Climate change has a negative effect on the environment in which traditional fruit species are grown and, at same time, offers potential for cultivation of new species. Japanese plums derived from P. salicina Lindley that is slowly being introduced to Czech Republic. Therefore, there efforts find ways grow these varieties. In our experiment, selected nursery traits important production plum sap...

Fertility reduction due to sub-fertile males is a major concern in breeder flocks. Phenotypic traits of broiler breeder males and their relationships with fertility can be used as reliable indicators for identification and removal of sub-fertile males from the breeder flocks. This study was conducted to investigate semen traits (semen volume, sperm motility, sperm viability and sperm count) and...

Different pollinators can exert different selective pressures on floral traits, depending on how they fit with flowers, which should be reflected in the patterns of variation and covariation of traits. Surprisingly, empirical evidence in support of this view is scarce. Here, we have studied whether the variation observed in floral phenotypic integration and covariation of traits in Narcissus sp...

The study compares gross revenues from modern rice varieties and landraces and valuates different useful traits of rice landraces to demonstrate an empirical methodology for biodiversity valuation. A sample of 200 rice growers in hills and plain area was surveyed for commercialization of agro-biodiversity project. For estimating the value put by the consumers on different rice traits a hedonic ...
