Identification and characterization of crop mutants through molecular marker analysis are imperious to develop desirable traits in mutation breeding programs. In the present study, macromolecular variations with altered morphological, quantitative, and biochemical traits were generated through chemically induced mutagenesis via alkylating agents and heavy metals. Statistical analysis based on quantitative traits indicating enhanced mean value in mutant lines selected from the M generation as compared to previous generations.

This study involved induced mutagenesis on two Trigonella species (Trigonella foenum-graecum var. PEB and Trigonella corniculata var.

Mutation breeding is a powerful method of rapidly expanding genetic diversity, facilitating crop improvement, and ensuring food security. In a recent study, researchers evaluated the genetic variability of species using different doses of sodium azide (SA) (0.

Also, we measured PAHs in muscle tissues of Rohu (Labeo rohita), the most common edible carp fish of the Ganga River and potential human health risk was addressed. Total concentration of PAHs (∑PAHs) in water was highest at Manika Site (1470.

In this investigation, ten-day-old (fenugreek) seedlings were cultivated in a controlled environment chamber with conditions set at 70-80% relative humidity, a day/night cycle of 25/18 °C, and a photosynthetically active radiation (PAR) of 1000 μmol m s. Other groups of seedlings were subjected to temperatures of 30, 35, or 40 °C.
View Article and Find Full Text PDFL. (Fenugreek) is a valuable medicinal plant cultivated for decades for its therapeutic characteristics. Still no pronounced improvement concerning wild form was accomplished as it is a self-pollinating crop.
View Article and Find Full Text PDFBackground: DNA markers improved the productivity and accuracy of classical plant breeding by means of marker-assisted selection (MAS). The enormous number of quantitative trait loci (QTLs) mapping read for different plant species have given a plenitude of molecular marker-gene associations. In this review, we have discussed the positive aspects of molecular marker-assisted selection and its precise applications in plant breeding programmes.
