Role of heterosis for photosynthetic traits and sink organs in seed yield enhancement in safflower

چکیده
Abstract Genetic basis of heterosis has been exploited for yield improvement in safflower ( Carthamus tinctorius L.) but little is known about physiological yield. The objective this study was to quantify the seed by examining 19 hybrids and their parents photosynthetic traits, its components. results showed that components high positive low negative traits most studied. There were weak non-significant relations between Hybrids more efficient translocating photoassimilates two major sink organs viz. , number seeds capitula despite having net photosynthesis than parents. Seed increase sink-than source-limited necessary through organs. Heterosis breeding larger size with parallel effectiveness translocation photo-assimilates suggested safflower.

cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...

Selection of high yielding genotypes is very important in sunflower. Thus, 24 new sunflower hybrids along with Golsa cultivar were evaluated in a simple lattice design (5×5) with two replications in the Agriculture Research Station of Gorgan, north of Iran, during 2020. The genotype by yield × trait (GYT) biplot method was used in order to study the relationships between different traits and to...
