MODIFIED TRIPLE TEST CROSS ANALYSIS FOR YIELD AND YIELD COMPONENTS IN OKRA (ABELMOSCHUS ESCULENTUS (l) MOENCH)

Abstract

Information on gene action for yield and its related traits in different populations is pre-requisite for plam1ing effective breeding programme. Several biometrical procedures are available for obtaining information on the nature of genetic variation, but the triple test Cross (TTC) [2] and its modification [1] is the most efficient for detection and estimation of epistatic variation. The present investigation consists of two testers (Arka Anamika and Pusa Sawani) alongwith 20 parental lines (p), 20 L1i and 20L2i families which were grown in a randomized block design, replicated thrice during the summer and rainy seasons of 1994 keeping inter-row and intra-row spacing of 45 and 30 em. respectively. Observations were recorded on 5 random plants from each family in each replication on ten quantitative characters.
