Screening of bioagents for seed biopriming in French bean (Phaseolus vulgaris L.) under Laboratory condition

Abstract

An investigation was carried out during (2016-17) at laboratory of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-273230 (H. P.). Nine indigenous isolates of bioagents including three plant growth promoting rhizobacteria (PGPR-1, PGPR-2 & PGPR-3), three rhizobial biofertilizers (Rhizobium strain- B1, Rhizobium strain- B2 & Rhizobium strain- P1) and three biocontrol agents (Trichoderma harzianum, T. viride & T. virens) were screened for their efficacy as seed biopriming under laboratory conditions following standard methods of seed quality and health testing as prescribed by ISTA. On the basis of these tests, PGPR-1 with maximum germination (), Rhizobium strain- B1 with highest germination () and T. viride with maximum germination () were performed best among their respective isolates.
