Inheritance of resistance to mycoplasma like organism in fenugreek (TrigoneJla foenum-graecum L.)

Abstract

Fenugreek (Trigonella foenum-graecum L.) is an important legume grown primarily as one of the seed spices. Besides, it is also used as a leafy vegetable. However, the basic genetic information is meagre owing to the lack of easily identifiable variants [1]. Empirical evidences suggest that the crop is affected by a number of pathogens. Like other legumes, it i3 also affected by mycoplasmal mycoplasma like organism (MLO). Although, it has been noticed continwilly at All India Coordinated Research Projects on Seed Spices, Jobner, no work has been done towards its identification and establish the genetics of resistance to such an organism. Although the available germplasm at this place show resistance to this organism, affected plants do appear sporadically in the populations of fenugreek, presumably as a result of mutation at anyone locus which governs disease reaction caused by the MLO. The present investigation aimed at tracing the inheritance pattern of resistance to the MLO in fenugreek.
