The present investigation involved the estimation of the general combining ability of complete diallel crosses (CDC) plans with unequal numbers of crosses, subject to the unavailability of one block for Griffing's system IV . Further, it has been shown that CDC plans with unequal numbers of...

Dey & Midha (1996) showed that some of the complete diallel crosses plans, obtained by using triangular partially balanced designs with two associate classes, are optimal. In this investigation, it is derived that these optimal designs for diallel crosses are robust also against the...

The present investigation involved the estimation of the general combining ability of CDC plans subject to the unavailability of one block for Griffing's system IV. Further, it has been shown that CDC plans are fairly robust to the unavailability of one block.

Balanced incomplete block design (BIBD) with repeated blocks is studied in detail. Methods of construction of BIB designs with repeated blocks are developed so as to distinguish the usual BIBD and BIBD with repeated blocks. One additional parameter, say d, is considered here, where d denotes the...

Kane has discussed a simple method for identifying the confounded interactions from 2n factorial experiments when a replication consists of (1) two blocks and (2) more than two blocks. It should be noted that Kane's method holds only for (1) regular design and (2) when one interaction is...

The present investigation involves the methods of construction of complete diallel cross plans using balanced incomplete block (BIB) designs. Furthermore, the analysis of complete diallel crosses plans are carried out to estimate the general combining ability of the ith line (i=1, r 2, r …, r...

In this investigation, general efficiency balanced (GEB) and efficiency balanced (EB) designs with (v + t) treatments, using (i) balanced incomplete block (BIB), (ii) symmetrical BIB, (iii) f -resolvable BIB, (iv) group divisible (GD) and (v) resolvable GD designs have been constructed with...
