Genetic Variability Studies for Economically Important Traits in Sunflower (Helianthus Annuus L.)
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 2, Issue 2
Abstract
The research was conducted in the research area of Department of Plant Breeding and Genetics (PB&G), University of Agriculture Faisalabad (UAF), Pakistan during spring 2014. The triplicated research trial was laid out following randomized complete block design (RCBD). Fifteen lines of sunflower were studied for genetic variability and association of economic traits with seed yield. The data were recorded on quantitative traits i.e. days to 50% flowering (DFF), plant height (PH), number of leaves per plant (NOL), head diameter (HD), leaf area (LA), filled achene (FA), 100 achene weight (100AW), oil contents (OC), achene yield per plant (AY/P) and qualitative traits i.e. head angle at maturity (HA), achene color(AC). The recorded data were subjected to analysis of variance, correlation and path coefficient analysis. The accessions were highly significant for all traits under study. The accessions A-2.2 showed good performance for most of studied traits. The accession B-3.1 also show better performance followed by A-4.3 and A-7.10. Genotypic correlations are higher than phenotypic correlations. 100AW, NOL, LA and HD had positive and highly significant genotypic correlations with AY/P. Genotypic correlation of AY/P was significantly negative with PH, DFF and oil contents. LA, NOL, 100AWand OC showed direct positive effect on AY/P. DFF, PH, HD and FA had negative direct effect on AY/P.Oil and fats are major part of human diet, important source of energy and also play role in carrying different vitamins in body. Due to the rapid growth in population of Pakistan, requirement of edible oil has also been raised. So a gap is produced between utilization and production in Pakistan. Although the country is making huge improvement in agriculture sector but still there exist extreme shortage of edible oil. During 2015-2016 Pakistan fulfilled 17% its requirement of edible oil by domestic oil and 83% by imported oil. Both conventional and non-conventional oilseed crops are important to fill the space between utilization and production.
