If your grammar is CLR(1) then it is not necessary that it is LALR(1) but if Grammar is LALR(1) then it will Definetly be CLR(1)

if grammer is CLR(1) then it necessarily LALR(1) ? - Not necessarily True
and IS reverse also true ? reverse is always True, every LALR(1), SLR(1) and LR(0) grammar are CLR(1).
and is LR(1) short form for CLR(1) parser ? - No it is not
