In the changing climate scenario, drought could be continued as a major abiotic limitation for crop productivity. Finger millet although known for its drought tolerance, the drought stress decreases the grain yield from 25 to 100 percent depending on the duration and magnitude of drought stress. Present study was conducted to explore the genetic variability of selected genotypes over the ruling varieties if any, based on the extent of reduction in grain yield, and dependent photosynthetic traits due to moderate drought stress for 18 to 20 days (grand growth to flower primordial initiation).

An investigation was carried out with thirty six blackgram genotypes in rice fallow situation, to assess the variability, heritability and genetic advance for yield and yield attributing characters. The results revealed that high PCV and GCV for number of clusters per plant and high PCV coupled with moderate GCV for number of branches per plant and grain yield per plant exhibiting wider range of variability. Whereas, number of pods per plant and 100 seed weight recorded moderate variability.

The experiment was conducted at Agricultural and Horticultural Research Station, Kathal agere during kharif 2018. Estimation of variability parameters like environmental variability, Genotypic variability, Genotypic coefficient of variability, Phenotypic variability, Phenotypic Coefficient of Variability, Heritability (h2 ), Genetic advancement at 5%, Genetic advancement as % of mean 5% and General mean. In the present study twenty seven diverse hybrids were grown in RCBD design with three replications during Kharif 2018 to study the genetic parameters viz.

An experiment was undertaken by utilizing forty finger millet genotypes for eleven yield and yield contributing characters to assess genetic divergence. The analysis of variance has shown that there was significant variation among the genotypes in all the traits. The multivariate analysis carried out using Mahalanobis D2-statistics, indicated wider genetic diversity in the genotypes of finger millet.

The analysis of genetic diversity using D2 statistics clustered 33 selected genotypes of cultivated finger millet into ten different clusters. The cluster I had 8 genotypes and cluster II and IV had 9 genotypes each. The remaining clusters had only one genotype each. The inter cluster distance was highest (D=46.61) between cluster VII (GE4568) and cluster VIII (GE1200) and between cluster VII (GE4568) and cluster II (D=42.22). The trait days to 50 per cent flowering contributed more towards the genetic divergence of 33 selected finger millet genotypes.

A study was conducted at department of Poultry science, Madras Veterinary College, Chennai to record the qualitative characters of Aseel male chicken and to measure the biometric Characters of the birds. The skin, shank and eye colour were yellow and the colour was red in all the birds (100%). Sixty per cent of bird had red ear lobe and remaining 40% had pinkish red ear lobe. The comb type was ‘Pea’ in 80% of the birds, while it was ‘Rose’ in the remaining birds (20%). The beak colour was either brownish yellow (60%) or blackish yellow (40%). None of the birds had wattles (0%).
