Tomato is one of the main vegetables popular with customers, so it is of great importance to select and breed some pink-fruit tomato cultivars which can be stored well and have a good flavor ,to develop the selective breeding of new tomato cultivars ,improve the production of tomato with high quality ,enrich the florol-corlor cultivars of tomato and meet the needs of people.The hybrid tomato cultivar LuoYang 92-18 is F1 of the vanecular inbred line 84-2 (female parent) which was got from materials of distant hybridization through hybrids and selection of many generations and good inbred line 90-16(male parent) which was obtained by selection of many generations and introduced from abroad Combination Assay and Selection Test ,Cultivar Comparison Test ,Area Experiment and Production Test of Province ,etc.This variety is from places an upper limit on the type, lives growing trend, the ordinary blade section, Ye Seshen is green, 6-7 festival is living the first inflorescence, the inflorescence is separated 1-2 festival, 4 foreword flowers place an upper limit on, fruit Gao Yuanhuo circular, pink, luster bright, the fruit navel is small, the simple fruit weight 250 grams, not the easy dehiscent fruit, fruit degree of hardness to be high, the not abnormal fruit, commercial is good, The food taste sweet acid is moderate, the flavor is extremely good, including the sugar 2.95%, including the acid 0.45%, the saccharinic acid compared to is 6.6,VC content 404mg/kg fresh fruit, is the country examines variety Henan tomato 1 176mg/kg's 2.23 times, after the soluble solid shape content 6% (tomato breeding attack and national tomato variety subsidizes stipulation soluble solid shape content 4.5%, saccharinic acid compares 4.5), The nutrition is rich; High anti-viral disease, leaf mold, early blight; Resistance, cold resistant, bears the weak light, bears the storage and transportation; Yields per mu 6880kg generally, yields per mu above high 10000kg, suits the Spring and Autumn Period dew and the protectorate cultivation.This research also made the Cultivation Skill Regulation of good tomato LuoYang 92-18...
