In breeding for plant disease resistance programs, a large number of new improved genotypes are tested over a range of test pathogens or environments and the underlying statistics used to model this system may be rather complicated. Due to ordinal nature of most measured traits of disease responses, some nonparametric methods used for analyzing genotype × environment (GE) interaction in two dat...

This study shows the effect of soil structure, soil texture and different types of nutrients on the growth of Ammi visnaga (L.) Lam, as well as the yield of the fruit crop and its content of the main active principals (ɣpyrones). The study was carried out in several localities in Two Arabian countries in North Africa; Egypt and Sudan. Egypt: at three localities:-1st at Mepaco Farm in Enshas El-...

Stability analysis of grain yield is an efficient tool for the selection varieties adapted to fairly wide cultivation zone. A study aims determine adaptability and stability agronomic performance 10 elite Doubled Haploid (DH) rice genotypes generated through another culture technique, along with local cultivar Umgar as a check under irrigated lowland conditions in three different environments c...

Rice (Oryza sativa L.) is an important global food commodity crop. Its yield was affected by genotype, environment, and the interaction between genotype environment that demands development of diverse tolerant rice to increase yields adaptation. Genotype Environment for Tongil types with doubled haploid (DH) were evaluated in three locations. A randomized complete block design replicated times ...
