Pastoralism beyond Ranching and Its Vulnerabilities as a Farming System, Especially in Semi-arid Tropics of Africa | Chapter 8 | Research Highlights in Agricultural Sciences Vol. 3

 Background Wheat is a chief crop that feeds millions of people, but its productivity is significantly reduced under high temperatures. Maintaining grain quality under climate change is critical for mortal nutrition, end- use functional parcels and commodity value.

objects The current study aimed at assessing the performance of 48 genotypes of wheat under two surroundingsi.e timely and late sown conditions, for assessment of mean performance, variability, correlation, and path analysis of quality and micronutrient traits.

Research Methodology The exploration was carried out in the experimental area of the Wheat and Barley Section, Department of Genetics and Plant parentage, CCSHAU, Hisar during 2019- 20. The assessment was done for 48 wheat genotypes under two temperature situations( timely and late sown terrain) in RBD design with three replications.

Results Heat stress caused a significant reduction in grain yield, grain appearance score, hectoliter weight, sedimentation value, iron and zinc content whereas an increase in crude protein, total gluten content, wet gluten content and total answerable sugar. In the present study, total answerable sugar, wet gluten content, total gluten content showed the loftiest values of variability, heritability and inheritable advance as of mean and therefore are the most important quantitative traits to be taken into consideration for effective selection. A positive correlation was seen between grain yield and hectoliter weight in timely sown terrain. Path analysis revealed the loftiest positive direct effect for hectoliter weight and sedimentation value in timely sown condition, while sedimentation value and iron content for late sown terrain and therefore in the process of selection important attention should be given to them as these characters are helpful for circular selection.

Conclusion A negative association between high yield and good quality should be an important target for the coming parentage sweats or to determine a quality parameter that performs constantly in both surroundings.
