  In mustard (Brassica juncea) broad-sense heritabilities, coefficients of variability and genetics advance values were computed for primary branches, plant height, siliquas per plant and seed yield per plant in four single crosses. Number of siliquas per plant were highly heritable coupled with high genetic advance and coefficient of variability. It reflected a great scope for selection. Cross combinations 86-4-3 x Poorbi Raya and 86-16-1 x Poorbi Raya were particularly valuable for various characters. They gave high heritability and genetics advance for most characters. Indicating that selection should lead to a fast genetic improvement of the material.

  Five cross of Brassica juncea viz., SMP 13-78 x Zem-I, SML 31E x Zem-I, DL 8 x Zem-I, SM 83000 x Zem-I, Pr 171-71 x Zem-I were made. These crosses (F1's) along with their parents were sown and heterosis was studied for branches per plant, plant height (cm), number of siliquas and yield per plant (g) in F1 generation. It was found that a cross of SMP 13-78 x Zem-I showed maximum heterosis and heterobeltotic for all the characters studied. Therefore, this cross combination can fruitfully be utilized for improving yield and its components in future breeding programmes.

  Eighteen lines/varieties of Brassica juncea L. were evaluated for plant height, number of branches plant-1, Number of siliquas plant-1, 1000 seed weight and seed yield plant-1 through PCV, GCV, h2, G.A., correlations and path coefficient analysis. Number of siliquas plant-1 found strong parameter followed by number of branches and Plant height for seed yield improvement. Siliquas plant-1 had highest GCV, h2, G.A., highly significant positive correlation and maximum direct contribution for seed yield followed by number of branches plant-1 and plant height.

  The present study was carried out to investigate the fillet composition of fresh water farmed Labeo rohita in relation to body size. For this purpose forty-five specimens ranged in total length from 15.6 to 31.5 cm and in weight from 36.82 to 350.17 g were collected from Government Fish Seed Hatchery Mian Channu during November 2001. After the removal of head, scales, fins and viscera, the remaining trunk (processing yield) was cut into fore, mid and hind fillets. Each fillet was dried and powdered for the analysis of dry mass, water mass, ash content, organic content (all on percentage basis). There was a good correlation between water content (%) and other constituents (% ash, % organic mass) of the processing yield. Body mass and total length significantly affect the processing yield and nutrient constituents. Equations were developed to describe the relationships between body constituents and body mass and length. ANOVA was applied to assess the difference among the body composition parameters. Significant differences were found in these fillets, which indicates the quantitative and qualitative nature of fillets for nutritive purposes.

  The present study was carried out to investigate chemical composition of gallstones and their presentation in patients of different age groups of human population in Multan, Pakistan for a period of 18 months from August 2001 to January 2003. Gallstones were diagnosed by ultrasound and ultra sonography specifically in gallbladder and in bile duct. After cholecystectomy gallstones were washed, dried and analyzed by infrared spectroscopic and chemical method for various bio-chemical components. Of the 303 cases of gallstones, 274 (90.42%) were in gall bladder and 29 (9.57%) were in the bile duct. The predominant symptoms associated with gallstones were pain in hypochondrium, 164 (54.12%), vomiting 54 (17.82%), nausea 30 (9.90%), fever 38 (12.54%) and fatty food 17 (5.61%). According to the chemical composition of the gallstones, most of the stones examined in this study were of cholesterol 86 (28.30%), calcium oxalate 53 (17.40%), calcium phosphate 21 (6.90%), pure uric acid 31 (10.30%), pure bile 55 (18.40%) carbonate + magnesium 33 (10.80%) and others 24 (7.90%) were of mixed lithiasis. Of these cases the incidence of formation of cholesterol stone, was maximum in all age groups of both sexes.

  The present study was carried out to assess prevalence of hepatitis B virus (HBV) in relation to sex, age, promotive factors, associated symptoms and season among human urban population of Multan, Pakistan for a period of 32 months from June 2001-February 2004. The present study was based on the data, collected randomly from the human population aging from 1-72 years. The population was divided into three age groups i.e old (age above 50 years), mature (age 13-50 years) and young (age below 13 years). The results from the present study suggested that among the observed urban population of Multan (n=2531), prevalence of HBV was 7.94%. The prevalence of HBV when studied in different age groups of both sexes, it was found that prevalence of HBV was maximum (9.63%) in mature males as compared to young males (6.14%) and old males (5.44%). The prevalence of hepatitis B surface antigen was higher (7.94%) in young females as compared to mature females (7.32%) and old females (6.80%). The main promotive factors for HBV were unscreened blood transfusion 56 (27.86%), infected syringes 34 (16.91%), contaminated barber, parlor tools 32 (15.92%), contaminated dentist equipments 29 (14.43%) and contaminated surgery equipment 25 (12.44%). The reported cases of HBV positive patients were maximum in summer 146 (72.63%) as compared to 55 (27.36%) in winter.

  Maize is sensitive to drought and suffers a serious setback in yield due to high temperature stress. There is need to evaluate maize inbred lines, which are resistant to drought conditions. Ten maize inbred lines namely MO-17, DK-656, lZI-7103, SYP-31, AYP-17, H-93, B-73, A-6660, IZI-4001 and KLI-2301 were exposed to water stress in drought chamber. Genotypic and phenotypic correlation coefficients of various plant morpho-physiological traits with grain yield were ascertained. Survival rate treat-II, root-shoot ratio, stomatal frequency and photosynthetically active rations showed significant correlation at genotypic level with grain yield. The study emphasized that these morpho-physiological traits have underlying genetic basis. Once these basis are understood precisely, breeders will be able to tailor maize varieties with better yield potential.

  Nutrients variation studies were conducted to understand the nutrient cycle (particularly nitrogen, phosphorus and cations) in four year old Acacia plantation ( Acacia nilotica and Acacia ampliceps) and the impact of salinity on nutrient cycling. Leaf samples were collected around the umbrella of 10 trees of each Acacia for nutrient content at the interval of two months. Soil salinity in the immediate proximity of the tree trunk was also monitored. Analytical results showed that both the species had adequate amount of nitrogen and phosphorus. Potassium was also near the critical levels. However, the Ca content was comparatively higher, which might be due to presence of organic acids during decomposition of organic residues present at the soil surface. Studies on monthly variation in mineral elements suggested that only single time period for sampling to study the nutrient status or scheduling time of fertilizer application is not appropriate. Therefore, the best time for studying nutrient status and fertilizer application would be during March-April or September-October, when the weather is mild and salinity is moderate.
