Capítulo IV: caracterización morfo-agronómica de especies y variedades botánicas del genero Lycopersicon
The seeds from 58 introductions of the genus Lycopersicon were multiplied in the glasshouse. Thirty seeding of each introductions producing germinated seed were planted for to observe the characteristics of agronomical interest. Five reciprocal crosses were made with two experimental varieties (Chonto-1091 and Napoli-1457) with the purpose of to study the crossing efficiency of the introductions. From 58 introductions planted on1y 16 produced germinated seeds (L. hirsutum- 1408, L. g1andulosum- 1403 y 1404, L. peruvianum-613 y 1409 L. pimpinellifolium- 615, L. esculentum-633 S. pennelli- 632 L. esculentum var. ceraciforme- 183, 616. 923, 1140, 1506 y 1508 L. esculentum grandifolium -1217 L. esculentum validum- 1110). The was great variability in emergence, precocity, harvest interval, fruit flower relationsphip, yield, and in the chemical and physical anaIisys of the fruits. L. peruvianum- 613 and 1409, L. glandulosum- 1403 and 1404; L. pimpinellifolium 615 did not show a severe attack of Scrobipalpula absoluta. The varieties of L. esculentum had higher crossing efficiency (84.3 %) then the species of Lycopersicon (27.7%). In Lycopersicon species the efficiencies were: L. esculentum (75%); L. pimpinellifolium (50%); L. hirsutum (40%), L. glandulosum (5%) and L. peruvianum (2.5%).
