摘要

Jatropha curcas Linn, endemic to Tropical America is a drought-resistant plant which recently gained much importance in Asia and Africa as a biodiesel crop. Though it has wide cultivation in these areas the characterization and conservation of geneticresources remain poor. The present study focuses on surveying and collection of J. curcas germplasm in the study area. The study area falls under three different Agro-climatic zone of Karnataka viz., Southern Transition Zone (STZ), Hilly Zone (HZ) and Central Dry Zone (CDZ). All the taluks falling under STZ showed the incidence of J. curcas cultivation. In HZ except for Sringeri, all the taluks had an occurrence of J. curcas. The nonoccurrence of Jatropha plants in this area had been found mainly because of behavioral factor rather than environmental. In none of the taluks of CDZ which included entire Districts of Chitradurga and Kadur taluk of Chikkamagaluru district, J. curcas cultivation was found. The unawareness shown by farmers to the crop was found to be the reason for the non cultivation of Jatropha plants in these areas. Among the districts, in Shivamogga all the taluks had a prevalence of J. Curcas cultivation. In all the surveyed area J. curcas was grown as a hedge plant. The accessions belonging to drier regions of STZ had more fruit density per meter of live fence than the accessions of HZ with wet climate.

Curcas种质的测量和收集。该研究区落下了Karnataka Viz的三个不同农业气候区，南过渡区（STZ），丘陵区（HZ）和中央干燥区（CDZ）。落下的所有塔尔茨茨都展示了J.Curcas培养的发病率。在Hz除Srigeri除外，所有塔卢斯都发生了J. Curcas的发生。该地区的麻风树植物的非血流量主要是由于行为因素而不是环境。没有发现CDZ的CDZ中的所有地区，发现了J.Curcas培养的Chitradurga和Chikkamagaluru区的Kadur Taluk。农民对作物表现出的不明确是在这些地区非培养麻醉药植物的原因。在该地区，在Shivamogga的所有Taluks都患有J. Curcas培养的普遍存在。在所有被调查的区域J. Curcas被灌溉为树篱植物。属于STZ的干燥区的进入比Hz的湿气候的含量更多的活栅格的果实密度更多。
