In-vitro Hybridization of Tomato (Solanum lycopersicum L.)

Abstract

Tomato (Solanum lycopersicum L.) hybrid variety trials were conducted at “Directorate of vegetable seed production farm Quetta” where two varieties of tomato (Riogrande & Dolor) were evaluated on the basis of days to flowering, fruit setting, length and width of fruit, average fruit weight, plant height , yield, maturity period and producing new hybrid variety which is suitable for climate prevailing in Quetta. The development strategy was “Inter-varietal Hybridization” and hybrid progeny often have a higher yield, increased resistance to disease, and an enhanced performance in different environment compared with the parental lines. Cost effective mechanism to create commercial hybrid seed parental line is one of the vital components which ultimately examine the commercial viability of hybrid varieties. Emasculation was aimed at first generation (F1) hybrid seed utilization globally in term of salient cultivars and volume of utilized seed. (F1) hybrid seed can be characterized into manual pollinated and gene control pollinated species. After careful research study of tomato hybrid seed production in Quetta was illustrated different production steps from selection of site to actual growing of the male and female parents, emasculation of the male flowers pollination, eventually we got a suitable tomato hybrid for the Quetta and other similar climatic regimes.
