Correlation and path coefficient analysis for the yield components of Safflower germplasm (Carthamus tinctorius L.)

Studies on genetic variability, character association and path analysis in Niger {Guizotia abyssinica Lf. (Cass)} genotypes

“…High heritability (h2) with moderate genetic advance (GA) as percent of mean showed for the characters days to 50% flowering plant height and diameter of the capitulum suggested that both additive and non-additive gene effects were involved in the genetic regulation of these traits. These results supported prior findings by Pushpa et al(2023) [17] , Baghel et al (2018) [2] in Niger and Valli et al(2016) [28] in safflower regarding days to 50% flowering. High heritability (h2) with low genetic advance (GA) as percent of mean was displayed by days to maturity, and it was in similar agreement with Bamrotiya et al (2016) [4] in Niger and Valli et al (2016) [28] in safflower.…”

“…All of these features could be subject to selection in an effort to boost genotype magnitude. A comparable outcome was noted by Valli et al (2016) [28] for test weight in safflower. The findings aligned with the anticipated outcomes as reported by Baghel et al (2018) [2] in relation to the oil content and Baghel et al (2018) [2] and Bamrotiya et al (2016) [4] in Niger for number of branches per plant, number of capitula per plant, number of seeds/capitulum and seed yield/plant.…”

Character Association and Path Analysis Studies at Genotypic Level on Some Genotypes of Safflower (Carthamus tinctorius L.)

“…It had significant positive correlation with biological yield per plot (kg) (0.783), seed yield per plot (kg) (0.677) and volume weight (gms./100 ml water volume) (0.399). Our results are supported with the findings of Hoshang et al,(2013), Hussain et al, (2014, Tamoor et al, (2014), Nag (2015), Kumar (2016), Achhale (2016), Semahegn and Tesfaye (2016), Manjhi (2017), Valli (2016 and Puspavalli et al,(2017) 100 seed weight (gms.) had positive nonsignificant correlation with harvest index % (0.362).…”

Genetic variability and character association studies among seed yield and yield component traits in safflower (Carthamus tinctorius L.) genotypes

“…The capitulum diameter was positively and significantly indirectly correlated with number of seeds/capitulumand seed yield/plant.Number of capitulum/plant and number of seeds/capitulum had positive and significant indirect correlation with petal yield/plant. These results are in contrary to Rathod et al (2021), Mali et al (2022) and Valli et al (2016).…”
