Evaluation of the sensitivity of new rice varieties to temperature according sowing dates and methods in the Senegal River Valley

Determining the extent and degree of germ plasm diversity and genetic relationships among breeding materials is an important aid in crop improvement research strategies with an understanding that genetic variability is the base for crop improvement providing an opportunity for plant breeders to develop new and improved cultivars with desirable traits and it is a key to reliable and sustainable production of crops through breeding. It has been also confirmed that measuring the available genetic diversity of crops is important for effective evaluation and utilization of germ plasms to explore their variability so as to identify necessary agronomic traits.
