Soil moisture deficit is the major constraint for sesame crop production during its main
rainfed and summer cultivation seasons. In summer cultivation, the crop frequently gets
exposed to soil moisture deficit at various crop growth stages. Therefore, it is essential to identify
the traits along with promising genotypes adapted to soil moisture deficit. A set of 35 sesame
genotypes with checks was used to quantify the variation in morpho-physiological, yield,
and quality traits under irrigated (WW) and deficit soil moisture stress (WS) conditions in the
summer seasons of 2021 and 2022. The analysis of variance revealed the presence of high variability
among the genotypes for various measured traits. The mean performance indicated
that WS negatively affects the growth, development, yield and quality traits. Moreover, the
correlation, path analysis and D2 analysis studies suggested that the traits, viz. leaf area
(LA), total dry matter (TDM), canopy temperature (CT), number of branches per plant
(NBP) and number of seeds per capsule (NSC) were significantly associated with seed yield
under both the conditions. Quality traits like palmitic acid and oleic acid correlated positively
with seed yield, particularly under WS. Furthermore, the genotypes with lower canopy temperatures
were found to be better seed yielders under WS. In addition, mean performance and
cluster analysis suggested that the genotypes: IC- 205776, JSCDT-112, JCSDT-26, IC-205610,
and IC-204300, secured higher seed yield along with superior agronomical traits and net
photosynthetic rate. These selected genotypes were most promising and could be used in
future sesame crop improvement programmes.
