  • In this paper, diallel crosses block designs for control versus test comparisons among the lines are proposed. These block designs are constructed by using partially balanced incomplete block designs with C-properties. Also, the efficiencies of the diallel crosses block designs obtained through this method are tabulated for number of lines 22 or less.

  • Ten anther-derived doubled haploid (ADH) and 10 maternally-derived doubled haploid fines (MDH) from NC 2326 were evaluated in the field to compare their performance. Both anther-derived doubled haploid and maternally-derived doubled haploid lines were agronomically inferior to selfed parental variety for many parameters, but the degree of inferiority of the MDH lines were not significantly different from the selfed parental variety for any character investigated. The inferiority of the ADH lines were, however, significantly different from the selfed parental variety for yield, leaf length and width , and days to flower.

  • In this paper, a method based on group divisible designs is presented for constructing some partial diallel crosses. We discuss in detail a particular inbred line, i.e., p lines divided into two groups with p$_1$ lines and p$_2$ lines. These designs are obtained by regarding the number of lines as treatments. In specially we study and compare the efficiency factors of the constructed partial diallel crosses with or without repeated blocks.

  • Currently, the technique of pronuclear microinjection is the most successful and most widely-used method for producing transgenic animals. Among this technique, surperovulation and embryo transfer are the crucial steps for obtaining a large number of fertilized eggs and birth as much as potential founders from the transferred embryos.
