Research paper thumbnail of Stability Assessment for Improved Mustard Production in Ecologically Diverse Regions of Jharkhand: Insights from AMMI and GGE

Signi cant differences among the genotypes are observed, with environmental factors and their interactions exerting a considerable in uence. Utilizing the AMMI and GGE biplot methods, the study delves into the intricate interactions affecting economically vital traits such as seed yield per plant and oil percentage. The combined effect of environment and interaction explains a substantial portion of the observed variation of 79.6 and 58.9% on seed yield per plant and oil % respectively. The rst two principal components together explained larger portion of 85.2% and 89.5% of the GXE variation of seed yield per plant and oil % respectively. The AMMI analysis had identi ed that, the genotypes Kranthi, PA-5232 and BAUM-09-12-1 for seed yield per plant and BAUM-08-18, Shivani, DRMRCI-70 and Pusa Bold for oil % are stable performers. The GGE biplot analysis and AMMI have commonly identi ed BAUM-09-12-1 and Pusa Bold as high yielding and most stable for seed yield per plant and oil % respectively. The results of AMMI identi ed ranchi as most ideal environment for selection of genotypes for both seed yield per plant and oil%, but GGE differs in-terms with Ranchi as ideal only for oil% and dumka for seed yield per plant. The availability of the above information of genetic variability and stability of genotypes for seed yield per plant and oil % can aid improving mustard production levels and self-su ciency in edible oils.

It was disclosed from the results of the analysis of variance that there exists a difference among the 23 genotypes for all the 18 traits under consideration. The trait including primary branches per plant, secondary branches per plant, plant height, swelling capacity, swelling index, biological yield per plant, and seed yield recorded high amounts of GCV and PCV. High heritability combined with high genetic advance was documented for the trait’s plant height and seeds per plant, whereas high heritability coupled with low genetic advance, was recorded for the t...

Cereals are the predominant food grains consumed by the majority of the population across the globe, with rice alone feeding 50% of the global populace. In order to feed the geometrically rising population, there is a need for a dramatic upsurge in rice production levels. But climate change is one of the causes resulting in the rising of various biotic and abiotic stresses. The advancement of science had resulted in the development of Genome editing technologies like clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9), transcription activator-like effectors nucleases (TALENs), and zinc-finger nucleases (ZFNs). Among these techniques, due to ease of application, and high precision crisper-cas technology had emerged as a solution to overcome various obstacles in the journey of enhancing production levels of rice. In this, we will review various improvements made in the rice crop using crispercas which ultimately led to enhanced production.
