Drought is a major threat to wheat production worldwide and development of drought-tolerant wheat genotypes may improve the production of this cereal crop in drought affected regions. In the present study, 24 mutant lines were developed by treating a wheat variety ‘NN-Gandum-1(NN-1) with ethyl methane sulfonate (EMS). The M5 , M6 , and M7 generations were evaluated for quantitative traits under well irrigated and rainfed conditions. Furthermore, best performing mutants of M6 and M7 generations were examined for biochemical parameters.

An experiment was conducted with 9 colocasia [Colocasia esculenta var. antiquorom Schott.] genotypes to evaluate the estimate of genetic variability for different characters. The experiment was conducted using a Randomized Complete Block Design with three replications. The genetic parameters between yield and yield contributing characters of different colocasia genotypes were studied. Analysis of variance showed significant variation among the genotypes for all tested characters.

An experiment was conducted to study the nature and magnitude of genetic variability with a view to identify promising genotypes for yield and related traits in linseed. Eighteen diverse linseed (Linum usitatissimum L.) genotypes were evaluated in randomized block design in three replications during rabi 2019-20 for twelve agro morphological characters to assess the genetic parameters of variability.

The major thrust in dairy cattle breeding programme has been to identify potential parents with high breeding value for next generation. In general, two breeding strategies are available for improvement of cattle, i.e. selective breeding with in a breed and cross breeding among breeds (Falconer and Mackay, 1996). For the formulation of effective genetic improvement programme, basic knowledge of genetic parameters of a herd must be known with maximum accuracy.

The present investigation was carried out to estimate different genetic parameters in ricebean germplasm of NW Himalayas. Forty germplasm lines of rice bean were evaluated for yield and its components in Kharif, 2015 at the experimental farm of CSKHPKV, Palampur. High PCV and GCV was observed for seed yield/plant, plant height, pod length, pods/cluster and clusters/plant indicating the role of these characters for effective selection.

Increasing seed yield and oil content is one of the most important goals in sunflower (Helianthus annuus L.) breeding programs. The aim of any plant breeder includes selection from natural population or artificially developed for one or several characters. In the present investigation, twenty sunflower hybrids were evaluated for various parameters under field conditions to estimate genetic parameters, correlation coefficient and path analysis.

The current work was focused on evaluating 24 sorghum accessions for fodder yield potential and nutritional quality during summer 2015 in the Department of Forage Crops, TNAU, Coimbatore. Plant samples were collected at 50% flowering stage and evaluated for nine fodder yield and 13 forage quality parameters. Grounded samples were used for assessing the fodder quality.

Thirty basmati rice genotypes were evaluated in RBD with three replications with an objective of assessing the genetic variability, heritability, genetic advance for twenty-two yield and quality characters. The results of ANOVA revealed that the mean sum of squares among the genotypes for all the characters were highly significant indicating the presence of ample amount of variability which can be exploited for selection of characters for crop improvement programme.

The investigation was carried out to estimate the component of genetic variability and associated parameters among 12 IRRI CMS lines and evaluated for morphological characteristics that influence outcrossing rate in hybrid rice. There was a marked variation in out crossing rate of CMS lines ranging from 18% to 45% under uniform weather conditions for all the CMS lines. Variation in plant height, number of panicle per plant and panicle length appeared to have an influence on outcrossing rate.

Thirty Desmodium gangeticum (L.) DC. accessions were evaluated for genetic variability, heritability and genetic advance for four yield attributing traits collected from different parts of India. The analysis of variance for mean squares for different characters was found to be highly significant for most of the characters under study except for lamina width, petiole length and internode length.

Twenty five genotypes of carrot were evaluated for different traits in a randomized complete block design with two replications. The variation was observed for all the parameters studied. Root weight, root/top length ratio, total yield/plot, total yield/ha, cortex thickness, TSS, β-carotene content, ascorbic acid content, total phenol, protein, root forking and root splitting showed high genotypic coefficient of variation and phenotypic coefficient of variation.
