Genetic variability for seed cotton yield and itscomponents were studied in three segregating F2 populations of (Gossypium hirsutumL.). Significant variation was recorded major traits all the populations. Traits such as plant height (20 cm to 143 cm), bolls per (1 30), boll weight (2.0 g 6.8 g) (1.8 115 exhibited wide range.High PCV GCV estimates under study except days 50 cent flowering openin...

It is still not clear whether differential response of Bt cotton and conventional non-Bt genotypes in terms growth, phenology yield ability are hypothetical or realistic. This study investigated the three hybrids comparison to their non-transgenic version (near-isogenic lines) along with two locally adapted for attributes, phenological characteristics rooting behavior. Therefore, experiments we...

The Turkestan region is a cotton-growing zone in South Kazakhstan, but also the northernmost area world. Annually, medium-staple cotton (Gossypium hirsutum L.) cultivation occurs on 115,000–125,000 ha, with 80,000–85,000 ha grown Districts of Maktaaral and Zhetysay, Kazakhstan. This highly susceptible to salinity, drought, invasion dangerous pests (cotton budworm, beet borer, spider mites, aphi...

Background: water shortage is one of the major factor effects on growth characters and yield most crops. Objective: this study was conducted to get know reactions some Egyptian cotton genotypes deficit. Methods: The genetic materials used in included thirteen belonging Gossypium barbadense L., from Cotton Research Institute (CRI), which devoted establishing experimental for investigation. Resul...
