شریعت اسلامی میں رسم و رواج کے ساتھ تعامل کا جائزہ: مختلف اسلامی ادوار کی روشنی میں

Customs and traditions have a significant role in the social set up of every society. These customs project a picture of its culture, manners, beliefs, mental inclinations and life style. For social advancement, it is necessary for a nation to take reformative steps with respect to changing situations. They should adopt the customs that are productive and avoid the harmful ones. It has been a ground reality that the progressive nations have got the leading position having modifying their customs and traditions, while those who have been conservative are backward in the global race restricting on their outdated norms and so called customs.  In the prestigious age of the Holy Prophet (BPUH) and his followers, various laws and principles were formulated for the uplift of society, which provided a broad based concept of “custom”. The Islamic jurists have taken the custom as a source of Islamic legislation. In the article under reference, custom has been highlighted with respect to Islamic thoughts in various ages of Islamic history in a number of recommendations have been presented in order to uplift the society and to aware the Muslim theologians and Muftees accordingly.

Genetics of Quality and Yield Related Traits in Spring Wheat Triticum Aestivum L. under Terminal Heat Stress Conditions

Wheat crop is a basic staple food in many of countries all over the world. To overcome the need and supply gap of food it is necessary to improve wheat yield against different stresses such as heat stress. This study was performed to enhance the knowledge about genetics of heat tolerance in wheat using different agro-morphological parameters for screening of wheat. Line × tester mating design was used to access the genetic variability of wheat for combining ability against normal and heat stressed conditions. One hundred twenty genotypes were sown in research area of Wheat Research Institute (WRI) of Auyb Agriculture Research Institute (AARI) Faisalabad during growing season of 2014-15 in field and tunnel, which was covered during grain filling stage to provide high temperature stress. Ten lines and five testers were selected after proper screening by using different screening parameters such as cell membrane thermostability, normalized difference at vegetative stage, canopy temperature at vegetative stage and relative water content. The selected lines and testers were crossed in Line × Tester mating fashion. In next growing season (2015-16), parents along with their F1 hybrids were sown in triplicated randomized complete block design (RCBD) under normal and tunnel conditions. Data were recorded for both normal and heat stressed conditions for following traits i.e. cell membrane thermostability, normalized difference at vegetative stage, normalized difference at grain filling stage, canopy temperature at vegetative stage, canopy temperature at grain filling stage, relative water content, plant height, flag leaf area, peduncle length, spike length, number of fertile tillers per plant, days to heading, days to maturity, spikelets per spike, grains per spike, thousand grain weight, grain yield per plant and other quality traits like protein , moisture contents, starch, ash, gluten and test weight. Combining ability as used to investigate genotypes with best GCA and SCA. These parameters can help breeders in wheat crop improvement. All traits in this study showed dominance type of gene action under both normal and heat stressed environments. Results showed that the parents V-12103, Miraj-08, Faislabad-08, V-12082, Millat-11 and Chenab-2000 were good general combiner for grain yield and quality traits under both normal and heat stressed conditions. Among different crosses, V-13013 × ND643, SW89.52277 × Chenab-2000 and V-13013 × V-12082 showed better performance for grain yield and quality related traits that can be used in further breeding program for improvement of grain yield and quality parameters of wheat.
