Millsp.]. The frequency of natural out-crossing of partially cleistogamous mutant lines, characterized by a modified keel and filamentous anthers, was studied at two locations in Sri Lanka and three locations in India. Indeterminate growth habit and normal floral morphology were used as dominant markers and the frequency of anural out-crossing was estimated as percentage of the observed hybrid plants. Natural out-crossing in the mutant lines in Sri Lanka ranged from 0.14 to 1.33% in comparison to 6.34 to 19.64% in the controls. In the Indian environments, natural outcrossing ranged from 0.16 to 2.67%. The mutant was higly stable over diverse environments, and may be of considerable economic importance in pigeonpea improvement and seed-production programs. date: 1994 date_type: published publication: Crop Science volume: 34 number: 3 publisher: Crop Science Society of America pagerange: 660-662 refereed: TRUE issn: 0011-183X official_url: http://dx.doi.org/10.2135/cropsci1994.0011183X003400030011x related_url_url: http://scholar.google.co.in/scholar?q=Frequency+of+natural+out-crossing+in+partially+cleistogamous+pigeonpea+lines+in+diverse+environments&hl=en&btnG=Search&as_sdt=1%2C5&as_sdtp=on related_url_type: author citation: Saxena, K B and Jayasekera, S J B A and Ariyaratne, H P and Ariyanayagam, R P and Fonseka, H H D (1994) Frequency of natural out-crossing in partially cleistogamous pigeonpea lines in diverse environments.
