Consumer perception of fair trade: a cross-cultural study
The term of fair trade basically explains the fair exchange of goods and money between producer and consumer without ignoring the quality and price balance. The fair trade concept gains an importance by globalisation; the basic idea is to protect local production. The most well-known fair trade products are the agro-cultural ones like coffee, cacao and cotton, which are usually produced in ...

A target region amplified polymorphism marker for fertility restorer gene rf1 and chromosomal localization of rf1 and rf2 in cotton
Cytoplasmic male sterility (CMS), a maternally inherited trait characterized as an inability to produce functional pollen, is an important biological system for economically producing hybrid seed to enhance crop yield and studying cytoplasmic and nuclear gene interactions. In cultivated tetraploid cotton (Gossypium hirsutum L.), male fertility in two systems CMS-D2 and CMS-D8 is restored by two ...

Impact of heterozygosity and heterogeneity on cotton lint yield stability
In the last 8 yr, cotton (Gossypium hirsutum L.) growers in North Carolina have experienced variations in the year-to-year lint yield averages that range from a 56% increase to a 49% decrease. This variability results in wild fluctuations in income and a desire for more stable yields. Genetic structure may contribute to stability. This study was conducted to determine the impact of heterozygosity ...

A comparison of three isolines of cotton differing in fiber color for yield, quality, and photosynthesis
Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are eco-friendly for the textile industry because they omit the dyeing process and reduce harmful effluent liquor. However, the low yield and quality of CCFs have greatly affected their development. Limited information is available on the reasons for the low yield and quality of CCFs. The aim of this 2-yr investigation was to compare ...
