Genetic analysis of F2 progeny of MG20 and enf1 L. japonicus
Segregation analyses were carried out using histograms for nodule number and nitrogen fixation activity. The χ2 tests were carried out using experimental values (segregation ratio) based on nodule number and nitrogen fixation activity.
| Experimental Value | Expected Value | χ2 | P | |
|---|---|---|---|---|
| Root nodule no. | ||||
| MG20 type | 37 | 38 | ||
| enf1 type | 34 | 38 | 0.78 | 0.68 |
| MG20 × enf1 intermediate | 81 | 76 | ||
| Nitrogen fixation activity | ||||
| MG20 type | 33 | 38 | ||
| enf1 type | 35 | 38 | 1.74 | 0.42 |
| MG20 × enf1 intermediate | 84 | 76 |
