This study determined the potential for genetic introgression of salinity tolerance from a wild relative, Atylosia albicans (W. & A.) Benth., to cultivated pigeonpea, Cajanus cajan (L.) Millse. A sand culture system was used to grow the salt-tolerant A. albicans, salt-sensitive C. cajan, and their F1 hybrids at various precisely maintained salinity levels. The results demonstrated the feasibility of transferring salinity tolerance from A. albicans to C. cajan. The high level of salinity tolerance in A. albicans was expressed as a dominant genetic factor in both the reciprocal F1 hybrids of this species and C. cajan. The physiological attributes conferring salinity tolerance in A. albicans and the F1 hybrids include Na and Cl retention in the roots and limited translocation to the shoots, high K selectivity, and maintenance of transpiration rate under saline conditions date: 1990 date_type: published publication: Crop Science volume: 30 number: 4 publisher: Crop Science Society of America pagerange: 785-788 refereed: TRUE issn: 0011-183X official_url: http://dx.doi.org/10.2135/cropsci1990.0011183X003000040005x related_url_url: http://scholar.google.co.in/scholar?as_q=Salinity+Tolerance+in+F1+Hybrids+of+Pigeonpea+and+a+Tolerant+Wild+Relative&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&btnG=&hl=en&as_sdt=0%2C5 related_url_type: pub citation: Rao, G V S and Johansen, C and Rao, J V D K K and Jana, M K (1990) Salinity Tolerance in F1 Hybrids of Pigeonpea and a Tolerant Wild Relative.
