It is already known that F1 tomato hybrids ussualy have increased leaf size in comparison to both parents but it was really interesting to see that in person,and,with hybrids I corssed myself:
Hybrids leaves are in the middle,pure lines used are unkown PL variety I simply labeled as "PL",a stabilized line of some unkown comercial variety I label as "J",hairless solanum pimpinellifolioum strain called "sweet pea",san marzano(SM),indigo rose(IN) and Ildi(multifloral-s).
IN-F1-J
J-F1-SM
S.Pimp.-F1-PL
And the most dramatic example,a cross of a domestic Ildi with the wild tomato solanum neorickii
Ildi-F1-S.Neorickii
It has got to be that this increased leaf area is a huge factor in explaining hybrid vigour,of course not the only factor but still these hybrids have definitely increased biomass acumulation,and totall biomass of hybrids while I can't measure precisely,is obviously way higher than parent plants,one only needs to look at the plants to conclude this,but more on that later
