Heterosis and correlation in interspecific and intraspecific hybrids of cotton.
Interspecific and intraspecific hybrids show varying degrees of heterosis for yield and yield components. Yield-component traits have complex genetic relationships with each other. To determine the relationship of yield-component traits and fiber traits with seed cotton yield, six lines (Bt. CIM-599, CIM-573, MNH-786, CIM-554, BH-167, and GIZA-7) and three test lines (MNH-886, V4, and CIM-557) ...
متن کاملA Hairy Anther Mutant Isolated in Interspecific Hybrids between Upland Cotton and Pima Cotton
Plant hairs (trichomes) including cotton fiber develop from single epidermal cells on the aerial surfaces of plants. Two main types of trichomes, glandular and nonglandular, can be found playing various functions including protection from insect damage. The development of plant trichomes provides an excellent system for studies of cell developmental biology. Because they are easily observable, ...
متن کاملInterspecific Hybrids
The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...
متن کاملHistological Observations of Rotylenchulus reniformis on Gossypium longicalyx and Interspecific Cotton Hybrids.
Observations on the development of reniform nematode (Rotylenchulus reniformis) on roots of Gossypium longicalyx, G. hirsutum, and two interspecific hybrids derived from them were made by light microscopy. Gossypium longicalyx is reported to be immune to reniform nematode, but the mechanism(s) for resistance are unknown. Penetration of G. longicalyx roots by female nematodes was confirmed, and ...
متن کاملMeiotic behavior of interspecific hybrids
The meiotic behavior of four interspecific promising hybrids was evaluated by conventional cytological methods. The female genitors were two artificially tetraploidized sexual accessions of B. ruziziensis (R41 and R44, 2n = 4 χ = 36), which were crossed to an agronomically superior natural tetraploid apomictic genotype of B. brizantha (B140 BRA003395). Three of them (HBGC313, HBGC 315, and HBGC...
