There are numerous wild bees including cavity nesting and soil dwelling bees which play a significant role in crop pollination apart from honey bees. Bees are vital for pollination and nut set in cashew. By increasing the population of native bees, pollination can be enhanced,...

Thrips are minute insects, serve as pests on many crop plants. According to Tyagi et al. (2017), there are approximately 6102 described species of thrips globally, and about 1% of them have been reported as pollinators, predators, pests, or vectors of plant viruses. In&...

Helopeltis antonii Signoret (Miridae: Hemiptera), commonly known as tea mosquito bug (TMB) is a serious pest of cashew. Presently, insecticidal management is widely adopted for this pest and there is a need for non-chemical pest management strategy. Plants respond to the fe...

Thrips are the insects belonging to the insect order Thysanoptera. In cashew, thrips occur both on the leaves and flowers. Not all the thrips species are pests, some species are predaceous in nature, some are fungal spore feeders and a few are even pollinators. Common&#x...

The cashew apple makes up approximately 90 % of the weight of the cashew fruit and only 3.5 % of cashew apple is being used in commercial production, the remaining are left to rot and goes as waste. In the field conditions, insects help in decomposition of cashe...

Ant-plant associations are greatly diverse leading to mutualistic and/or antagonistic interactions between them. In general, ants are considered as minor pollinators. Ant pollination is rare and restricted to a few plant species. The cashew trees are consistently visited by diverse species&#...

Bees play a crucial role in pollination, ensuring the reproduction of many flowering plants, but there is growing concern over the decline of bee populations worldwide. Female conopid flies are parastioids that lay eggs in the bodies of aculeate Hymenoptera for example bees, and&#x...

CRISPR-Cas system provides a form of immune memory in prokaryotes and archaea, protecting them against viruses and foreign genetic elements. In Streptococcus pyogenes, this system includes the pre-crRNA along with another non-coding RNA, tracrRNA, which aids in CRISPR-based immunity. In S. p...

Once a minor disease, rice false smut, caused by Ustilaginoidea virens, has recently become one of the most important diseases in rice-growing areas of the world. In India, yield loss due to false smut reaches up to 49%, while in China, the average yield loss accounts...

Doubled haploid (DH) breeding is a powerful technique to ensure global food security via accelerated crop improvement. DH can be produced in planta by employing haploid inducer stock (HIS). Widely used HIS in maize is known to be governed by ZmPLA, ZmDMP, ZmPLD3, and ZmPOD65&#...

Rice, a staple food for a significant portion of the global population, faces persistent threats from various pathogens and pests, necessitating the development of resilient crop varieties. Deployment of resistance genes in rice is the best practice to manage diseases and r...

Rice production faces a significant threat from the rice leaffolder, Cnaphalocrocis medinalis. To address this challenge, grow ing resistant varieties stands out as a sustainable and eco-friendly pest management strategy. This necessitates identifying resistant sources and understanding their&...

Drought is one of the major abiotic stress factors affecting the growth and production of rice globally and it can cause an estimated yield loss up to 90% in rice. With the increasing population around the globe, a comprehensive approach for mitigating drought stress &#x...

A path to sustainably reduce world hunger, food insecurity, and malnutrition is to close the crop yield gap and, particularly, lower losses due to pathogens. Breeding resistant crops is key to achieving this goal, which is an effort requiring collaboration among stakeholder...

Rice blast disease is the most devastating disease constraining crop productivity. Vertical resistance to blast disease is widely studied despite its instability. Clusters of genes or QTLs conferring blast resistance that offer durable horizontal resistance are important in resistan...

Improving desirable traits of popular rice varieties is of particular importance for small-scale food producers. Breeding is considered the most ecological and economic approach to improve yield, especially in the context of pest and pathogen-resistant varieties development. Being able to&...

The unpolished whole rice grains having the pericarp intact are packed with nutrients and antioxidants. The colored pericarp provides health benefits against lifestyle diseases. The diversity in the pericarp color which can be red, brown or black in various shades is a refle...

Bakanae disease in non-basmati indica rice is emerging as a major threat owing to climate change. Our objective was to identify quantitative trait loci (QTL)/gene(s) in Thavalakannan, responsible for bakanae disease resistance. A bi-parental population was developed between a resistan...

BACKGROUND: High resistant starch (RS) rice with a low glycemic index (GI) is digested more slowly, resulting in a slow increase in the postprandial blood glucose level. People with milled rice as a staple diet, and with sedentary lifestyles, are more prone to acquire&#...

The population growth and the regular breakout of Nilaparvata lugens pose a significant risk to rice cultivation. Four different N. lugens biotypes have been identified worldwide, with biotype 4 being the most destructive and prevalent throughout Asia, particularly in India. The...

A crucial phenotypic attribute for breeding rice for direct seeded condition is rapid uniform germination and build-up of biomass during the initial period of seedling establishment. Seed vigour constitutes such traits that have gained potential to meet the requirements of breed...
