Article Synopsis
  • Egyptian clover (Berseem) is a key winter fodder crop in India, essential for farm productivity and farmers' income, influenced heavily by the quality of seeds used.
  • The study reveals a rise in breeder seed (BS) demand until 2012-13, followed by a declining trend, despite a variety of cultivars being available for farmers.
  • It highlights challenges in BS production and suggests that maximizing seed chain efficiency could significantly increase coverage for cultivation in the coming years.

The current scanty knowledge about the salt tolerance mechanism underlying the ability of plants to tolerate salt stress hinders the potential production of numerous crops, including Indian mustard. To explore the traits and mechanism for salt tolerance, high throughput phenotyping of 250 stabilized F recombinant inbred lines (RILs) mapping population of Indian mustard were conducted under control and salinity (EC 12 dS m ) for 54 morpho-physio-seed-quality traits. Most of the traits were reduced with variable percentages under salt stress.

Lucerne ( L.) is the second most significant winter leguminous fodder crop after berseem in India. Breeder seed (BS) is the first stage of the seed production chain, as it is the base material for producing foundation and certified seeds.

Article Synopsis
  • Vitamin E deficiency can lead to various neurological issues, and while maize hybrids with a favorable vte4-allele are rich in α-tocopherol, their effectiveness is compromised during storage due to tocopherol degradation.
  • The study focused on the impact of the lipoxygenase enzyme and the LOX3 gene on tocopherol retention in two maize inbreds over six months, revealing significant tocopherol loss, with one inbred (HKI323-PVE) showing better retention correlated with lower lipoxygenase activity and LOX3 expression.
  • The findings suggest that HKI323-PVE, with its higher tocopherol retention and lower enzymatic degradation, could be a valuable resource for improving vitamin E

Crop Brassicas contain monogenomic and digenomic species, with no evidence of a trigenomic Brassica in nature. Through somatic fusion ( + ), a novel allohexaploid trigenomic Brassica (H1 = AABBSS; 2 = 60) was produced and used for transcriptome analysis to uncover genes for thermotolerance, annotations, and microsatellite markers for future molecular breeding. Illumina Novaseq 6000 generated a total of 76,055,546 paired-end raw reads, which were used for assembly, resulting in the development of 486,066 transcripts.

Market class, cooking time, quality, and milled grain yield are largely influenced by the seed size and shape of the lentil ( Medik.); thus, they are considered to be important quality traits. To unfold the pathways regulating seed size in lentils, a transcriptomic approach was performed using large-seeded (L4602) and small-seeded (L830) genotypes.

This study reports the identification of a unique lentil ( Medik.) genotype L4717-NM, a natural mutant (NM) derived from a variety L4717, producing brown, black, and spotted seed-coat colored seeds in a single plant, generation after generation, in different frequencies. The genetic similarity of L4717 with that of L4717-NM expressing anomalous seed-coat color was established using 54 SSR markers.

Tocopherol is vital for the nutritional value and stability of Indian mustard ( L. Czern and Coss) oil; nonetheless, the lack of information on genetic control is hampering its improvement. In this study, six populations (P, P, F, F, BCP, and BCP) of RLC3 × NPJ203 were evaluated in a family block design to evaluate the inheritance pattern, gene effects, and various other genetic parameters of tocopherol content (α, γ, and total), using generation mean analysis.

Microgreens have been used for raw consumption and are generally viewed as healthy food. This study aimed to optimize the yield parameters, shelf life, sensory evaluation and characterization of total aerobic bacteria (TAB), yeast and mold (Y&M), Escherichia coli, Salmonella spp., and Listeria spp.

Article Synopsis
  • - The study focuses on Ethiopian mustard's ability to withstand drought conditions, particularly emphasizing the development of new lines that combine traits from different mustard varieties to enhance drought tolerance and water efficiency.
  • - A total of 105 hybrids were evaluated for seed yield and related traits under both irrigated and rainfed conditions, revealing that non-additive gene actions play a significant role in productivity, especially under water deficit scenarios.
  • - Results indicated that certain hybrids showed significant advantages in yield potential and water use efficiency compared to their parental lines, suggesting effective selection methods (like Drought Tolerance Index) for breeding drought-resistant mustard varieties.

The Brassica coenospeceis have treasure troves of genes that could be beneficial if introgressed into cultivated Brassicas to combat the current conditions of climate change. Introducing genetic variability through plant speciation with polyploidization is well documented, where ploidy augmentation of inter-generic allohexaploids using somatic hybridization has significantly contributed to genetic base broadening. is a member of the Brassicaceae family that possesses valuable genes, including genes conferring resistance to , , pod shattering, heat, and drought stress.

Malnutrition has emerged as one of the most serious health issues worldwide. The consumption of unbalanced diet poor in nutritional quality causes malnutrition which is more prevalent in the underdeveloped and developing countries. Deficiency of proteins, essential amino acids, vitamins and minerals leads to poor health and increased susceptibility to various diseases, which in turn lead to significant loss in Gross Domestic Product and affect the socio-economic structure of the country.

Brassica mustard species represent one of the most important oilseed crops in India, nevertheless, their genetic diversity is barely known. A better understanding on this topic is essential for the proper utilization of genotypes in breeding programmes. We evaluated the genetic diversity among 44 Indian mustard (Brassica juncea) genotypes including varieties/purelines from different agro-climatic zones of India and few exotic genotypes (Australia, Poland and China).
