ADVANCED GENETIC STRATEGIES FOR IMPROVING RICE YIELD

Abstract

Every crop breeding effort aims to increase production. Despite several advances, most worldwide breeding projects have traditionally focused on improving grain production potential, insect/pest and disease resistance, grain quality, and stress tolerance. Almost all rice breeding initiatives aim to increase grain yield. However, the value of this crop varies by area, country, and even within a country. Finding innovative ways to increase the genetic grain production potential of all kinds has significant ramifications. Rice breeders have improved crop yields significantly. The green revolution gave us semi-dwarf rice types, a new rice plant type, and hybrid rice. Conventional hybridization, ideotype and heterosis breeding, broad hybridization, genetic engineering, molecular marker-assisted breeding, and CRISPR-Cas9 are all possibilities for increasing yield potential. Pedigree is the most common breeding technique for enhancing rice, but hybrids and population improvement are also used. Many groups are still working to integrate biotechnology tools into breeding programs and balance budget allocation between conventional and innovative approaches. Modern technology, such as biotechnology, has recently increased agricultural productivity by improving crop yields and reviewing several genome editing methods to enhance rice production.
