A protocol for in vitro multiplication of Capparis decidua (Forsk.) Edgew. has been developed from cultured leaves procured from multiplying axillary shoots on the cultured nodal explants. The highest efficiency of shoot formation was observed on Murashige and Skoog (MS) medium containing 2 mg dm -3 benzyladenine (BA) and 0.5 mg dm -3 1-naphthaleneacetic acid. The regenerated shoots were transferred to MS medium containing 3 mg dm -3 BA for growth and proliferation. Shoots above 2 cm in length were transferred to MS medium supplemented with 1 mg dm -3 indole-3-butyric acid plus 0.5 mg dm -3 indole-3-acetic acid for root induction. No variation was detected among the micropropagated plants by randomly amplified polymorphic DNA (RAPD) markers.
Eightyfive isolates of Colletotrichum lindemuthianum (bean anthracnose) collected from different kidney bean growing areas of a hilly state (Himachal Pradesh) of India, were characterized on the basis of their reaction types on International and CIAT differentials. On international differentials, 12 races viz., Alpha‐Brazil, Beta, Gamma and Ind I to Ind IX were characterized. The races designated as Ind I to Ind IX were different from those identified in Europe and USA, thus forming a new race group from the Indian subcontinent. On the CIAT differential set the 85 isolates have been grouped into 19 races. Of these, only races 65 and 73 resembled the North American races. Exotic accessions AB 136 and G 2333 were resistant to all the Indian races. However, race specific resistance has been found in a number of indigenous and exotic genotypes of Phaseolus vulgaris.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
