“…Surprisingly, better agronomic and botanic properties characterize the majority (48 percent) of the mutant varieties recorded in the Mutant Variety Database. This could be owing to the fact that botanic and agronomic features are easily observable, and for the most part, screening does not require specialized equipment [34]. Mutagenesis in TILLING is linked to the extraction of chromosomal DNA from each mutant and the use of sophisticated molecular tools to the population's molecular level screening.…”

A mutation is an abrupt, heritable alteration in a living cell's DNA that is not brought about by genetic recombination or segregation. The deliberate use of mutations in plant breeding is known as "mutation breeding." Mutation breeding provides the advantage of improving a fault in an otherwise excellent cultivar without sacrificing its agronomic and qualitative features, in contrast to hybridization and selection. There is no simpler solution than mutation breeding to enhance seedless crops. These benefits have led to the development of a market for mutation breeding in plant breeding since the initial release of mutant cultivars derived from fundamental mutation research in Europe. Both physical and chemical mutagens have improved methods for inducing mutations in major crops, and strategies for selecting mutant populations have been detailed. A broad range of mutations that have not been previously documented have been detected, and new mutagenic factors like cosmic rays and ion beam radiation are being studied. However, ionising radiation and alkylating chemicals continue to be widely used. The efficiency of mutant breeding has increased as a result of the advent of reliable in vitro methods for numerous crop species. In vitro methods are particularly effective because they can manage sizable mutagenized populations in a small area, have a quicker progeny turnover rate in vegetatively propagated species, and can screen for a variety of biotic and abiotic stress factors in the culture environment. Over the last ten years, there have been significant advancements in mutant screening, with reverse genetic methods now being prioritised. Thus, the combination of molecular methods and mutation techniques is opening up new and intriguing possibilities for contemporary plant breeding.

Mutations occur as a result of alterations in DNA or during the replication/cell division process. For agricultural development, plant breeding necessitates genetic variety of valuable features. Multiple mutant alleles, on the other hand, constitute a source of genetic variety for crop breeding and, in many cases, functional investigation of the targeted gene. Plant breeding can only improve when the breeder has access to enough variation for a particular trait. Any change in an organism's DNA that is not caused by normal recombination and segregation is referred to as a mutation. Exposure to mutagenic agents such as radiation or certain chemicals, as well as faults made during normal cell division and replication, are all possible causes. The first breeding successes were achieved by utilizing spontaneous (naturally occurring) mutations. The most well-known example is the use of semi-dwarf wheat and rice mutants during the 'Green Revolution.' Induced mutagenesis is becoming increasingly popular in plant molecular biology as a method for identifying and isolating genes, as well as studying their structure and function. Molecular mutation breeding is ushering in a new era of crop enhancement mutation breeding. In the coming years and decades, mutation breeding will play a vital role in crop improvement and resolving concerns related to global food security. As a result, the goal of this review paper is to evaluate the function of mutant breeding in crop development and how it might be used.

“…The gene er‐1 is recessive and can provide immunity and durable PM resistance (Sun et al., 2016a; Tiwari, Penner, & Warkentin, 1997). The expression of resistance gene er‐2 is strongly influenced by temperature and leaf age, its application in pea breeding is limited (Sun, He, Dai, Duan, & Zhu, 2016b; Zong et al., 2019). Er‐3 is mainly expressed as a post‐penetration hypersensitive response (HR) that stops the colony growth, but has not been exploited in breeding (Warkentin et al., 2015; Fondevilla, Cubero, & Rubiales, 2011).…”

Inheritance of resistance of two pea lines to powdery mildew

2020

View full text Add to dashboard Cite

The GRICAND, Andean Crops Research Group has identified two resistant pea (Pisum sativum L.) lines to powdery mildew (PM) (Erysiphe pisi): ILS6527 (resistance of foliage and pods) and UN6651 (pods only resistance). This study established the inheritance of these two distinct PM‐resistance genotypes. Resistant lines ILS6527 and UN6651 were crossed with two susceptible varieties (Andina and San Isidro) and their respective generations (F1, F2, BCr, and BCs) were evaluated for PM resistance in naturally infected field tests. Data were subjected to chi‐square (χ2) and homogeneity test. The two crosses of ILS6527 segregated in a monogenic Mendelian ratio of 3 susceptible: 1 resistant in F2 generation, and 1 susceptible: 1 resistant ratio in BCr, which indicate a recessive control of resistance. The resistance gene in ILS6527 may be allelic with er‐1. UN6651 exhibited PM resistance only in pods, the F2 and backcrosses from the crosses with UN6651 segregated in a manner indicative of recessive resistance.
