RESUMEN
The impact of biotechnology on mango enhancement, particularly through genetic engineering and molecular markers, has been significant. Biotechnology has revolutionized the field of agriculture, offering innovative tools and techniques for improving crop traits. In the case of mangoes, genetic engineering involves the manipulation of the organism's DNA to introduce or modify specific genes, targeting traits such as disease resistance, fruit quality, and yield. This approach has led to the development of mango varieties with enhanced resistance to pests and diseases, improved flavour and aroma, and increased productivity. Similarly, marker-assisted selection (MAS) utilizes molecular markers to identify and select plants with desired traits, bypassing the need for time-consuming and costly phenotypic evaluations. MAS has accelerated breeding programs, enabling the development of superior mango cultivars with desired traits. By exploring the impact of genetic engineering and molecular markers in mango improvement, we gain insights into their potential to address key challenges in mango cultivation and meet consumer demands.
RESUMEN
The present investigation was carried out at Horticultural Research Centre under Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut, during 2019-2020 and 2020-2021 seasons to select the promising varieties of pear. The experiment was conducted on a 7-8-year-old pear orchard spaced at a distance of 3 m × 4 m. On four varieties i.e. Baggugosa, Punjab Beauty, Punjab Gold and Punjab Nectar and each replicated thrice. Each treatment consisted of three trees with a total of 12 trees. The obtained results showed that the highest canopy spread (3.765 m), number of fruits per plant (57.995) and fruit yield per plant (6.235 kg) were found to be significant. On the other side, number of flowers per plant (98.98), number of primary branches (6.165), stem girth (31.83 cm), plant height (6.965 m), fruit weight (5 fruits) (122.45 g), fruit length (73.97 mm) and fruit width (58.505 mm) were found to be non-significant. The results of the present study indicate that on the basis of their flowering times, full bloom times and morpho-economic characteristics, Punjab Nectar appeared to be a superior variety in terms of tree morphology and others as moderate. Further, it can be concluded that the variety Punjab Beauty had more productivity and the fruits of Punjab Nectar and Punjab beauty were having more marketable fruit traits.
