Marker-assisted selection in American cotton genotypes using biochemical and molecular profiling techniques

Biochemical and molecular markers have proven to be powerful tools for discerning bio-systematic, bio-geographic, and phylogenetic relationships. Bio-systematic information can be important for guiding traditional breeding programs, gene transfer, interspecific hybridization, and gene conservation. Polymorphism is a result of variation in the genome of an individual plant or animal organism. The present investigation of an experiment is conducted to explore the magnitude of polymorphism in cotton genotypes using biochemical and molecular marker techniques. In the present investigation, the cotton lines exhibited polymorphism is analyzed based on the relative mobility of bands. The relative mobility (Rm) values ranged higher in protein banding pattern followed by carboxylase esterases, peroxidases, and polyphenol oxidase activity studied by SDS-PAGE and PAGE electrophoresis techniques. In respect of the molecular investigation using RAPD, the primers used exhibited satisfactory amplification essential for discriminating the population. The most amplified primers exhibited an average polymorphism of about 73 percent. The biochemical and molecular marker techniques are found to be quicker for the screening of a large gene pool and clustering the genotypes into different diverse clusters which are useful to select the parents for hybridization. These techniques can assist plant botanists especially involved in plant breeding activities to speed up the conventional cotton improvement program. Further, it can be concluded that the biochemical and molecular markers investigated in the present experiment are adequate to judge the dissimilarity among the genotypes for speeding up the selection of parents with assumption that the banding profile is a measure of discrimination.

Students perception towards continuous and comprehensive evaluation in Erode district with reference to selected variables

The strength and success of an educational system depend on a sound examination system which is necessary to determine the effectiveness of the dissemination of knowledge by teachers and its assimilation by students. This is an attempt to know the perception of upper primary students towards Continuous and Comprehensive Evaluation in Erode district with respect to their selected variables such as sex, school type and medium of instruction. Student’s perception of CCE tool consists of Sixty six items was constructed by the investigator and the survey method was employed. Considering the hypotheses of the study, Correlation, descriptive and differential analysis ‘t’ and ANOVA were employed. The major findings of the study revealed that there is a significant means score difference in the perception of upper primary students towards CCE with respect to their Gender and Medium of Instruction. Keywords: Perception, upper primary students, Continuous and Comprehensive Evaluation

ICT Model (e-Kapas Network) for Dissemination of Cotton Agro-Advisory for Vidharbha region

Information and communication technology in agriculture (ICT in agriculture), also known as e-agriculture, focuses on the enhancement of agricultural and rural development through improved information and communication processes. Mobile Phone has emerged the scenario of communication. It is a fast and reliable source of communication for dissemination of Information related to new innovation or alter for upcoming calamities. Recent year the mobiles are becoming affordable and useful tool for farming community. Poor accesses to agricultural information are the major constraints in the growth of agricultural productivity in India. In this context e-Kapas Network Project under Technical Mission on cotton (TMC MM-1.6) ensures the availability of right information at right time at the doorstep of clients. ICAR-Central Institute for Cotton Research, Nagpur has introduced the novel extension mechanisms e-Kapas Network project nationally since April 2012. The AICCIP center of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was also one of participating center of this project with specific assignments to be completed in the various stages. These ICT Model were succeeded as the opportunities to the cotton growers to get relevant, location specific, timely agro-advisory services along with powerful platform for cotton scientists deliver appropriate cotton technologies to farmers to improve the efficiency of current manual system by saving time, money and making technologies available ‘anywhere & anytime’ to users. AICCIP, Akola under Dr. PDKV, Akola center has actively registered their participation by registering about 15,930 farmers from Vidharbha region along with document with fifty two FAQs and developed the script for documentary on rainfed cotton cultivation. The favorable attitude of farmers towards ICT as an effective and efficient information support tool would lead to stronger conviction and efficient extension programme planning in changing agri-rural environment.

A correlational and comparative study of perceived stress, intolerance of uncertainty and resilience among students and working individuals during the COVID-19 Pandemic

This study is aimed at investigating the correlation and comparison of perceived stress, intolerance of uncertainty and resilience among students as well as working individuals. The two main objectives of the research are to see if these three variables correlate with each other significantly; as well as to see the if there is a difference in the perception of intolerance of uncertainty, perceived stress and resilience between students and working individuals. The total sample consisted of 373 individuals falling between 18-40 years of age. Methodology consisted of snowball and purposive sampling. Descriptive, correlational and comparative research designs were used. Standardized tools of Perceived Stress Scale, Resilience Scale-14 and Intolerance of Uncertainty Scale were used for data collection in order to assess perceived stress, intolerance of uncertainty and resilience. The parametric measure of Pearson product moment correlation, independent sample t-test as well as regression were used for data analysis. The results revealed a significant positive correlation between intolerance of uncertainty and perceived stress and a significantly negative correlation between resilience and intolerance of uncertainty and resilience and perceived stress ( significant at 0.01 level). There is also a significant difference between perceived stress and resilience of the students and working individuals ( significant at 0.05 level).

Prevalence of Dysmenorrhea among adolescent girls of Govt. Senior Secondary Schools of District Mandi, H.P.

Adolescence is most important stage of human life, particularly in adolescent girls as it lays down the conditions for healthy and safe procreation. Many girls face problems in their menstrual cycle including dysmenorrhea, which has figured less in past research studies. To find out the prevalence of dysmenorrhea among adolescent school girls, to determine the association between the dysmenorrhea and quality of life as well as with other selected variables. A cross-sectional study was conducted on 378 adolescent Senior Secondary School girls of 13-18 years of age, selected through multistage sampling technique using structured pretested questionnaire. The data was computed and analyzed in SPSS 23 version. Results: The prevalence of dysmenorrhea was 65.3%. Most of the students were in the age group of 15-16 years. The mean age of respondents was 15.26±1.293 years while it was 13.41±.682 for menarche. The most common symptoms reported were backache in 66.7% and irritability in 40.7% of the cases. The study found positive association between dysmenorrhea and family history and fruit intake. Dysmenorrhea was also found related with school absenteeism, poor exam grades, poor interpersonal relationship, decreased concentration in class and day-to-day activity. The prevalence of dysmenorrhea among adolescent girls was relatively high. The pain suffered could be severe that affected school absenteeism, social and academic performance and day-to-day activities. Association of dysmenorrhea was found to be significantly associated with age of menarche while it was highly significant with family history and fruits.
