Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...
Grain yield of bread wheat (Triticum aestivum L.) is reduced by heat stress, particularly when occurs in reproductive phase, in many countries worldwide, including Iran. In order to study the effects of different levels of nitrogen and cytokinin on wheat yield and yield components at normal and heat stress conditions in Khuzestan, Iran, this research was conducted at Ramin Agriculture and Natur...
In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

Dry seeds of seven winter wheat varieties and one line were exposed by gamma-rays and chemical mutagens to determine their effect on plant grows and development. Next parameters have been investigated – plant survival, pollen fertility, components of yield structure. Informative value by mutation depression evaluation of all parameters has been developed. The most informative parameters for mut...
The presented study analyzed the inheritance via heterosis of interspecific F1 hybrids between durum and bread wheat over better parents ratios dominance for spike-related traits affecting their productivity transmission to future segregating populations. research transpired in crop seasons 2017–-2019 at Institute Molecular Biology Biotechnologies, Azerbaijan National Academy Sciences, Baku, Az...
The aim of this study was to determine nature and extent of variability parameters and their utilization in barley breeding programme. A total of 45 F1s along with their parents and F2 populations were evaluated in a randomized block design with 3 replications during Rabi (winter season) 2014. The various traits measured were days to 50% flowering, days to maturity, plant height, flag leaf area...
The current study was undertaken to analyze the genetic variability, correlation and path for yield its attributing traits at agriculture research farm, Department of Genetics Plant Breeding, School Agriculture, Lovely Professional University, Punjab during Rabi 2021-22 2022-23. Augmented design with F2 seeds planted in ear row fashion 4 rows were used including 2 parent 6 F2’s 9 viz. plant hei...

Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...
