O trabalho teve por objetivo verificar diferenças entre rendimento do concentrado proteico e proteína bruta da folha da mandioca (Manihot esculenta Crantz), obtidos a partir de três variedades comerciais: branca, cascuda e vermelha. As manivas foram plantadas seguindo o delineamento experimental inteiramente casualizado com três repetições. Nas comparações entre as variedades, considerou coletas escalonadas pós-plantio, realizadas aos 12, 14 e 16 meses. O concentrado proteico foi obtido a partir da farinha das folhas inteiras e submetido ao método de termo - coagulação ácido e a proteína bruta pelo método padrão AOAC. Os dados foram submetidos a análise de variância e comparados pelo teste de Tukey - 5% de probabilidade. Os resultados não indicaram diferença significativa entre as médias obtidas para rendimento de concentrado proteico. Para a variável porcentagem de proteína bruta a variedade Branca foi a que apresentou maior valor, com média de 46,25%, seguida pela Cascuda e Vermelha, 44,52% e 37,30%, sucessivamente. Conclui-se que outros estudos devem avaliar condições que possam influenciar no teor de proteína foliar, como clima e solo, e, avaliar os níveis de ácido cianídrico de cada variedade, indicando qual das três é a melhor para a extração do concentrado proteico das folhas. Palavras chaves: Manihot esculenta Crantz, variedades comerciais, concentrado proteico, proteína bruta. ABSTRACT: The study aimed to assess the differences between income protein concentrate, crude protein of cassava leaf (Manihot esculenta Crantz), obtained from three commercial varieties: white, red and cascuda. The cuttings were planted following the completely randomized design with three replications. Comparisons between the varieties considered after planting staggered collections, held on 12, 14 and 16 months. The protein concentrate was obtained from flour of whole sheets and subjected to the term method - acid coagulation and crude protein by AOAC standard method. The data were submitted to ANOVA and Tukey test - 5% probability. The results indicated no significant difference between the mean values obtained for protein concentrate income. For the variable percentage of crude protein White variety showed the highest, with an average of 46.25%, followed by cascuda and Red, 44.52% and 37.30%, successively. We conclude that further studies should evaluate conditions that may affect the leaf protein content, such as climate and soil, and evaluate the hydrocyanic acid levels of each variety, indicating which of the three is the best for the extraction of protein concentrate from leaves Key words: Manihot esculenta Crantz, commercial varieties, protein concentrate, crude protein.

Indonesia memiliki kekayaan plasma nutfah ubi kayu yang tersebar di seluruh wilayah Indonesia. Ubi kayu mengandung karbohidrat tinggi dan berperan dalam diversifikasi pangan. Tujuan dari penelitian ini adalah menyeleksi 80 varietas ubi kayu budidaya lokal asal berbagai wilayah di Indonesia yang berpotensi hasil tinggi. Penelitian ini menggunakan 80 aksesi ubi kayu dari seluruh pulau-pulau besar di Indonesia yang disusun dalam rancangan Augmented dengan 3 tanaman kontrol per baris. Penelitian dilakukan dari Juli 2013-November 2014. Hasil penelitian menunjukkan bahwa keragaman genetik dan fenotipik yang luas pada ubi kayu asal Indonesia berdasarkan karakter umbi. Potensi genetik berdasarkan karakter hasil dan komponen hasil terkategorikan tinggi dengan nilai heritabilitas 0,59-0,75. Uji lanjut LSI (Least Significant Increase) menyeleksi aksesi yang memiliki daya hasil tinggi pada karakter umbi diantaranya karakter jumlah ubi/tanaman pada aksesi 563, 570, dan 599. Karakter bobot ubi/tanaman pada aksesi 507,563, 598, dan 541. Karakter bobot/ubi pada aksesi aksesi 534,528 dan 541. Karakter bobot ubi/plot pada aksesi 629. Karakter potensi hasil pada aksesi 629. Hal ini dapat memberikan informasi mengenai diversitas genetik aksesi-aksesi ubi kayu lokal Indonesia sehingga dapat dievaluasi untuk didapatkan hasil tinggi ubi kayu untuk diversifikasi pangan.
