The success of DH technology dependents on the efficacy of optimized protocol that could be utilized for large scale production of homozygous lines. In this study, anther culture protocol was established using invitro colchicine treatment of haploid callus derived from anthers of niger (Guizotia abyssinica L.F. cass). Flower buds at uninucleate sta...

To keep pace with the skyrocketing demand of vegetable oil and reduced dependency on import, there is a need to focus on indigenous oilseed crops, such as niger (Guizotia abyssinica L.F. Cass). Niger is a minor oilseed crop that consists of 32 to 40% quality oil and 18 to 24% protein in the seeds. Despite its considerable importance, self-incompati...

The present study was conducted to induce polyploidy through colchicine treatment to obtain better yield by enhancing the vigour, improving morphological and yield attributing traits. The Niger seeds were exposed to four different colchicine concentrations (0.025,0.05,0.1 and 0.2%) at different time duration (6, 16, 24 and 48 hrs.). The experiment...

The present study was conducted to determine the response of 55 double haploid (DH) rice lines developed for drought tolerance from the cross Swarna × IR159B in polyethylene glycol (PEG) induced drought stress under in-vitro conditions (DH lines named as double haploid rice lines-DRL). Drought stress was created using PEG-6000 at different level of...

In the past few decades, in vitro selection based on tissue culture techniques has developed as a useful tool for improving biotic as well as abiotic stress tolerance in crops. Rice is a staple crop and is susceptible to drought and salt stress. Tolerance can be acquired in vitro by using selection agents such as polyethylene glycol, mannitol, sali...

Bamboo is an economically important member of the grass family Poaceae with over 1500 documented uses. India has the 2nd largest reserve of bamboo in Asia after China. It is also called “Poor man’s timber”, “Green Gold” and “twenty-first century steel”. They are extensively used as raw material for various industries besides serving the rural popul...

The experiments were conducted during kharif (June to September) 2018 and 2019 to screen 7 aromatic rice double haploid (DH) lines developed against Bacterial Leaf Bligh (BLB) and blast disease. Three genes Xa21, xa13, xa5 for BLB resistance and two genes Pi1, Pi2 for blast resistance was introgressed into a local aromatic rice variety Dubraj f...

Rice is a staple food crop for more than half of the world's population, supplies adequate energy in the form of calories. However, it is a poor source of proteins, minerals such as iron and zinc that are essential to human health. Increasing nutritive values of rice grains is one of major breeding objectives of improving rice to provide a solution...

Despite steady improvement in oilseeds production, there is a yawning gap between demand and supply of edible oil leading to dependence on imports. To reduce the import dependency, a speedy recourse is necessary to boost indigenous edible oil sector. There is a need for increased production of edible oil from minor oilseed crops such as Niger (Guiz...

The physiological, genetic and molecular mechanisms of metal homeostasis related genes need to be characterized from a bio-fortification perspective and should be well integrated with the breeding processes. Out of 43 genes related to metal homeostasis, transcript of OsZIP10 gene found to be associated with grain zinc content in rice. OsZIP10 gene...

To understand the role of metal homeostasis-related genes in rice, micronutrient levels of different tissue types were analysed at mid grain-filling stage followed by the expression analysis of candidate genes in these tissues. Subsequently, the association between the gene expression pattern and micronutrient level in tissues as well as mature gra...
