Method for breeding seeds of hybridized tomato

Abstract

The invention relates to a method for breeding the tomato hybrid with good-quality, transportation-resistance and being suitable for long-season cultivating, belonging to the field of using the goodness of crop hybrid, which comprises choosing parental generation, conserving and breeding the parental generation and producing the first hybrid. The invention is characterized in that it applies two homozygous and stable autocopulation '98-2108-1-1-1' and '96-21-2-1-1-1' as male parent and female parent individually, crossing artificially and producing the '152' hybrid. The strain possesses the following characteristics: good quality, high yield and output value, strong disease-resistance, high growth potential, dark green leaf and with the content of soluble solid being 5.0%, the proportion between sugar and acid being 6.8, the content of Vc 15.91mg / 100gFW. The average product per mu is 11241.6kg, which is 19.8% more than '2', and the field evaluation of the strain is high-impact ToMV, medium-impact CMV, immune to wilt and resistant against leaf mold.<0}

Problems solved by technology

However, most domestic varieties have poor sustainable growth and fruit setting ability, and there is a big gap between foreign excellent varieties in terms of fruit appearance, commodity quality and fruit storage and transportation resistance.

Every year, the country spends a lot of foreign exchange to import foreign seeds, and the imported varieties from the Netherlands, Israel and other countries are expensive, and the parents are kept strictly confidential and cannot be used directly. Variety is an important problem to be solved urgently in tomato breeding and production
