            Chilli parental varieties along with inter-and intra-specific cross varieties under 3 most popular chilli species (Capsicum annuum L.,Capsicum chinense Jacq.,Capsicum frutescens L.) at the research farm of Bidhan Chandra Krishi Viswavidyalaya, Directorate of Research, Kalyani, West Bengal. India were evaluated to study genetic variation and the relationship between yield and its component using a randomized complete block design during 2009-2011. There were significant variances among genotype of all traits. The phenotypic coefficient of variation (PCV) for all the characters of chilli varieties were greater than genotypic coefficient of variation (GCV), which emphasized the presence of environmental influence to some degree in the phenotypic expression of characters. Number of fruit(s)/plant had the highest PCV (119.97) and GCV (118.99). The findings imply that the narrow sense heritability (h2) was observed to be inferior to those of broad sense heritability (H2) for all the characters of chilli varieties. Genetic advance was observed for plant height (86.23), whereas genetic advance as percent of mean was highest for dry fruit weight (84.09). Greater heritability (h2) was linked with greater genetic advance (86.23) calculated for plant height, which suggested that the character is controlled by additive genes and therefore further advancement could conducted by selection. Fruit yield was significantly associated with most of the characters of chilli varieties at both genotypic and phenotypic levels; therefore, these are fundamental requirement to prepare a successful crop improvement program.

They are known to be highly toxic to cells, mainly through their action on cell reproduction. Many have proved to be carcinogens, mutagens or teratogens. Patients receiving therapeutic doses of these drugs have exhibited many adverse effects, including cancers. All people who came in contact with cytotoxic drug...

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
