Variability and Association Studies in Tomato Germplasm under High-Temperature Arid Region

Genetic variability and correlation studies were carried out for 12 traits in 23 genotypes of tomato grown during spring-summer of 2009 under hot, arid agro-climatic conditions. Genetic variability, heritability and expected genetic advance revealed significant differences for all the traits studied. PCV and GCV were high for fruit weight, number of fruits per plant, plant height and fruit yield per plant. High heritability with high genetic advance as percentage of mean was observed for yield per plant (93.2%) as also for average fruit weight (92.8%), number of fruits per plant (73.4%) and plant height (50.1%) indicating the role of additive gene effects and for effectiveness of selecting for these traits. Correlation studies revealed that fruit yield had significant positive correlation with fruit weight, fruit length, fruit diameter and number of fruits per plant, both at the genotypic and phenotypic levels, indicating mutual association of these traits. Negative correlation of days to flowering and days to first harvest on yield per plant suggested indirect selection for earliness for yield improvement

Socio-economic factors Influencing Infant and Child Mortality among the Zou of Manipur

The present study was conducted to find out the influence ofsocio-economic factors on infant and child mortality among the Zou,a tribal population of Manipur. A cross-sectional study was executedamong 533 mothers of age 17- 49 years following house to housevisits from December 2016 to February 2017. The finding showsthere is a significant correlation of the educational level of themother, household income, child immunization to that of infant andchild mortality in the study population

Synthesis of Unusual Trimers in 1,3-Indandione

Dimethyl Sulphoxide-acetic anhydride reagent converts 1,3-indandione to the ylide (2) and a much awaited dimer (3) at room temperature. However , when 1,3-indandione was interacted with pre- heated  DMSO-acetic anhydride  at  waterbath temperature it affords an unusual trimer (4) and a novel compound (5), methine-tris-1,3-indandione  along with the ylide (2) Key words: DMSO, Acetic anhydride, Indandione,Ylide Trimer
