I am very confused about the use of term cultivar or variety for same genotype in different papers. Which should be used more accurately?
Cultivar is a popular genotype and being cultivated widely. It may be a variety, an advance line, strain or land race (recommended or non-recommended). However, variety is a group of plants having distinct, uniform and stable traits which has been recommended for cultivation by a committee.
Maybe this can help clarify the terms: http://www.ipm.iastate.edu/ipm/hortnews/2008/2-6/CultivarOrVariety.html
Now a days rice cultivar is in use. but cultivars are not of true to type as varieties.
Cultivar is any genotype under cultivation, it may be variety, advanced breeding line, land race (recommended or non-recommended).
Variety is group of plant having specific uniform chracteristics recommended for cultivation for general and specific area by a committee.
There are many promising varieties of rice are available but it depends on cultivation practices and geographical areas where some specific var. are more suitable for its better production
Cultivar means Cultivated variety. There is no difference between two in practical usage.

Cultivar means cultivated variety, which is genotype under cultivation; it may be variety, advanced breeding line, land race.These cultivar or varieties when used in research program term were changed it’s depend on objective. Ex. 1) if these used in crossing programme for combining ability analysis said as parents 2). In segregating population as in F2 or Advance generation each plant treated as single genotypes (each having different allelic combination).3). F6 onwards treated as Lines (group of uniform plant having almost same allelic combination).4). In resistant breeding prog. Said as strain.
As much as i read the books there is no clear cut demarcation i found about these terms.
Generally 'variety' is considered to a taxonomic rank below species, whilst cultivar is used to denote a plant bred for agriculture or horticulture.
There is no real agreement as to whether the correct term in taxonomy is 'variety' or 'subspecies', it depends on which authority one is using. The two are often used interchangeably in the literature. There are even instances of confusion between 'variety/subspecies' and 'cultivar' although this is less common.
A good rule of thumb: If you are talking about wild rice genotypes use variety, and when talking about bred rice genotypes use cultivar.
Hope this helps!
Any variety which is presently under cultivation is called cultivar.
In simple terms a variety is a type of plant that arose in nature while a cultivar is the result human intervention. The human intervention may be slight such as just collecting the plant or its seeds but the existence of the plant is due to human effort. The term cultivar is especially useful to horticulturalists in their need to produce and market new (and hopefully better) plants.
