Pigeonpea References Breeding/Genetics Gene Symbols in Pigeonpea K B Saxena 1 , Rajini Raina 2 ,and R V Kumar 1 (1. Genetic Resources and Enhancement Program (GREP), International Crops Research Institute for the Semi- Arid Tropics (ICRISAT), Patancheru 502 324, Andhra Pradesh, India; 2. Banaras Hindu University, Varanasi 221 005, Uttar Pradesh, India) Pigeonpea (Cajanus cajan (L) Millsp.), also called as 'red gram' in India, 'Nandolo' in Malawi, 'Gandul' in Puerto Rico, 'Mu Dou' in China and 'Quinchocho' in Venezuela, is an important pulse crop of the semi-arid tropical regions of the Indian subcontinent, Africa, and the Caribbean. A large genetic variation exists within this species for different quantitative and qualitative traits (Remanandan 1990, Saxena and Sharma 1990). A number of genetic studies have been conducted in the past and gene symbols assigned. In this paper an attempt has been made to compile information on gene symbols for a number of traits. The studies conducted by different authors have been grouped together appropriately and we have not made any attempt to equate them or to reinterpret the published data. A compilation of originally assigned gene symbols in pigeonpea and in some interspecific crosses, involving pigeonpea and its wild relatives, is respectively summarized in Table 1 and 2. This compilation is the first such attempt in pigeonpea and the information will be useful in assigning gene symbols in future. Also, it will avoid duplication of the gene symbols. In most cases the information has been obtained directly from the published articles and attempts have been made to reproduce them in the original form. However, the authors could not acquire two research papers (marked with *) and the information has been cited using other related publications. The authors would appreciate comments from readers regarding any errors of content and/or omission. In this review an attempt has also been made to provide information about genetic variation considered for study, the details about the genetic control of various phenotype(s) is not discussed for the sake of brevity and for such details the readers are advised to refer the original articles. 30 ICPN 7, 2000 Chaudhari, A.N., and Thombre, M.V. 1975.
