Heritability in wheat
-
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 study revealed highly significant differences for all the yield and its contributing traits, indicating the presence of high genetic variability. The phenotypic and genotypic co-efficient of variation (PCV and GCV) was high for grain yield per plant followed no of productive tiller per plant and moderate for plant height, spike length and thousand grain weight.

The changing climate adversely affect the morphological characters of plant which, ultimate effect the identification of off types in seed production programme. This also leads to effect the genetic purity in seed production programme. To overcome this problem selection of progeny and its breeding depend upon the genetic variability in population.

An experiment was conducted on genetic variability, heritability and genetic advance in wheat population including 48 F1’s + 48 F2’s + 16 parents in RBD during Rabi 2014-15. Analysis of variance for the design of experiments revealed that mean squares due to treatments were highly significant for all the ten characters studied, while mean squares due to replications were non-significant in both F1 and F2 generations.

Genetic variability, heritability, correlation and path analysis were estimated among 59 accessions of 08 quantitative characters in durum wheat. The highest value of GCV and PCV were observed for grain yield per plot, tillers per meter row length, spike length, grains per spike and test grain weight. It is also observed that the traits like grain yield per plot, tillers per meter row length, grains per spike and test grain weight exhibited high GCV also possesses high genetic gain indicating preponderance of additive gene effect for these traits.

What is an important food crop in India but of the entire world. The study indicates that the analysis of the variance showed highly significant differences for all the characters. Genetic variability indicated that high estimates of GCV and PCV were observed for the traits like 1000 grain weight, grains per spike, spikelets per spike, spike length and yield per plot. Further, high heritability coupled with high genetic advance as percent of mean was also observed, indicating the less influence of environmental variance in these characters.

A study was undertaken to estimate the heritability, genetic advance and coefficient of variation of yield and yield contributing traits in thirteen genotypes of wheat. The study was conducted in randomized block design (RBD) with three replications at Mountain Agriculture Research and Extension Station, Kargil (SKUAST-Kashmir) during kharif season of 2018. Significant genetic differences were observed for all the quantitative characters except flag leaf width, indicating considerable amount of variation among genotypes.

The genetic structure and differentiation of wild emmer wheat suggests that genetic diversity is eco-geographically structured. However, very little is known about the structure and extent of the heritable epigenetic variation and its influence on local adaptation in natural populations.

Wheat (Triticum aestivum L.), a staple food crop is of great commercial importance. Its production is restricted due to various abiotic stresses. There are indications that the wheat production is consistently limited by terminal heat stress. Here, performance of forty genotypes of wheat was undertaken for assessment of direct selection parameters (variability, heritability and genetic advance) and their relation with heat tolerance.

The Experiment was carried out to assess genetic variability with respect to grain yield and its components for heat tolerance in durum wheat. The values of phenotypic coefficient of variation in both sowing conditions were slightly higher than that of genotypic coefficient of variation for all the traits studied, indicating less effect of environment on the expression of characters studied.

The one hundred and seventy advanced homozygous lines were undertaken for estimates of mutual correlations vis-a-vis path analysis for grain yield with ten morphological traits Coefficient of variation being in the range of 1.40- 8.34 indicated adequacy of material and the traits studied for further estimation of genetic variability parameters. Mean squares due to genotypes were highly significant for all the characters observed, indicating the presence of adequate genetic variability for all the character studied.

Allogamyin the range of 0-5 percent is reported in wheat which is beneficial for hybrid development. To know the floral traits as well as their heritability that influence allogamy, twenty eight genotypes of bread wheat comprising of both male fertile and male sterile lines were grown under timely sown conditions.

Present investigation was carried out to study the variability parameters of quantitative as well as qualitative traits and their contribution towards seed yield which may be used as selection criteria for yield improvement in wheat under rainfed condition. Thirty six genotypes of wheat were studied for two consecutive years 2014-2015 and 2015-2016 following Randomized Block Design (RBD) with two replications in this experiment at Kalyani District of West Bengal.
