Advancements in the internet technology front Advancements in the internet technology front have expanded the potential for Statistical have expanded the potential for Statistical Software.Software.

An online software allows researchers quick An online software allows researchers quick and convenient work environment.and convenient work environment.

Further, web based applications needs to Further, web based applications needs to exchange the information with each other. exchange the information with each other.

So, it is required to develop web services to So, it is required to develop web services to allow different statistical web applications to allow different statistical web applications to talk to each other, share services among talk to each other, share services among themselves.themselves.

The breeding experiments for plants and The breeding experiments for plants and animals involve two types of designs, namelyanimals involve two types of designs, namely (1) Mating designs(1) Mating designs (2) Environmental designs.(2) Environmental designs.

Diallel and partial diallel cross plans are two of Diallel and partial diallel cross plans are two of the commonly used mating designs.the commonly used mating designs.

Keeping in pace with the advancement in the Keeping in pace with the advancement in the statistical software technologies, there is need statistical software technologies, there is need to develop web based software in agriculture to develop web based software in agriculture research also.research also.

In a complete diallel cross (CDC) plan, as the In a complete diallel cross (CDC) plan, as the number of lines increases, the number of number of lines increases, the number of crosses increases rapidly resulting in difficulty crosses increases rapidly resulting in difficulty to handle all of them effectively.to handle all of them effectively.

Hence, it is always desirable to go for a sample Hence, it is always desirable to go for a sample of all possible crosses, which is known as of all possible crosses, which is known as partial diallel crosses (PDC).partial diallel crosses (PDC).

There are many different ways of approaching There are many different ways of approaching the problem of sampling a diallel cross.the problem of sampling a diallel cross.

In one, the association schemes of a partially In one, the association schemes of a partially balanced incomplete block (PBIB) design are balanced incomplete block (PBIB) design are used in constructing the PDC plans.used in constructing the PDC plans.

The second approach involves developing a The second approach involves developing a PDC based on circulant structure.PDC based on circulant structure.

Third approach for sampling the diallel cross, Third approach for sampling the diallel cross, the average variance over all the comparisons the average variance over all the comparisons is minimized.is minimized.

Packages available for generation and analysis Packages available for generation and analysis of partial diallel crosses are either stand-alone of partial diallel crosses are either stand-alone applications or are based on circulant plans.applications or are based on circulant plans.

The packages like SPSS, SAS, etc. can be used The packages like SPSS, SAS, etc. can be used for carrying out analysis but do not provide for carrying out analysis but do not provide layout plans of PDC.layout plans of PDC.

A web based software is required for A web based software is required for generation and analysis PDC plans based on generation and analysis PDC plans based on the association schemes of PBIB designsthe association schemes of PBIB designs
