Tomato is one of the important vegetable crops being cultivated throughout India. Rapid deterioration of stored vegetable seeds is a serious problem which occurs at an increasing rate in uncontrolled storage environment. The present study was aimed at investigating the effects of zinc oxide nanoparticles (nano-ZnO) on tomato seeds during aging. The experimental treatments included four concentrations of nano sized ZnO (400, 600, 800, and 1000 mg/kg), and control (without any ZnO ) on fresh and aged seeds. Results indicated that the highest and the lowest vigour index (1986 vs. 1521) were obtained in 600mg concentration of nano sized ZnO and control treatments,, respectively in fresh seeds. During aging, vigour index was maintained significantly as 995 with 600mg nano sized ZnO treated seeds when compared with control (495). This study shows that employing ZnO nanoparticles could reduce tomato seed deterioration during aging and promote the seed germination.Keywords

An experiment was conducted to study the variability and association between characters in rice. 36 genotypes of rice were evaluated and obtain information on variability parameters and correlation analysis for 18 characters. Analysis of variance revealed high significant differences for all the 18 characters studied. Phenotypic co-efficient of variation (PCV) was higher than genotype co-efficient of variation (GCV) for all the characters indicating the little influence of environment on the characters. Number of unfilled grains per panicle had maximum GCV followed by grain yield per plant, harvest index, biological yield per plant, number of filled grains per panicle and grain L/B ratio. All the qualitative characters depicted high estimates of heritability, which indicates preponderance of additive gene action in the inheritance of these characters. High to moderate degree of genetic advance was observed for number of filled grains per panicle followed by biological yield per plant. Grain yield per plant showed positive and significant correlation with number of filled grains per panicle followed by harvest index, biological yield per plant and panicle length at phenotypic and genotypic level. Thus, these characters may serve as effective selection parameters during breeding programme for crop improvement.Keywords
