Study of genetic diversity in safflower genotypes using agro-morphological traits and RAPD markers

Abstract

This research was conducted to study the genetic diversity in safflower (Carthamus tinctorius L.) using agro-morphological traits and RAPD markers. Sixteen selected lines derived from landraces growing in various agro-climatic regions of Iran along with four exotic genotypes were evaluated in a randomized complete block design with three replications under field conditions. Days to emergence, days to initial flowering, days to flowering, days to maturity, plant height, branches per plant, capitula per plant, seeds per capitulum, 1,000-seed weight, seed yield per plant, seed yield, and reaction to powdery mildew (Leveillula taurica Arnaud) were evaluated in this study.

EVALUATION AND POOLING OF SAFFLOWER (Carthamus tinctorius L.) ACCESSIONS FROM DIFFERENT WORLD ORIGINS USING AGRO-MORPHOLOGICAL TRAITS.

“…However, several genotypes were more productive than the check variety which produced 1.3 t/ha. Narrower variation ranges were reported in previous studies, from 1.5 to 2.7 t/ha (Panahiet al, 2013) and from 1.1 to 2.2 t/ha (Amini et al, 2007).…”

“…Res. 5(7), 926-934 927 of the world (Amini et al, 2007). In comparison with other oilseed crops, safflower is characterized by high adaptation ability in regions where winter months are cool and summer months are arid (Erbas et al, 2016).…”

Proximate composition, amino acid profile, carbohydrate and mineral content of seed meals from four safflower (Carthamus tinctoriusL.) varieties grown in north-eastern Morocco

“…The weight of 1000-seed varies between 15-104 g with a hull percentage that varies between 18-59% of seed weight (Smith, 1996;Bowles et al, 2010). It has been emphasized in several studies that these characteristics are influenced by genetic variation (Smith, 1996;Amini et al, 2008;Ben Moumen et al, 2015a).…”

Molecular Characterization of Fusarium Wilt Resistant and Susceptible Safflower (Carthamus tinctorius L.) Genotypes

“…Mahasi et al, (2009) and Khan et al, (2009) found out 61 and 78 amplified fragments from 14 and 15 RAPD primers and noticed 1-10 and 3-16 RAPD fragments generated per primer with an average of 5.5and 9.5 bands in safflower, respectively. On safflower same work was reported by Amini et al, (2008), and Souframanien and Gopalakrishna (2004) by using 15 and 25 RAPD primers which produced total polymorphic 132 and 44 bands and calculated amplified products range from 3 to 9 through standard of 1.8 and 13 bands for each primer, respectively.…”
