tailieunhanh - Field evaluation of agronomic parameters of promised introduced tomato cultivars (Solanum lycopersicon Mill) in winter spring season 2016–2017 in Thua Thien Hue, Vietnam

The main objective of this study is to evaluate the growth ability and yield of promisedintroduced tomato cultivars during winter-spring season 2016–2017 in Thua Thien Hue province. A total of eight cultivar treatments were used, namely GC171, GC173, CLN2001A, CLN5915, CLN1621L, Hawai7996, Cherry, and ThuanDien. Three promising cultivars (CLN2001A, CLN5915, and CLN1621L) were selected from two previous experiments. | Hue University Journal of Science: Agriculture and Rural Development ISSN 2588–1191 Vol. 128, No. 3B, 2019, –40; DOI: FIELD EVALUATION OF AGRONOMIC PARAMETERS OF PROMISED-INTRODUCED TOMATO CULTIVARS (Solanum Lycopersicon Mill) IN WINTER-SPRING SEASON 2016–2017 IN THUA THIEN HUE, VIETNAM The Thi Dieu Nguyen1, Truong Thi Hong Hai 2* 1 2 Hue University, 3 Le Loi St., Hue, Vietnam Institute of Biotechnology, Hue University, Tinh Lo 10, Phu Vang, Thua Thien Hue, Hue, Vietnam Abstract: The main objective of this study is to evaluate the growth ability and yield of promisedintroduced tomato cultivars during winter-spring season 2016–2017 in Thua Thien Hue province. A total of eight cultivar treatments were used, namely GC171, GC173, CLN2001A, CLN5915, CLN1621L, Hawai7996, Cherry, and ThuanDien. Three promising cultivars (CLN2001A, CLN5915, and CLN1621L) were selected from two previous experiments. The field experiment was laid out in a randomized complete block design with three replications. Ten plants per replication were examined. The results show that CLN2001A, GC171, CLN1621L, CLN5915, and Hawai7996 have an early harvest period, ranging from 106 to 109 days, and their morphological and vegetative characteristics of are suitable under Thua Thien Hue conditions. Cultivars CLN5915, CLN1621L, and CLN2001A have a high actual yield with , , and ton/ha, respectively. The Brix degree of high fruit quality ranges from to Bx. Therefore, these introduced cultivars can be considered as promising for tomato breeding and cultivation under the local conditions.
