Genetic variability, Heritability and Correlation Analysis in F2 Populations of Ratoon Upland Cotton Hybrids

Genetic variability, heritability, Genetic advance, correlation coefficient and path analysis in gladiolus

Gladiolus (Gladiolus floribundus L.) is a bulbous ornamental plant belongs to family Iridaceae. It is an elegant cut flower grown for its magnificent spikes. The estimates of heritability varied from 99.5% to 61.1%. The highest heritability estimates in broad sense was observed for the characters vase life (99.5%) and lowest for height at 30 days after planting. Expected genetic advance express...

High-density genetic linkage map construction by F2 populations and QTL analysis of early-maturity traits in upland cotton (Gossypium hirsutum L.)

Due to China's rapidly increasing population, the total arable land area has dramatically decreased; as a consequence, the competition for farming land allocated for grain and cotton production has become fierce. Therefore, to overcome the existing contradiction between cotton grain and fiber production and the limited farming land, development of early-maturing cultivars is necessary. In this ...

A 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, ...

Assessment of genetic variability, heritability and association of plant attributes with lint yield and fiber quality in advanced lines of cotton (Gossypium hirsutum L.)

Information on genetic variability and heritability of plant attributes and their correlation with lint yield and fiber quality is important for planning breeding and selection strategies for prediction of genetic gains in cotton breeding programs. For these purpose, a field experiment was carried out using randomized complete block design with four replications in 2016 and 2017 at Hashem-Abad ...
