Sequential path analysis for determination of relationships between yield-related characters with yield in rice (Oryza sativa L.)

  Rice (Oryza Sativa L.) is one of the most important food crops in the world. Path coefficient analysis has been widely used in crop breeding to determine the nature of relationships between the grain yield (GY) and its contributing components. A field experiment was conducted in 2009 at Rice Research Station in Tonekabon, north of Iran. This experiment was arranged in a randomized complete block design...

Biochemical and molecular investigations on prime mechanisms of induced resistance in French bean (Phaseolus vulgaris L.) and soybean (Glycine max L.)

  The prime mechanisms of induced resistance in French bean and soybean plants were investigated against three pathogenic fungi, namely Fusarium solani f. sp. phaseoli, Fusarium solani f. sp. glycine andColletotricum lindemothianum. This latter fungal pathogen was chosen for a comparative purpose, as it represents a non related genus of the main fungal pathogens used in this study....
