the mode of inheritance of seedling color and plant pubescence was studied in two crosses among three parents, which differed for these traits. the results have revealed that purple seedling color was dominant over green seedling color and pubescence was dominant over nonpubescence. these two traits segregated independently of each other may be used as morphological markers individually for dif...

This study aimed to identify promising crosses generate cowpea breeding populations for the Brazilian Cerrado region. The experiment was carried out during two crop seasons. experimental design used a randomized block with four replications and 20 genotypes prostrate. effect of significant all traits evaluated. Mahalanobis distance Tocher’s cluster were estimate genetic diversity. Singh’s crite...

Seed set is usually low and differs for different crosses of flower lotus (Nelumbo nucifera Gaertn.). The reasons remain unknown, and this has a negative impact on lotus breeding. To determine the causes, we carried out two crosses of flower lotus, that is, "Jinsenianhua" × "Qinhuaihuadeng" and "Qinhuaihuadeng" × "Jinsenianhua" and pollen viability, pistil receptivity, and embryo development we...

Size matters, particularly in demonstrations. A demonstration is in support of a movement or a cause. The movement has a number of sympathisers. The perceived number of sympathisers is important. If it is seen to be large, then it becomes easier to recruit others to the cause, and to persuade inactive sympathisers to join the demonstrations. Also, if the movement numbers are large then it is mo...

Wolves from the Great Lakes area were historically decimated due to habitat loss and predator control programmes. Under the protection of the US Endangered Species Act, the population has rebounded to approximately 3000 individuals. We show that the pre-recovery population was dominated by mitochondrial DNA haplotypes from an endemic American wolf referred to here as the Great Lakes wolf. In co...

Gilts were the progeny of eight Duroc, nine Meishan, eight Fengjing, and seven Minzhu boars mated to composite (1/4 Chester White, 1/4 Landrace, 1/4 Large White, and 1/4 Yorkshire) females. Age at puberty was youngest (P < .05) for Meishan and Fengjing crosses followed by Minzhu crosses and then Duroc crosses. Fengjing crosses had a higher (P < .05) ovulation rate than Meishan or Minzhu crosses...

previous communication ( MEE and LEE 1967) described the use of two-point A crosses in a transduction analysis of histidine requiring mutants of PseurEomonas aeruginosa. It was shown that histidine biosynthesis is controlled by at least five genes or groups of genes which have been designated his I, his 11, his 111, his IV and his V. However, no fine structure mapping has been carried out in Ps...
