Abstract:

An investigation was carried out to study the genetic variability and effect of environmental factors on oil content and fatty acid composition in two different seasons using 33 sunflower accessions. Significant variability for physiological, morphological, yield and yield attributing characters and also for oil content and fatty acid composition due to the effect of seasons, temperature and genetic makeup of genotypes were observed. Plants grown in kharif had 36.4 per cent more grain yield compared to rabi. Hybrids yielded more followed by inbreds and seed setting was less in RHA lines. Higher TDM was recorded with hybrids compared to CMS lines, RHA-lines and inbreds. Out of 33, 22 genotypes recorded higher oil percentage in rabi than in kharif. Oil content was less in most of the genotypes during rabi/summer due to physiological maturity of genotypes coincided with higher temperature and bright sunshine hours. Accumulation of maximum grain oil content was found in early matured genotypes. Depending on their consistent performance, genotypes can be selected for heterosis breeding to develop good fatty acid containing hybrids combined with high seed yield.
