Sugarcane is one of strategic and important food commodities in Indonesia because it is the main source of sugar producers. Domestic sugar production in 2015 only reached 2.5 million tons, while its needs are 5.6 million tons which resulting in a shortage of 3.1 million tons to be met from import. The production in 2016 just reached 2.5 million tons causing the shortages that must be filled by import as much as 3.1 million tons. The Ministry of Agriculture has a program for sugar

The discrepancy between production levels at this time with the target in 2014 still quite wide. The target accession can be reached by intensification and land extension or expansion. The availability of land development with the availability of adequate water has to face obstacles competing with rice plant as the main staple food. In 2007 more than 60% sugar cane crop was in dry land (Hadisaputro, et al., 2008). The expansion of dry land still has an opportunity to be developed in various ways such as the availability of sugar cane varieties with drought resistant. The research objectives are to accomplish the drought resistant selection in the field to the result of crossbreeding clones in 2014 (MLG-14). The activities implemented in KP. Karangploso, Malang, started on January until December 2016. The research materials are 51 crop clones of two stage selection which 7 varieties are PSDK, PSJT 941, PS 881, PSJK, VMC 76-16, GLAGAH, ERIANTHUS, CENING, BL, and PS 881 as a control. Using a randomized block design with three replication were planted in plots consisting of three arc along the 5 m. The PKP range (from center to center of arc) are 100 cm length. The range between replications is 2.5 – 3 cm length. The seeds form is a one eye mule (bud set). Furthermore, after 1.5 month old, the seeds were selected based on its uniformly conditions and then planted in the segment with the range of 50 cm length between plants, so the [...]
