NEW PRIORITIES IN PEA BREEDING
2023
Zadorin, A. M. | Kononova, M. E.
A new form of pea with tendril-leaflet leaves has been created at the Federal Scientific Center of Legumes and Groat Crops. Pronounced, depending on the light regime, stratified heterophyllia, gave reason to name the new form chameleon. The special structure of the leaf apparatus of pea plants of the tendril-leaflet form allows combining a high potential for lodging resistance and productivity. During the study of the heterophyll form of pea, varietal specificity with respect to leaf plate formation on tendril-leaflet leaf, as well as morphological differences between tendril leaves of tendril and tendril-leaflet forms were noted. Currently, the State Register breeding achievements of the Russian Federation includes 2 varieties of peas created on the basis of the tendril-leaflet form of the chameleon – Spartak and Jaguar, approved for cultivation in seven and five regions, respectively. The varieties are characterized by high productivity, over 6 t/ha and, thanks to leafless and tendril-leaflet leaves in combination with a strong stem, increased resistance to lodging
