ABSTRACT







	A drought condition at several regions recently in Indonesia is absolutely affected by the climate change. Regarding to national wheat consumption for food industry, Indonesia reach around 5,\mbox{35\,m} ton during  2012--2014. (USDA, 2014). Thus, national industry on floor regularly imported 7 ton per year of wheat as the row material. Regarding to plant growth and development that plant require the optimum environmental factor, such as water and temperature. It is known well that water is an essential component in the process metabolism of plants. Based on the recent study showing the high temperature and drought can promote increasing the plant transpiration and the decreasing of yield significantly, particular on wheat plantation. We investigated on several lines of wheat the effect level of drought as the model of climate during the dry season that influence significantly on drop of yield. Those indicator absolutely due to the growth of root was inhibited by level of drought especially on dry season. The level of drought caused the climate change influence on several growth parameters such as the number of leaves, number and length of roots, number of spikes, number of seed on spike, seeds production on each spike and total yield. We found the special introduced"=variety of wheat (SO) had the significant tolerant to drought and able to maintain the SRL (specific root length) and proline contents to face the drought condition. The proline as amino acid shows increased extremely effected the drought and the root length reduces dramatically, then those plant condition influence the plant growth and seed production. However, the SO selected"=variety had the stability on yield production compare to other varieties, since it able maintain the contain of proline and ratio of root length in plant.  The results indicated that SO is  a selected variety of wheat in Indonesia for some regions recently which had the character able to maintain the seed production at approximately \unitfrac[3.5]{ton}{ha} particularly on long dry season.
