Abstract

The main problems investigated in these research are 1) the developing of local peanut variety from west Sumba through breeding with multigamma radiation method (nuclear) and carefully selection on two varieties of peanut, i.e erect peanut and creep peanut by multiculture principle, in order to obtain the primer seed of local peanut variety that can increase production, 2) developing of primer seed of local yellow corn, in order to tolerant to abiotic and biotic conditions. The main method of research is application of multigamma radiation that supported by other methods comprised of observation/survey, sampling, multiculture, analysis, comparison, and interpretation.

The results of research are two primer varieties of local peanut seed from East Sumba with principle multiculture by multigamma radiation and carefully selection, and the primer seed of sweet local corn that tolerant to abiotic and biotic conditions, in order that production results of peanut’s farmer and local corn in East Sumba specially and NNT generally, can significantly optimally increase, to support the stamina and safety of National food. The average production is obtained 5.7 ton/ha and 4.5 ton/ha for erect peanut, or the average production increase 43.86% for creep peanut and 42.22% for erect peanut.

On the second planting (first cleansing), the research on the second year, obtained the increase of average production about 45.84% (percent) of dried pod for erect peanut and 46.67% (percent) of dry pod for creep peanut. The increase of production potential on the second planting, the research on the second year in succession is 52.29% (percent) dried pod dried pod for erect peanut, and 52.22% (percent) dried pod for creep peanut. The increase average of production on the second year of research is 40.25% (percent) dried pod for erect peanut, and 40.42% (percent) dried pod for creep peanut. The increase average of production potential 48.84% (percent) dry pod for erect peanut, and 49.95% (percent) dried pod for creep peanut.
