In wheat endosperm, mannan, is poorly documented. Nevertheless, this hemicellulosic polysaccharide might have a determinant role in wheat grain development since, in Arabidopsis thaliana, mutants with a reduced amount of mannan show an altered seed development.

A set of mutant pea lines carrying induced mutations within the major seed-expressed starch-branching enzyme gene has been characterised at the molecular, chemical and agronomic levels. Eight of the induced mutations, three of which predicted a premature stop codon, were compared with the naturally occurring starch-branching enzyme mutation within the same genetic background.

Male sterility is an efficient trait for hybrid seed production and germplasm innovation. Until now, most studies on male sterility were on cytoplasmic and recessive genic sterility, with few on dominant genic male sterility, especially in cotton, due to lack of such mutant.

The Medicago truncatula 2HA seed line is highly embryogenic while the parental line Jemalong rarely produces embryos. The 2HA line was developed from one of the rare Jemalong regenerates and this method for obtaining a highly regenerable genotype in M. truncatula is readily reproducible suggesting an epigenetic mechanism.

Soybean is subjected to genetic manipulation by breeding, mutation, and transgenic approaches to produce value-added quality traits. Among those genetic approaches, mutagenesis through fast neutrons radiation is intriguing because it yields a variety of mutations, including single/multiple gene deletions and/or duplications.

The present investigation was conducted during the Kharif season of 2013, seeds of black gram [Vingo mungo (L.) Hepper] variety VBN 4 and ACM 07002 were exposed to gamma rays doses at 200, 250, 300 and 350 Gy and EMS (Ethyl Methane Sulphonate) doses at 20, 30 and 40 mM. Wide ranges of viable mutants were isolated in M2 and M3 generation. The mutational change in each quantitative trait can be large or small.

Coat color determines both appearance and nutrient quality of peanut. White seed coat in peanut can enhance the processing efficiency and quality of peanut oil. An integrative analysis of transcriptomes, metabolomes and histocytology was performed on wsc mutant and its wild type to investigate the regulatory mechanisms underlying color pigmentation.

The present investigation was carried out to find the efficiency and effectiveness of various mutagenic treatments of gamma rays and EMS on cape gooseberry. Genetically pure, uniform and dry seeds of cape gooseberry were subjected to 2, 5, 10, 15 and 20 kR doses of gamma rays and 0.02, 0.03, 0.04 and 0.05 M concentration of ethyl methane sulfonate along with control. Chlorophyll mutation, biological damages and viable mutant frequency was recorded in M1 and M2 generation.

Three does each of gamma rays (200, 400 and 600Gy), ethyl methane sulphonate (0.2, 0.4 and 0.6%), nitrosoguanidine (0.005, 0.010, and 0.015%), maleic hydrazide (0.01, 0.02 and 0.03%) and in combination were administered to the seeds of two greengram varieties, Sujata and OBGG-52. In M2 generation, population mean got decrease with increase in variance for all the four traits studied and the magnitude of such changes varied with mutagens, their doses and the variety. Higher the dose of treatment greater the shift in mean and variance.

An experiment was conducted to study the phenotypic characterization of mutants from different species of annual chrysanthemum by treating the seeds of different species of Chrysanthemum coronarium (Cco), Chrysanthemum segetum (Cse) and Chrysanthemum carinatum (Cca) with various doses of gamma rays (Cobalt-60) at National Botanical Research Institute, Lucknow. Immediately after the mutagenic treatment, the nurseries were raised and further transplanted in the field.
