Phenotypic and molecular marker distance as a tool for prediction of heterosis and F1 performance in sunflower (Helianthus annuus L.) under well-watered and water-stressed conditions
The aim of this study was to determine phenotypic and genotypic distances in parental lines of diallel population of sunflower, and to identify correlation between both distances with F1 performance, specific combining ability (SCA) and absolutely mid-parent heterosis. The morphological distance (Euclidean distance; EDs) and genetic distance (Jaccard`s distance; JD) among five sunflower parenta...
متن کاملGenetic analysis and QTL mapping of agro-morphological traits in sunflower (Helianthus annuus L.) under two contrasting water treatment conditions
The present study was undertaken to investigate the genetic basis and map quantitative trait loci (QTLs), controlling agronomic traits in sunflower under well-watered and water-stressed conditions. Recombinant inbred lines (RILs) coming from the cross between sunflower parental lines PAC2 and RHA266 were evaluated in a rectangular 89 lattice design with two replications in each treatment condi...
متن کاملProfitability Assessment of Abscisic Acid Application on Sunflower (Helianthus annuus L.) Hybrid under Drought and Well Watered Conditions
Profitability assessment has prime importance for every crop husbandry practice and cultural operation. For this purpose, two field experiment was carried out to investigate the response of spring planted sunflower hybrids to different irrigation levels/schedules and foliar application of abscisic acid. Two studies were done at the Agronomic Research Farm, University of Agriculture, Faisalabad,...
متن کاملCombining ability analysis for seed yield and its components in Sunflower (Helianthus annuus L.)
Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...
متن کاملEffect of deficit irrigation on seed yield and yield components of sunflower (Helianthus annuus L.) hybrids
This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
