Screening of the genotypes through plasmid assisted technology provides an efficient and handy tool for elaborating genetic relationships among the genotypes. Pea (Pisum sativum L.) genotypes (populations) obtained from different sources were analyzed through RAPD, DNA markers for evaluation of intraspecific DNA variations. The results revealed that significant variations were present in minor bands. Major bands also showed significant diversity. Variations were also recorded in the density of some common bands. Maximum and minimum Genetic Diversity i.e., 80% and 20% was found...

Almost 2 % of the entire plastic eventually get to the surronding, leading to sensitive polution harms. In addition polyethylene is petroleum based which is depleting with time. In this circumstance biobased plastic have gaind extensive significance as a possible alternative. Various bio degradable polymer have been developed. However, they have high cost and lower mechanical properties.To address this issue, different attemts are carried out such as blending of bio-polymeric renewable resourcess with polyolefins. Starch, chitin, chiyosan and cellulose are widely used as biodegradable...

Sunflower is the world fourth most important sources of edible oil. A lot of work has been done for varietals improvement through conventional breeding in Pakistan. In the present work, 16 cultivars (open pollinated population "OPP" and hybrid population "HP" eight each) of sunflower was evaluated. The study was aimed at evaluating the mineral composition, estimation of moisture contents, measuring electrical conductivity and 100 seeds weight. The mineral composition was fractionated though Atomic Absorption Spectrometer, which indicate that Zn+2 was 8.54 and 9.35%; Cu+2 0.5 and 0.02%; Mn+2...
