Screening of drought tolerant wheat (Triticum aestivum L.) genotypes using stress tolerance indices and principle component analysis

As climate is changing and shortage of water resources takes place at alarming level wheat productivity is influenced at larger scale. Keeping this scenario in view, a field experiment was conducted at the experimental farm of Nuclear Institute of Agriculture (NIA), Tandojam, Pakistan, during Rabi season 2017-18. In this study, sixteen wheat genotypes were used […]

Combining ability and heritability estimation for elite genotypes in hexaploid wheat (Triticum aestivum L.)

Wheat breeders are also well known of the phenomenon that in a hybridization programmes, certain crosses pass-on more favorable genes towards the progenies than others. Thus, identification of potential parents and hybrids remained main concern to cotton breeders for improving various yield and biomass traits in wheat breeding programmes. Genetic inheritance pattern deals with the […]

Impact of foliar silicon application on yield attributes of wheat (Triticum aestivum L.) under water deficit environment

The consequences of climate change, particularly in the form of water deficiency are now evident in different parts of the world that negatively affecting the crop productivity. The current study was conducted to explore the involvement of exogenously applied silicon in reducing the negative effects of drought stress on yield of wheat. The wheat cultivar […]

Effect of varied seeding densities on growth, yield and yield attributes of different wheat (Triticum aestivum L.) genotypes of Pothohar region

Seeding density is a key factor that affects grain yield and quality of wheat. An indiscrimination in seeding density has been observed across the wheat growing areas of Pothohar region. Hence optimization of planting density of Pothohar wheat genotypes is vital to boost its yield in rainfed areas as well as in the country. It […]

Effect of varied seed rate on growth, yield and yield attributes of different wheat (Triticum aestivum L.) genotypes of Pothohar region

Seeding density is a key factor that affects grain yield and quality of wheat. An indiscrimination in seeding density has been observed across the wheat growing areas of Pothohar region. Hence optimization of planting density of Pothohar genotypes is vital to boost its yield in the country as well as in rainfed areas. It is […]

Synergistic effect of weeds extracts on growth parameters of three different cultivars of wheat crop (Triticum aestivum L.)

This study was designed to evaluate the synergistic effect of 6 different weeds (Chenopodium album, Avena sativa, Lathyrus sativus, Cirsium arvense, Rumex dentatus, and Phalarus minor) on the growth and related attributes of three cultivars (Faisalabad1, Sahar6 and Galaxy) of wheat (Triticum aestivum L.). Current study aims to exploit the allopathic potential of weeds on […]

Phenotypic association and heritability analysis in bread wheat (Triticum aestivum L.) genotypes

Development of new cultivars with high yield potential is one of the main objectives of most of the wheat improvement programs. In the current study a set of eight bread wheat genotypes were evaluated to determine phenotypic association and heritability analysis for some quantitative traits. Eight bread wheat genotypes were evaluated in a randomized complete […]

Generation mean analysis in wheat (Triticum aestivum L.) under water deficit stress condition, using mixed linear models

Drought stress is one of the most important factors reducing crop production in the world. Understanding the type and relative amount of genetic components is essential for determining the breeding methods for genetic improvement of drought tolerance related traits. In the present study, generation means and variances analyses were employed to estimate additive, dominance and […]

Polyphenol oxidase (PPO) activity during germination and early seedling growth of wheat (Triticum aestivum) and effect of seed size, abrasion and light on its activity

The most important widespread cereal is Wheat (Triticum spp) which is used throughout the world. An important problem for the flour and flour related products is their darkening and discoloration which is believed to result from polyphenol oxidase (PPO) activities. The most important enzyme responsible for browning of end product in wheat is Polyphenol oxidase […]

Efficacy of Inula viscosa extracts on seed germination and fungal infection of three varieties of wheat (Triticum aestivum L.)

The aim of the present investigation was to look for bioactive substances which may decrease the use of chemical pesticides to control seed borne fungi and thus protect the environment from an excessive chemicalization. In this study three concentrations (500, 1000 and 1500 ppm) of Inula viscosa extracts were tested for their efficacy in controlling […]
