In order to investigate the effect of the "afila" genotype on the plant height, the peas variety Filigreen, of the "afila" type, was crossed with 12 other varieties possessing normal leaf structure. At its recessive homozygous stage, the "af gene causes the modification of the pea plants so that they only form vines with stipules instead of normal structure leaves. The genetic analysis of F1, and F2 generation (the segregation ratio between the normal and "afila) leaves being 3: 1) proved the monogenic recessive character of this feature. Concerning plant height, F, hybrids were on average 12% higher than their male parents. In the F2 generation, "AF AF" plants were 6% lower compared to F, generation plants, while "af af plants were 11% lower. The "AF AF" genotype plants were 5% higher than their male parents, but the "af af genotype plants had the same height as their male parents.
