اساں مرنا ناہیں
اساں مرنا ناہیں
اج وی ساکوں یاد اے مرشد
پہرے دار دی گھات
یارہاں سال دی رات
پیریں اچ زنجیراں پا کے
نچدے گاندے لوگ
بلھے شاہ اساں مرنا ناہیں
وسدی راہسی جھوک
أحكام الخنثى بين العلم والأحوال الشخصية: دراسة فقهية مقارنة
This research addresses Islam's view of the social ties that man creates by virtue of his living among the people or in which he borns as its member, and aims to answer several questions about the relationship of these social ties with the Islamic brotherhood bond that Islam has brought. Does Islam recognize the social ties? On which basis does Islam recognize them and why? What is their position in front of Islamic brotherhood? How does Islam invest these ties to achieve religious, psychological and social security? Are there any conditions that Islam has developed to recognize and nurture these ties? The answer to these questions comes through the Qur’ānic texts, the prophetic Hadiths and the events of the Prophet's biography, based on open and direct reference, and away from the ambiguous interpretations or weak evidences; in order to clarify this matter clearly, and to check the validity of the results of the study.Genetic Basis of Water Stress Tolerance in Triticum Aestivum L.
Water stress is a key constraint in grain production of bread wheat. Using genomic and advanced breeding tools, genetic improvement in wheat and other crops is possible under water stress conditions. Fifty wheat genotypes were screened against water stress using traits like relative water contents and excised leaf water loss. Two water stress tolerant (Chakawal-50 and mairaj-08) and two susceptible (9436 and Millat-11) genotypes were identified and crossed to develop F1, F2 and backcross generations. Genetic analysis was conducted for relative water contents, excised leaf water loss, cell membrane thermo-stability, photosynthetic rate, stomatal conductance, CO2 assimilation, chlorophyll contents, plant height, flag leaf area, specific flag leaf area, peduncle length, spike length, number of tillers per plant, grain weight per spike, number of grains per spikes, 1000-grain weight, grain yield per plant and harvest index. Presence of additive, dominance and epistatic components were identified. Gene action was found complex showed that selection should be done in later generations for improvement of traits. Medium to high broad sense heritability, low to medium narrow sense heritability and low to high genetic advance was observed. Analysis under normal and water stress conditions revealed heterosis for relative water contents, excised leaf water loss, chlorophyll contents and plant height. Correlation analysis showed that relative water contents, cell membrane thermo-stability, photosynthetic rate and grain yield per plant were positively correlated with each other. Excised leaf water loss was negatively correlated with cell membrane thermo-stability, photosynthetic rate, relative water contents and grain yield per plant. A total of 30 ISSR markers were used to survey F2 population developed by a cross of Chakawal-50 (tolerance) and 9436 (susceptible) revealing a lots of DNA polymorphism. DNA polymorphism was used to construct genetic linkage map. In linkage analysis 73 bands produced from 4 ISSR markers were mapped on chromosomes. One QTL for photosynthetic rate on chromosome 3A, one for cell membrane thermo-stability on chromosome 2B and one for relative water contents on chromosome 4D was identified. These QTLs could be used to mold wheat genome into water stress tolerant wheat genome.Journals by Discipline
