India is thought to be one of the most important places for the genetic diversity of S. indicum. The itinerary and the trip route are shown in Table 1 and Fig. 1, respectively. We collected a total of 185 seed samples, of which 163 were those of S. indicum and its relatives (Table 2). The collection trip was started from South India to North India. Morphological variation of S. indicum was rather small in the Deccan Plateau of South India so far as observed. The so-called tropical type, which was characterized by tri-lobed leaves on the lower nodes, a single capsule per leaf axis, two carpels per capsule and branching habit on higher nodes, was commonly grown there. Plants with uni-lobed leaves or those having four carpels per capsule were rarely found admixed in the fields. The seed color varied as black, dark brown, brownish white and white. Local farmers in some villages near Raichur, Karnataka informed us that they grew two distinct types of black seeded sesame : a usual type and a bitter type. They used the bitter sesame for a medicinal purpose as well as for oil extraction. In North India, S. indicum plants having different morphological characteristics were usually found mixed even in a small field. We observed alternately or oppositely fruited plants having one or three capsules per axis, and those of branching or non-branching types. A few plants which had semi-wild or weedy traits were also collected in a village near Jhansi, Uttar Pradesh. They had small fruits and the upper carpel of each fruit was easily dehiscing. It became clear through the interviews to the local farmers that S. indicum was widely used as a material for various food preparations rather than an oil source. For example, it is cooked for sweets, stuffing, topping, seasoning and so on. As an oil crop, sesame has been replaced by sunflower and soybean, since its productivity is lower. Local cultivars of this crop are, however, still grown often on a small scale, because of its importance in the traditional food habit in India.}, pages = {45--66}, title = {インド国におけるゴマ遺伝資源の探索収集}, volume = {9}, year = {1993}, yomi = {コメイチ, ミチタカ and カワセ, マコト} }
