumedang, Kabupaten Garut, dan Kabupaten Majalengka, Jawa Barat mulai bulan Desember 2019 hingga Desember 2020. Percobaan dilakukan dengan menguji 11 klon ubi jalar berdaging putih, yang terdiri atas 8 klon hasil persilangan dan 3 varietas cek menggunakan Rancangan Acak Kelompok dengan tiga ulangan. Karakter yang diamati terdiri atas karakter hasil dan komponen hasil. Kekerabatan klon ubi jalar berdaging putih dinilai berdasarkan keragaman genetik masing-masing karakter menggunakan analisis multivariat yang meliputi analisis klaster dan Principle Component Analysis. Hasil penelitian menunjukkan bahwa terdapat variasi karakter hasil dan komponen klon ubi jalar berdaging putih pada tiga lokasi tanam. Jarak genetik berdasarkan analisis klaster di tiga lokasi tanam secara berurutan adalah 2,20 – 5,95 Euclidean; 2,74 – 5,13 Euclidean; dan 2,26 – 5,61 Euclidean. Berdasarkan hasil analisis multivariate, klon ubi jalar berdaging putih pada ketiga lokasi memiliki variasi yang tinggi. Hasil tersebut berguna untuk menyeleksi klon ubi jalar berdaging putih dalam program perakitan varietas tanaman.Kata Kunci: Hasil ∙ Klaster ∙ Komponen hasil ∙ Multivariat ∙ Ubi jalar berdaging putih AbstractSweet potato has a wide genetic diversity so that its genetic potential can be developed further. White flesh sweet potato has the highest starch content compared to others. This study aimed to estimate the variation of yield and yield component traits of white fleshed sweet potato clones. The experiment was conducted at three regencies of sweet potato production center, i.e., Sumedang, Garut, and Majalengka, West Java, from December 2019 to December 2020. The experiment was carried out by testing 11 white-fleshed sweet potato clones consisting of 8 crossed clones and 3 check varieties by using Randomized Block Design (RBD) with three replications. Yield and yield component traits were observed. Estimation of relativity of white-fleshed sweet potato was evaluated based on the genetic diversity of each trait by using multivariate analysis included cluster and principal component analysis (PCA). The results showed that there were differences in genetic variability based on yield and yield component traits in three production centers. Genetic distance based on cluster analysis in three locations were 2.20-5.95 Euclidean; 2.74-5.13 Euclidean; and 2.26-5.61 Euclidean, respectively.Based on the results of multivariate analysis, white-fleshed sweet potato clones at the three locations had a high variation. These results are useful for selecting desired white-fleshed sweet potato clones in the plant breeding program.Keywords: Yield ∙ Cluster ∙ Yield component ∙ Multivariate ∙ White-fleshed sweet potato
