Morphological Response Of Wheat Genotypes At Different Altitudes In Karo Highland Sumatera Utara

Abstract Grain growth is strongly influenced by climate where the plants grow. One of the parameters that affect the climate of the plant growth is temperature. Air temperature difference at one place to place depending on the altitude and latitude location. Climate change and the limitations of specific wheat varieties into one obstacle wheat development in the country. Then carried out research that aims to get the wheat genotypes corresponding to climatic conditions especially temperature of a specific location through morphological response every kind of wheat used. The research was conducted in two Karo highland locations namely Berastagi 1400 meters above the sea level and Tiga Panah 1100 meters above the sea level during the rainy season by using the twelve wheat varieties are two varieties of wheat namely SelayarK and Dewata L and ten genotypes A OASISSKAUZ4BCN B HP1744 C LAJ33022MO88 D RABE2MO88 E H-21 F G-21 G G-18 H MENEMEN I BASRIBEY J ALIBEY. This research aimed to obtain the appropriate type of wheat planted in each location based on morphological characters such as plant height number of grainspike and grain weightspike. The design used is non factorial randomized block design. The result showed significant difference for all types of wheat on plant height number of grainspike and grain weightspike.
