“…The results of Prayudha et al ( 2019) obtained the Predominant vine color, the type of lobe, the lobes number, the leaf lobes shape, the type of plant, the size and length of the petiole, tubers per plant number, the tuber length, the tuber diameter, the internodes diameter, and internodes length have major contributions to the diversity of 11 purple sweet potato genotypes. Research by Lestari & Julianto (2020) showed that number of tubers, tuber weight, tuber dry matter, biomass dry matter, and harvest index were the characteristics that contributed greatly to the diversity of the 13 sweet potato genotypes.…”

Information about the morphological and genetic characteristics of sweet potato (Ipomoea batatas) is important in the variety development program. This experiment aimed to determine the diversity and genetic relationship of sweet potato accessions from NTT based on morphological character data. The research was carried out at Kendalpayak Research Station, Malang, East Java from April - September 2019. The materials used were seventy-one sweet potato germplasm from the ILETRI collection (collected from NTT). Each accession was planted on a 1 m × 5 m plot size, with a spacing of 100 × 20 cm (single row). Fertilization was carried out using a dose of “100 kg urea + 100 kg SP36 + 200 kg KCl ha-1”. The observed characters were the vines length, growth type, internode length, leaf length, leaf width, leaf size, leaf bone color, leaf shape, leaf characteristics, lobes number, lobe shape, mature leaf color, shoot color, pigmentation of petiole, young stems pigmentation (dominant and secondary color), young leaves feathers, tuber skin color, tuber flesh color, weight of canopy, number of tubers perplot, weight of tubers perplot, number and weight of tubers perplot. Cluster analysis was carried out using the Minitab 17 program. There was morphological diversity in seventy-one accessions of sweet potato germplasm from NTT. Principal component analysis resulted in seven main components with the proportion of diversity 76.3%. cluster analysis, seventy-one accessions of sweet potato germplasm were divided into fifteen accession groups on the basis of 80% degree. Characteristics of shoot color, mature leaf color, leaf size, petiole pigmentation, and leaf bone color contributed greatly to the total diversity.

“…Tiga belas genotipe yang dianalisis mempunyai keragaman genetik dan keragaman fenotipe yang luas terutama pada parameter jumlah umbi, bobot kering umbi, bobot kering brangkasan dan kadar betakaroten (Lestari & Julianto 2020). Tingginya nilai keragaman genetik dan keragaman fenotipe menjadikan kegiatan seleksi dalam proses pemuliaan tanaman untuk menghasikan varietas unggul akan berjalan lebih efektif dan efisien.…”

CORRELATION AND PATH ANALYSES FOR DETERMINING THE SELECTION CRITERIA OF HIGH YIELDING SWEET POTATO (Ipomoea batatas (L.) Lam.)]. Sweet potatoes can be used as an alternative source of healthy carbohydrates. The productivity of sweet potato is relatively low, which was 13,51 tons/ha. To breed the potato plants one of the solutions to develop superior varieties. The success of plant breeding is determined by the success of the selection activity, one of which is determined by the selection characters used. Correlation and path analysis are used to study the closeness of the quantitative variables as the basis for a more efficient selection program. The purpose of the research was to determine the selection character of sweet potato and to study the correlation pattern between the observed characters based on the correlation coefficient value along with the direct and indirect effect. The research was carried out on dry land with Inceptisol soil type, at an altitude of 350 m above the sea level and arrange a randomized block design with three replications. The material used thirteen sweet potato genotypes. The results of the correlation analysis showed that the tuber yield had a very strong and positive correlation to the number of plants (r = 0.706), the fresh weight of tuber (r = 0.816), and dry weight of tuber (r = 0.898), while the tuber number had a moderate positive correlation. (r = 0.605). Several variables also showed a negative relationship, including stover fresh weight, % of tuber dry weight, dry weight of stover, and dry weight of biomass. Based on the correlation and path analysis, the variable of tuber dry weight can be used as an effective and efficient selection character in order to produce the high yield of sweet potatoes.
