hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...

The original problem of phyllotaxis was focused on the regular arrangements of leaves on mature stems represented by common fractions such as 1/2, 1/3, 2/5, 3/8, 5/13, etc. The phyllotaxis fraction is not fixed for each plant but it may undergo stepwise transitions during ontogeny, despite contrasting observation that the arrangement of leaf primordia at shoot apical meristems changes continuou...

One hundred upland cotton germplasm accessions were evaluated for eight traits to evaluate the per se performance, genetic variability, heritability, advance as a cent of mean, correlation and path analysis. The estimation variability indicated that number monopodia plant had high GCV PCV. High heritability along with GAM was  found in height, internode length, plant, sympodia bolls seed y...

Much attention has shifted to the effects of temperature and solar radiation on rice production grain quality due global climate change. Meanwhile, lodging is a major cause yield losses. However, responses resistance are still unclear. To decipher mechanisms through which might be affected by radiation, 32 cultivars with different were grown at two eco-sites three sowing dates over period years...

Background . Lodging resistance of winter rye is associated with morphological features the stem. Searching for source material to breed non-lodging high-yielding cultivars requires studying varietal phenotypic diversity according characters stem that affect lodging and productivity ear. Materials methods Experiments were carried out in 2017–2020 at Federal Agricultural Research Center North-Ea...

carbon dioxide is the most important resource for crop growth. in order to investigate the effect of elevated co2 concentration on morphological and physiological characteristics of sesame (sesamum indicum l.) and amaranthus (amaranthus retroflexus l.) an experiment was conducted in greenhouse conditions. the experiment was factorial based on randomized complete block design with six treatments...

Incomplete panicle exsertion in almost all the WA-based CMS lines is one of the major impediments in obtaining higher seed yield in hybrid rice breeding programs. Exploitation of Elongated Uppermost Internode (eui) mutants in rice is a viable genetic strategy to solve this problem. Present study was undertaken with an aim of characterizing the elongated uppermost internode mutants in rice germp...
