 ABSTRACT

Pulses in India have long been considered as only source of poor man’s protein. India is the largest importer, producer and consumer of pulses (Jitendra et al., 2011). India accounts for 33% of the world area and 22% of the world production of pulses (Amarender, 2009). Pulses production in India 18.34 million tonne (ICAR 2013-14).  Heterosis in F2 would provide information on residual heterosis with respect to yield, general vigour, quality etc., which may provide scope for selection of desirable hybrids for further progressive generation for selection of elite lines one needs to elucidate the nature of gene action controlling economic characters. Relative heterosis as well as heterobeltiosis in high magnitude was observed in F2 population in cross PS-16 x TM-99-50 of for 50% maturity, days to 50% flowering and number of pods plant-1. Among the F2 population significant and maximum average heterosis and heterobeltiosis was observed in HUM-12 x Basanti for number of pods plant-1. Relative heterosis as well as heterobeltiosis were observed in high magnitude for HUM-12 x Bireswar for protein content. Highest significant average heterosis and heterobeltiosis over mid parent was observed for pod length in HUM-12 x PS-16.

Key words: Heterosis, Yield, Hybrid, Germplasm
