Inheritance of kernel resistance to Fusarium graminearum in maize

Article Abstract:

The additive and dominance, and dominance X dominance gene effects regulate the inheritance of maize kernel resistance to ear rot caused by Fusarium graminearum. The F(sub 1) generation of a cross between resistant and susceptible maize varieties is as resistant as the resistant parent. The F(sub 2) generation and back crosses exhibit variations in their level of resistance. Additive effects explain more than 68% of the genetic variation. The results of the study indicate that the resistance is under genetic control and is affected by 4.6 to 13.7 genes.

Inheritance of a disease lesion mimic mutant in soybean

Article Abstract:

Disease lesion mimic mutants have been found in the soybean (Glycine max). These mutants have chlorotic and/or necrotic lesions despite the absence of any pathogen. A soybean mutant having this phenotype in its leaves was studied as a single M2 plant among the bulked progeny of about 150,000 plants grown from mutagenized seed of the determinate cultivar Hobbit 87. The mutant was observed to behave as a single recessive allele.

Erwin Baur or Carl Correns: who really created the theory of plastic inheritance?

Article Abstract:

Literature in the field of non-Mendelian genetics credits both Erwin Baur and Carl Correns with the development of the theory of plastic inheritance, However, further analysis shows that Baur alone developed the theory.
