Abstract:
Fifty four confectionery inbred lines of sunflower along with three checks were evaluated during Spring 2019 and 2020 for 17 agro-morphological traits. Seed yield/ plant exhibited positive correlation with 100-seed weight during 2019 whereas, with days to flower initiation, plant height, stem girth, head diameter, head weight, biological yield and filled seeds/ head during 2020. Significant negative correlation was seen among seed yield per plant and seed length during 2019. According to pooled data, significant positive correlation was observed by seed yield per plant with days to flower initiation, days to maturity, plant height, head diameter, stem girth, head weight, biological yield and filled seeds per head whereas, negative significant correlation with seed width. The path coefficient analysis revealed maximum positive direct effect on seed yield/ plant exhibited by 100-seed weight followed by stem girth in 2019 whereas, during spring 2020 filled seeds/ head, seed volume weight were major contributors towards seed yield per plant. Based on path analysis of pooled data biological yield, filled seeds per head, harvest index and head weight can be used for indirect selection for seed yield per plant.
