Determining the interaction of G �? S and assessment of characters association for some morphological traits and seed yield


Tamal Chakraborty and Amal Kumar

The experiment was carried out at Gedarif Agricultural Research Station Sudan, during the rainy seasons 08/09 and 09/2010, to estimate the genotype x season interaction and to asses the characters association for seven sesame genotypes. A randomized complete block design with four replicates was used. The parameters were days to 50% flowering, days to maturity, plant height, number of capsules/plant, seed yield/plant (g) and seed yield/ ha (kg). All characters showed highly significant differences at the genotypic level, the days to 50% flowering and to maturity revealed significant differences at both seasons and the G × S interaction levels, whereas the seed yield / plant showed significant differences at the season level .Gedaref -1 out yielded the overall mean by 26.15%. In both seasons, the seed yield (kg/ha) was significantly and positively correlated with days to maturity, plant height, number of capsule/plant, seed yield/plant at both the genotypic and the phenotypic levels. From this study: to improve seed yield in sesame, emphasis should be made on selection tallest plants with more capsules and high yielder genotypes.
