The study was conducted to evaluate 23 genotypes of marigold (Tagetes spp.) collected from different and diverse sources correlation studies were performed for various growth yield characters. results shows that the maximum plant height (92.60 cm) is recorded in genotype AMS-15, whereas spread (52.80 cm), flower weight (8.93 g) largest size (7.63 ‘AMS-16’. highest number branches (11.13), flowe...

A ?semigroup is a semigroup whose lattice of congruences is a chain with respect to inclusion. Schein 9] and Tamura 11] have investigated commutative ?semigroups, Trotter 13] exponential, Nagy 4] weakly exponential and Bonzini and Cherubini Spoletini 2] nite ?semigroups. The pupose of the present paper is to investigate archimedean weakly commutative and H?commutative ?semigroups. 1 Weakly comm...

Let x = (x1, . . . , xp) ′ ∼ N(0,Σ), where Σ is a p×p positive definite matrix. Assume that we have observed a sample of size n, (yi,xi) n i=1 and assume σ = 1. Consider simulating data by taking various combinations of (n, p,Σ,β) as follows: (a) n = 50, 500 (b) p = 100, 1000 (c) Σ = I,S0.1,S0.6 (d) casse (i) β1 = · · · = β5 = 3, βj = 0 for any other j; case (ii) β1 = · · · = β5 = 5, β6 = · · ·...
