Evaluation of sunflower hybrids under the climatic condition of Peshawar, Pakistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 2
Abstract
A field experiment was conducted at Botanical Garden, Department of Botany, and Islamia College Peshawar in order to evaluate the performance of different sunflower hybrids under the climatic conditions of Peshawar and to bring about the correlative study between different morphological and physiological characteristics. A randomized complete block design with three replications was applied using four sunflower hybrids Ass-501, S- 270, Samsung-30 and LG- 56.6. The statistical analysis of the data revealed that all sunflower hybrids were nonsignificantly different form one another with respect to days to flower initiation, days to 50% flowering, days to 100% flowering, days to head maturity, head diameter, plant height, 1000-seed weight, grain yield, oil content percentage. Performance of sunflower hybrids with respect to fatty acid profile was also non-significantly different from one another. In addition, positive and negative correlation was observed among different morphological and physiological parameters of these hybrids. It is concluded that all of the four sunflower hybrids perform, indicating that all of them suit equally to this climatic conditions. Simple correlation coefficient analysis proved that days to flower completion (100%), days to head maturity, plant height and 1000-seed weight had positive correlation with grain yield, while days to flower initiation, days to 50% flowering and head diameter had negative correlation with grain yield. The analysis of simple correlation coefficient also indicated that days to flower completion, days to head maturity and grain yield had positive correlation with percentage of palmitic, oleic and linoleic acid respectively. Therefore, these are worth characters to be taken by plant breeders for improving oil quality of sunflower hybrids. None of them supersede other, and all of them suit equally the climatic conditions of Peshawar.
