By a resolution of t-designs we mean a partition of the trivial design ? X k of all k-subsets of a v-set X into t ? (v 0 ; k;) designs, where v 0 v. A resolution of t-designs with v = v 0 is also called a large set of t-designs. A Room rectangle R, based on ? X k , is a rectangular array whose non-empty entries are k-sets. This array has the further property that taken together the rows form a ...

Genotype-environment interaction for plant breeders has been important as it is a complex issue in breeding for high yield varieties and releasing new genotypes. In order to assess adaptability and stability of sunflower varieties in different climate conditions, twelve cultivars were investigated in Karaj, Shiraz, Birjand, Kashmar and Arak in randomized complete block designs with three replic...

this experiment was conducted to evaluate rate and duration of grain filling among old, modern and promising rice cultivars under different nitrogen levels in fields of  sari agricultural sciences and natural resources university, during 2008. two factors consisted of different urea fertilizer (0, 100 and 200 kg ha-1) as main plot and four promising lines (jelodar, partou, danesh and jahesh), 2...

In order to evaluate the yield, yield components and protein contents of two wheat cultivars (Zarrin and Gaspard) in sole cropping and intercropping systems,an experiment was conducted using replacement serious technique and different combinations of intercropping with high plant density and optimal of each cultivar. A factorial experiment was conducted in the form of randomized complete block ...

In this article, we investigate 2- $$(v,k,\lambda )$$ designs with $$\gcd (r,\lambda )=1$$ admitting flag-transitive automorphism groups G. We prove that if G is an almost simple group, then such a design belongs to one of the eight infinite families 2-designs or it eleven well-known examples. describe all these examples designs. We, in particular, $${\mathcal {D}}$$ symmetric (k,\lambda group ...

Abstract The evaluation of the yield stability of genotypes and environment is of prime concern to plant breeders. Therefore, a comprehensive analysis of the structure of the GE interaction is needed. The objective of this investigation was to evaluate the use of sites regression (SREG) GGE methodology to stratify the pe × environment (GE) interaction in lentil. Yield data of 10 genotypes of le...

In order to determine the best index for evaluating maize genotypes, 28 maize hybrids were evaluated in two planting dates, 6 July to coincide heat stress with pollination time and 27 July as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in Shushtar city, in 2008. Results showed that in st...
