Genetic parameters of heterosis in F1 and F2 generations of chickpea (Cicer arietinum L.)

Abstract

The experimental material comprised 10 diverse lines of chickpea, viz., five exotics ICC 987 from (des; USA), ICC 1073 (desi Spain), ICC 4914 (kabuli Grece), ICC 6148 (kabuli Jordan) and ICC 5033 (desi USSR) and five Indian varieties, K 850 (desi U.P.), JG 62 (desi M.P.), N 59 (des; Maharashtra), RS 11 (desi Rajasthan) and ICC 10035 (kabuli Mutant of L 550) crossed in half-diallel fashion. The resultant F1s and F2 populations along with parents were evaluated in a randomized block design with three replications at Indian Institute of Pulses Research, Kanpur. Observations were recorded on ten randomly selected plants in each parents and F1s and on 20 plants in F2s in each replication for nine characters (Table 1). The heterotic parameters were worked out as per the methodology of Gardner and Eberhart [1] and Singh [2].
