Abstract


Drought problem is one of limiting factors in agriculture development in
Indonesia. One of the well-known drought prone areas is found in Gunung Kidul
Region of Yogyakarta Province. In this hilly District, agriculture and livestock are
mainly the basic income for the people living there. The problem is that annual dry
season goes quite long namely for about 6 months, starting from May up to October.
During dry season most arable land becomes barren, and farmers attempt to import
corn leaves (plant stovers) in a big amount from other Regions or Provinces in order
to suffice their cattle feeds. Sorghum plant (Sorghum bicolor) is thought of having
high tolerance to drought Breeding sorghum for improved its yield in drought prone
areas can be of importance for animal husbandry in the region. Research on sorghum breeding by using mutation techniques has been conducted at BATAN. Induction of mutation was made by gamma irradiation emitted from Cobalt~6O source. The breeding objective was to improve sorghum production (seeds and stovers) in drought prone areas to be used as alternative animal feeds especially during dry swson. Some promising mutant lines of sorghum had been identified and registered These lines were tested against drought in Gunung Kidul region in 2001. Research collaboration with national and intemational institutions was made to support the development of sorghum germplasrn collection and mutant stock repository.
