3.The method of path coefficient analysis was used to study the direct and indirect effects upon the grain weight per plant from eight characters of seedrows per ear, seed number per row, hundred grain weight, ear length, ear diameter, plant height, ear height and ear height X ear diameter; meanwhile, such heredity parameters as the correlation coefficient, variation coefficient, path coefficient and the broad heritability erc.
7.One hundred and eighty Wulong geese of fast-growth line (FGL) and egg-production line (EPL) were selected to be fattened in netting bed respectively. The weight of each goose was measured, feed consumption and feed conversion ratio were determined at the same time, serum enzyme activities at the age of 6 and 10 week were carried out respectively, and the correlation between serum enzyme activity and weight of the goose was also analyzed.
8.s One hundred and fifty seeding plants constructing the population for marker analysis on gene linked to sugarcane smut resistance were studied. The results show that the variation coefficients for six main economic characters of height, diameter, brix, stalk number, stalk weight and brix weight are from 9.92% to 39.68%,in which the maximum variation coefficient is found in stalk weight of clump and the minimum is found in brix.
9.One thousand two hundred and eight-six childbearing age women taking 18-methylnorethindrone compound were investigated, and the eight side effects such as early pregnancy reaction, hypomenorrhea, leukorrha-gia and increase of weight were analysed according to the years of administration, occupation, age and the number of the children.
10.One hundred "Duroc ×Landrace×Yorkshire" crossbred weanling piglets(26±2 days of age) were randomly divided into 5 groups with 20 piglets each by weight and sex,fed with basal diet,basal diet plus(2 000) or 3 000 mg·kg~(-1) zinc(from ZnO),and basal diet plus 250 or 500 mg·kg~(-1) zinc(from Zn-Met),respectively.
