UFSM XIKA FW: sugarcane cultivar for southern Brazil

Resumo

In Brazil, due to the different soil and climatic conditions of the sugarcane producing regions, a strategy of creating small breeding programs for the crop is being used. Since 2008, the sugarcane breeding program of the Federal University of Santa Maria (UFSM), Campus Frederico Westphalen, works with the objective of developing new sugarcane cultivars, more adapted and productive to the meteorological conditions of the southern region of Brazil. UFSM XIKA FW is a cultivar developed at the Laboratories of Agroclimatology and Genetic Breeding and Plant Production of the Federal University of Santa Maria, Frederico Westphalen Campus. Was the first cultivar of sugarcane protected in the Ministry of Livestock Agriculture and Supply obtained from induction of mutation. The genotype used for mutation induction was the cultivar IAC 87-3396, due to its good performance characteristics in the southern region. Mutation was induced in 2011, by immersing individual buds in solution of the chemical mutagenic agent Methyl Methane Sulfonate (MMS). The best genotypes were selected and tested in trials in plant cane 2013 and 2018 and in ratoon cane in 2014 and 2015. The new cultivar has higher potential of sugar production and the yield was higher in the mean of the 4 years, exceeding the control in 8,2 t ha^-1, demonstrating a high yield potential. For its performing, it is being evaluated in tests of Value for Cultivation and Use (VCU).
