Abstract

I am pleased to write a foreword for this important Information Bulletin on Screening Techniques for Sorghum Diseases edited by RP Thakur, Belum VS Reddy and Kusum Mathur. This contains several chapters contributed by experts from ICRISAT, Patancheru, Indian Sorghum Programs and Texas A&M University, USA. Sorghum crops are attacked by more than 50 diseases incited by fungi, bacteria, viruses and nematodes often resulting in substantial economical losses to growers. However, there are only few diseases that are more important than others in different sorghum growing regions of the world. In this bulletin, the authors have addressed globally important diseases and compiled the information on screening techniques so critical for identification of resistance and its utilization in breeding for developing disease resistant cultivars. It is well established that the most effective and economical method of controlling sorghum diseases is by growing resistant cultivars. Accordingly, developing disease resistant sorghum hybrids and varieties has been the major research focus at ICRISAT and in other programs in the world. It is in this context that a simple and reliable screening technique is required to easily discern resistant and susceptible lines. It is good to note that the authors have provided the background information on importance of the disease, pathogen, symptoms and epidemiology before describing the screening technique and resistance sources that have been identified and utilized in breeding at ICRISAT, in Indian Programs and elsewhere. The authors have done a commendable job of compiling information pertaining to important diseases of sorghum in a simple and comprehensive manner. I am sure the bulletin will serve as a useful practical guide to sorghum researchers, teachers and students, and especially those who have interest in managing sorghum diseases through host plant resistance. I am pleased to note that small quantity seed of disease resistant lines reported in this bulletin can be made available to the requestor following the standard protocol of exchange of germplasm and breeding lines of ICRISAT.
