Keragaman Morfologi Pertumbuhan 7 Klon dan 2 Varietas Tanaman Tebu (Saccharum officinarum L.) di PT Perkebunan Nusantara X Ploso Klaten-Kediri

Abstract

Sugarcane (Saccharum Officinarum L.) is the basic ingredient for making sugar. In Indonesia, in the last 5 years, sugar productivity only reached 5.2 tons/ha, very different from the productivity in 1935-1940, which averaged 17 tons/ha. This is because this Aat variety has not yet reached the desired productivity rate. The purpose of this study was to determine the diversity of growth of sugarcane (Saccharum officinarum L.) in clone SB01, clone SB03, clone SB04, clone SB11, clone SB12, clone SB19, clone SB20, variety PS862 and variety Bululawang. This research was carried out in the Djengkol garden, Ploso Klaten, Kediri. The tools used are sickle, cloth, tape measure, caliper, camera and stationery. The materials used are clone SB01, clone SB03, SB11, SB12, SB19, SB20, PS862 variety, Bululawang variety. Observations included growth variables (stem height, number of stems, number of leaves, stem diameter). Data analysis used ANOVA with a 5% F test. If there is a significant difference, proceed with the 5% DMRT test, correlation test, genetic diversity, heritability, genetic progress. Clone SB12 had an advantage in variable stem height of 395.83 (cm), number of stems 5.67 (stem), number of leaves 9.44 (strands), while clone SB01 had an advantage in stem diameter with the highest value of 31.99 (mm). Correlation relationship on sugarcane plant growth variables. The diversity of 7 clones and 2 varieties is heavily influenced by genetics and slightly influenced by the environment as shown by the KKG values in the medium-high category, the KF values in the low-high category, the Heritability (H2) medium-high category and the genetic progress (KG) category. rather high.
