The present study was conducted at Department of Seed Science and Technology, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bangalore during 2011-12 to reveal the influence of maturity stages and post-harvest ripening on seed quality among ten (Bhut jolokia, Merkera local, Sweet baccatum, Gandhari, Biligiri local, Majjige menasu, Chinense habanero, Hot cherry, Cherry pepper and Shivani) chilli genotypes belonging to Capsicum chinense, C. frutescence and C. annuum. The results revealed that among maturity stages, fruits harvested at red ripe stage and subjected for 20 days post-harvest ripening (M4) has recorded higher seed quality parameters viz., 1000 seed dry weight (6.95 g), seed germination (66.0 %), seedling length (9.9 cm), seedling dry weight (1.50 mg), seedling vigour index-I (748), total dehydrogenase activity (1.314), α-amylase activity (34.9 μg maltose ml-1min-1) and field emergence (56.0 %). Also minimum electrical conductivity (1.743 dSm-1) and moisture content of fresh seed (10.93 %) was noticed.Keywords

Evaluation of eleven germplasm lines of the Indian spinach (basella) revealed maximum leaf weight/plant in IIHR-1 (160.5g), followed by IIHR-18 (111.6g) and IIHR-3 (98.3g). Results of genetic studies revealed that phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the traits studied, indicating environmental influence on expression of these characters. Moderate heritability along with high genetic advance was recorded for leaf weight and total plant weight, indicating the presence of additive gene effects. Hence, selection can be employed for improvement of these characters in basella. Higher plant weight was found to be significantly and positively associated with branch number, leaf number, leaf weight and stem weight. Leaf number had the maximum direct positive effect on total plant weight, followed by leaf length. Indirect effects of other characters through these characters were also seen to be positive. Thus, for yield improvement in basella, emphasis may be laid on indirect selection through leaf characters like leaf number, leaf length and leaf weight.Keywords
