A comparison of the effect of gamma-rays ethyl methane sulfonate (EMS) and their combination for induced mutagenesis in two chilli varieties Kashi Anmol (KA-2) and VR-338 (Kashi Gaurav). 1000 chilli seeds each were irradiated with 10,15, 20, and 25 kR doses of gamma-rays treated, with 0.02, 0.03 0.04 and 0.05 M concentration of ethyl methane sulfonate and another 1000 seeds used for combination treatments were treated with all doses of gamma-rays followed by 0.03M EMS. The M1 generation was raised in protected nursery at Horticulture Research Farm, BHU, Varanasi during July 2011. Chlorophyll mutations were used to evaluate the mutagenic effeciency of various mutagens. The spectrum of chlorophyll mutants Albino, Chlorina, Viridis Xantha and Dark Xantha were most frequently observed in M2 generation. Gamma rays induced higher proportions of chlorophyll mutants than EMS and their combination. However, frequencies of viable chlorophyll mutants were observed in higher EMS and gamma-rays treatments than with their combination. Treatment with 15 kR gamma-rays was more effective in inducing chlorophyll mutations with highest frequency. Mutagenic effect generally increased with increasing dose of and gamma-rays EMS and their combination.Keywords

Immunisation protects children and adults against harmful infections before they come into contact with them in the community. Immunisation is given as an injection or, in the case of polio vaccine, taken as drops by mouth. The waste generated during the whole immunisation process must be disposed off properly. Improper waste disposal leads to serious health risks to recipients, health workers and the public. In King George's Medical University (KGMU) immunisation programmes are conducted regularly. Waste generated during the process are properly mutilated, collected, transported and disposed off. In KGMU a well established biomedical waste management system which disposed offs the waste as per the norms and legislation.Keywords

Nine parents and their eighteen hybrids from a line x tester design were evaluated for fruit yield and its components. Line x tester interaction was found significant for all the traits except, plant height considered variance due to treatment were found to be significant for all the characters under study. Whereas, variance due to lines was found to be a significant for all the characters except, days to 50% flowering and fruit length while variance due to testers was found nonsignificant for all the characters. On the basis of gca effects across three characters, RHRC-Cluster-Erect, PBC-535, LCA-235 and LCA-206 were identified as most promising parents for involving in hybridization programme aimed in improving number of fruit per plant as well as other important yield and yield contributing characters. Cross combinations, KA-2 x PantC-1, LCA-235 x Pusa Jwala, PBC-535 x PantC-1, RHRC-Cluster-Erect x Pusa Jwala, RHRC-Cluster-Erect x LCA-206 and RHRC-Cluster-Erect x PantC-1 were recorded specific combiner for fresh yield per plant due to positive significant of sca effect. The manifestation of heterobeltiosis for fruit yield per plant was evidenced by significant superiority of two out of eighteen crosses over better parent ranging from 6.87% in case of RHRC-Cluster-Erect x PantC- 1 to 13.48% in case of KA-2 x LCA-206 while rest of the crosses showed significant negative estimates of heterobeltiosis.The most promising crosses with significant positive heterobeltiosis for fresh yield per plant were KA-2 x LCA-206 (15.91%), PBC-535 x PantC-1 (20.10%), RHRC-Cluster-Erect x Pusa Jwala (16.32%), RHRC-Cluster-Erect x LCA-206 (42.60%) and LCA-438 x PantC-1 (16.26%).Keywords
