Line X Tester Analysis Across Environments in Tomato
Author: Puja Rattan
Publisher: LAP Lambert Academic Publishing
ISBN: 9783838336824
Category : Tomatoes
Languages : en
Pages : 228
Book Description
Study was carried out at Palampur and Bajaura in India.7 lines, 4 testers & their 28 hybrids were evaluated in RBD with 3 replications in line x tester mating design. ANOVA revealed significant differences among genotypes and GxE interactions, the line x tester analysis revealed significant differences due to line x location, tester x location & line x tester x location interactions (tested against error mean squares) at both locations and pooled analysis for most of the traits. GCA effects revealed that the lines BT-18 and Rodade and tester Hawaii-7998 and EC-392698 at Palampur;lines BL-333 and CLN-2123 and testers EC- 191536 and EC-392698 at Bajaura were good general combiners for yield and its contributing traits. However, BT-18 and BL-333 among lines and EC-392698 and Hawaii-7998 among testers were good general combiners for maximum traits studied in over all pooled analysis. Based on combing ability, heterosis and mean performance, crosses BT- 18xHawaii-7998, RodadexEC-392698 and BL-333xEC- 191536 in overall pooled analysis had great promise for further exploration. Preponderance of non additive gene action was fond in most of the traits.

Breeding of Tomato Genotypes For Yield And Disease Resistance

Pages : 240
Book Description
Tomato [(Solanum lycopersicum Mill.) Wetted] is one of the most important vegetable crops grown in India. However, modern cultivars of tomato have a limited genetic diversity further the demand for high yielding disease resistant hybrids is alarming. In this study an effort was made to increase genetic variability for development of ToLCV resistant high yielding varieties and hybrids by utilizing exotic tomato breeding lines. Diversity analysis of 19 exotic tomato breeding lines and popular varieties viz., Pusa Ruby (P20), Vaibhav (P21) and Arka-Vikas (P22) was made with the D2 analysis, PCA, RAPD and SRAP markers, which revealed that exotic lines are diverse from popular varieties. Nineteen exotic tomato breeding lines and cultivars viz., P20, P21 and P22 were crossed in line x tester design to assess the combining ability and heterosis. A perusal of the results indicated that P21 x PT4227A, P22 x CLN2123E, P21 x CLN2768A, P21 x CLN2777F, P21 x CLN2400B, P22 x CLN2460E, P22 x CLN2777B, P20 x CLN2498E and P20 x CLN2777F showed significant heterosis over the best check hybrid. Further these hybrids could be used to develop mapping population and breeding for hybrid development.
