genetic studies in upland cotton (gossypium hirsutum l.) ii. general and specific combining ability
the present experiment was carried out to assess the general combining ability (gca) and specific combining ability (sca) of six important commercial cultivars of gossypium hirsutum l. of venezuela, viz., ‘deltapine 16’, ‘tamcot-sp-21’, ‘cabuyare’, ‘stoneville’, ‘ospino’ and ‘acala 90-1’ and their 15 f1 hybrids, respectively. the data were analyzed using griffing’s model i method ii. significan...
متن کاملQTL analysis for early-maturing traits in cotton using two upland cotton (Gossypium hirsutum L.) crosses
Making use of the markers linked closely to QTL for early-maturing traits for MAS (Marker-assisted selection) is an effective method for the simultaneous improvement of early maturity and other properties in cotton. In this study, two F2 populations and their F2:3 families were generated from the two upland cotton (Gossypium hirsutum L.) crosses, Baimian2 × TM-1 and Baimian2 × CIR12. QTL for ea...
متن کاملIn Vitro Cadmium-Induced Alterations in Growth and Oxidative Metabolism of Upland Cotton (Gossypium hirsutum L.)
Cadmium (Cd) is a toxic pollutant, which cause both dose- and time-dependent physiological and biochemical alterations in plants. The present in vitro study was undertaken to explore Cd-induced physiological and biochemical changes in cotton callus culture at 0, 550, 700, 850, and 1000 μM Cd for four different stress periods (7, 14, 21, and 28 days). At 1000 μM Cd, mean growth values were lower...
متن کاملMining and Analysis of SNP in Response to Salinity Stress in Upland Cotton (Gossypium hirsutum L.)
Salinity stress is a major abiotic factor that affects crop output, and as a pioneer crop in saline and alkaline land, salt tolerance study of cotton is particularly important. In our experiment, four salt-tolerance varieties with different salt tolerance indexes including CRI35 (65.04%), Kanghuanwei164 (56.19%), Zhong9807 (55.20%) and CRI44 (50.50%), as well as four salt-sensitive cotton varie...
متن کاملCharacterization and Functional Analysis of PEBP Family Genes in Upland Cotton (Gossypium hirsutum L.)
Upland cotton (Gossypium hirsutum L.) is a naturally occurring photoperiod-sensitive perennial plant species. However, sensitivity to the day length was lost during domestication. The phosphatidylethanolamine-binding protein (PEBP) gene family, of which three subclades have been identified in angiosperms, functions to promote and suppress flowering in photoperiod pathway. Recent evidence indica...
