Sesame Breeding for High Yield: Preliminry Yield Trial from Collection Sets Year 2000 nd 2001

Abstract

 This preliminary yield trial was aimed for a new high yielding variety of sesame in the sesame breeding project for high yielding, and it was started in 2000.  Twenty nine sesame lines selected from collection and evaluation trial in 2001 were grown together with four recommended varieties, namely, Ubon Ratchathani 1 (red), Mahasarakham 60 (white), Roi Et 1 (white) and Nakhon Sawan (black) as checks, in the early and late rainy seasons for the preliminary yield trial in  2002 at Ubon Ratchathani field Crops Reserch Centre.  In the early rainy season, twelve lines were selected with the range of yield per plot between 236 and 3.78 g. number of capsule per plant between 24 and 60 capsultes.  Seed coulour of six of them were white, two were black and four were brownish gray.  In the late rainy season, twelve lines were also selected withthe rnge of yield per plot between 442 and 546 g, yield per plant between 2.9 and 6.6 g, 1,000 seed weight between 2.60 and 3.40 g, number of capsule per plant between 12 and 35 capsules.  The dat of sesame grown in two seasons were analyzed and compared by using a database programme including pictures of their canopy and seed to heip for decision making.  Fifteen sesame lines were then selected by their good performnce of yield and yield components in both seasons and for the advanced standard yield trials in 2003.
