Registration of ICPL 87154, a Partially Cleistogamous Pigeonpea Breeding Line with Low Natural Out-crossing
ICPL 87154 (Reg. no. GS-8, PI 597941), a pigeonpea [Cajanus cajan (L.) Millsp.] breeding line, was developed at ICRISAT Asia Center, Patancheru, AP, India. This line was released by the ICRISAT Plant Materials Identification Committee in 1993. The primary gene pool of pigeonpea has typical leguminous flowers, which on average permit about 20% insect-aided natural out-crossing (1). At ICRISAT, a...
متن کاملProtease Inhibitors in Wild Relatives of Pigeonpea against the Cotton Bollworm/Legume Pod Borer, Helicoverpa armigera
Cotton bollworm/legume pod borer, Helicoverpa armigera is one of the most damaging pests worldwide. Because of the difficulties associated with chemical control of this pest, emphasis has been placed on developing transgenic plants with resistance to H. armigera. Since toxin genes from the bacterium, Bacillus thuringiensis (Bt) have been deployed on a large scale, there is need to scout for alt...
متن کاملGenetic Patterns of Domestication in Pigeonpea (Cajanus cajan (L.) Millsp.) and Wild Cajanus Relatives
Pigeonpea (Cajanus cajan) is an annual or short-lived perennial food legume of acute regional importance, providing significant protein to the human diet in less developed regions of Asia and Africa. Due to its narrow genetic base, pigeonpea improvement is increasingly reliant on introgression of valuable traits from wild forms, a practice that would benefit from knowledge of its domestication ...
متن کاملResistance to Meloidogyne javanica and Rotylenchulus reniformis in Wild Relatives of Pigeonpea.
Meloidogyne javanica and Rotylenchulus reniformis are important nematode pests of pigeonpea. Greenhouse evaluation of 66 accessions of 25 species of Cajanus, Rhynchosia, and Flemingia for resistance to M. javanica based on number and size of galls, galled area of root, and number of egg masses showed resistance to be available in these wild relatives of pigeonpea. Thirty-five accessions had </=...
متن کاملFertility restoration in cytoplasmic-nuclear male-sterile lines derived from 3 wild relatives of pigeonpea.
Three cytoplasmic-nuclear male-sterile (CMS) lines, one each derived from Cajanus sericeus (A(1) cytoplasm), Cajanus scarabaeoides (A(2) cytoplasm), and Cajanus cajanifolius (A(4) cytoplasm), were crossed to 7 pigeonpea (Cajanus cajan (L.) Millsp.) cultivars in a line x tester mating scheme to study the fertility restoration of the CMS lines. Twenty-one F(1) hybrid combinations were planted in ...
