Green gram, Black gram, Pigeon pea and chickpea are common pulses in diet rich in carbohydrates, proteins and minerals. Numerous fungi affect pulses adversely causing reduction in seed content and seed health. During present study, effects of metabolites of seed-borne fungi on seed health are evaluated. Total seventeen fungi recorded from all test pulses. Out of these seventeen seed-borne fungi, six, Aspergillus flavus, A. fumigatus, A. niger, Drechslera tetramera and Rhizopus stolonifer, found to be common and dominant on four test pulses. These common and dominant seed-borne fungi produced mycotoxins that affected adversely to the seed germination, shoot and root length of test pulse Black gram in variable quantity.
The Cytogenetic studies were carried out in two important coldwater fishes, Rainbow trout (Oncorhynchus mykiss) and Snow trout (Schizothorax richardsonii), by Giemsa staining. The diploid chromosome number (2n) in Rainbow trout (Oncorhynchus mykiss) the modal diploid number was found to be 2n = 60. The karyotype formula obtained consist of 38 metacentric (M), 6 submetacentric (Sm) and 16 telocentric chromosomes (24M + 20 Sm + 16 T). The fundamental arm number was derived to be 208 (FN = 208) and in Snow trout (Schizothorax richardsonii), the modal diploid number was found to be 2n = 96. The karyotype formula obtained consist of 18 metacentric (M), 16 submetacentric (Sm) and 12 subtelocentric and 50 telocentric chromosomes (18 M + 28 Sm + 50 T). The fundamental arm number was derived to be 284 (FN = 284). This is the attempt to compare the wild snow trout obtained from Himalayan stream and farm raised Rainbow trout in these species using conventional staining.
