The present study was carried out to assess the genetic
diversity in durum wheat genotypes under rainfed and
irrigation conditions in dryland agricultural research
institute (DARI) during the 2011-13 cropping seasons.
Results of multivariate analysis revealed that the number
of fertile spikes, number of grain per spike and days to
physiological maturity were highly effective on grain yield
under both conditions. A clustering analysis based on
both agro-morphological and molecular characters
indicated a good level of genetic diversity. Low correlation
was found between the diversity obtained by markers
and the agro-morphological traits. The Sardari genotype
had the maximum genetic distance from other
genotypes in the agro-morphological analysis. The
average polymorphic percentage for inter simple
sequence repeat (ISSR) primers was 83.46%. Primers, IS6,
IS25, IS14 and IS27 had the highest resolving power.
Maximum genetic distance among the genotypes with
the Jaccard similarity (0.314) was between G6 (19EM84859)
and G17 (19E-M142070). The findings would help
selecting suitable genotypes for enhancing the yield of
durum wheat.
