Interest in reciprocal floral polymorphisms, such as heterostyly, has increased in recent decades because they can be used as suitable model systems to study mechanisms of outbreeding and disassortative mating in plants. Heterostylous plants are characterised by the presence of discrete morphs that differ in sex organ position and in some other ancillary traits. As regards sex organ deployment,...

this experiment was conducted to investigate the genetic diversity, relationship between morphological, agronomic and qualitative traits and to identify components of forage yield using some multivariate statistical methods in local sainfoin populations. the experiment was conducted as randomized complete block design with three replications in agricultural and natural resources research center...

this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...

Even though floral scent is of major importance for pollinator attraction, it less investigated than other traits. Previous studies suggest the joint exploration olfactory and visual cues to understand plant–pollinator interactions. We flower scents in Collinsia heterophylla, a bee-pollinated, annual herb with mixed-mating system combining self- outcross-pollination. In Collinsia, size developm...

genetic diversity is essential in the implementation of breeding programs. in order to determine genetic diversity, factor analysis and heritability of yield and some morphological traits, 20 strawberry cultivars were studied at the agricultural station of kurdistan research center using a randomized complete block design with three replications. morphological characteristics such as number of ...
