Genetic variability studies for yield

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.

Salinity is an abiotic stress that negatively affects soybean [Glycine max (L.) Merr.] seed yield. Although a major gene for salt tolerance was identified and consistently mapped to chromosome (Chr.) 3 by linkage mapping studies, it does not fully explain genetic variability for tolerance in soybean germplasm.

Quantum of genetic variability and the extent to which heritable and nonheritable variations are related to the characters, determines the extent of genetic amelioration. The present investigation was carried out in kharif, 2019 to understand the clustering pattern and correlation for yield attributing traits in aromatic landraces of rice. Here 90 aromatic rice landraces along with six check varieties were evaluated for 10 quantitative characters. Cluster analysis divided these 96 rice genotypes into 4 clusters.

In the present study, it is clear that it is possible to develop high yielding lines with high quality traits with superior nutritional features. The parameters have indicated sufficient variability for different nutritional characters, so that it would enable the breeder to utilize appropriate genetic resources in the crossing programme to improve the particular character.

The objectives of this study were to identify promising rice genotypes and evaluate the genetic variance and effectiveness of selection of the rice varieties for several yield attributing traits. A varietal trial of fifteen rice genotypes was laid out in a randomized complete block design (RCBD) with three replications in a farmer’s field in Sundarbazar, Lamjung, Nepal during the rainy season of 2018.

Present investigation of genetic variability, correlation and path analysis for yield and yield contributing characters in 22 genotypes of foxtail millet was carried out during kharif, 2019 at JNKVV, College of agriculture (Rewa, M.P.). Mean value of ear length and grain yield per plant was also observed highest for genotypes SiA-3159.

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.

The present study was carried out to evaluate fifty wheat genotypes of different ecogeographic origin. Data on eight quantitative characters viz., Plant height, reproductive tillers/plant, length of spike, spikelets/spike, days to maturity, grains/spike, test weight and grain yield/plant were recorded.

The sensitivity of rice to high temperature varies with growth phase, an increase in day/night temperature and genotype (Yoshida et al., 1981). Planning and execution of any breeding program for improvement on quantitative traits depends on magnitude of genetic variability.

Twenty local maize germplasm collected from various parts of Nagaland along with a check variety was laid in randomized block design with two replications in the research farm of School of agricultural research and rural development, Nagaland University, Medziphema during kharif 2019 to determine the variability present amongst the genotypes. The results showed significant differences for all characters studied except for number of ears per plant.

The material for the present study consisted of 30 F4 families of bhendi, to assess the genetic components for growth and yield at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, UT of Puducherry, India. The mean values and ranges recorded for various traits under study revealed significant variation. The maximum range of variability was observed for fruit yield plant-1 (148.0 to 377.31 g), followed by plant height at final harvest (76.56 to 160.40 cm).

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.

Thirty six diverse genotypes of Indian mustard (Brassica juncea L. Czern and Coss.) were evaluated for ten quantitative. The variability indicates that Genotypic coefficient of variation (GCV) was moderate for 50% flowering, days to maturity, total no. of siliqua per plant, biological weight, test weight and seed yield; low for plant height, no. of siliqua on main shoot, no. of seed per siliqua and harvest index.

A field experiment was conducted to estimate the genetic variability, trait association and path coefficient analysis among the Indian mustard genotypes during rabi, 2019. Analysis of variance revealed the mean sum of squares due to genotypes was highly significant for all the characters studies indicating the existence of ample variability among the genotypes studied. The high GCV and PCV observed for number of siliquae per plant and secondary branches per plant indicated the influence of environment on the expression of these characters were at minimum level.
