“…The hybrids Rm-9-133 x Rm-9-126 (6.62 per cent) showed the highest heterosis over better parent and also recorded the highest standard heterosis of 9.72 per cent and 10.43 per cent over the checks Co-4 and GBM-1 respectively. Similar findings were also reported in greengram by Reddy (1998), Joseph and Santoshkumar (2000), Sawale et al (2003), Anbumalarmathi et al (2004), Kumar et al (2007), Barad et al (2008), Dhuppe et al (2010) and Reddy et al (2011).…”

Twenty one crosses resulting from 7 x 7 diallel excluding reciprocal were studied to know the magnitude of heterosis over better parent and standard variety for yield and its attributing characters in rabi mungbean. The highest heterosis to the extent of 37.23% over the check Co-4 and 82.20 % over the check GBM-1 was observed in cross combination Co-4 x Meha for seed yield per plant, which also exhibited high heterosis percentage for yield and yield components. The promising hybrids viz. Co-4 x Meha, Co-4 x GBM-1, GBM-1 x Meha and Rm-9-129 x Co-4 were identified which have great potential to exploit the hybrid vigour or to isolate the desirable segregants for the development of rabi mungbean varieties with chilling tolerant ability or photo-thermo insensitivity, so as to exploit potential of rabi mungbean in heavy rainfall zone as rice fallows.

In order to study the combining ability, genetic parameters and gene actions of yield, yield components and quality characters in rice, fifteen F2 generation of a 6×6 diallel cross, excluding reciprocals, was grown in a randomized complete block design (RCBD) with three replications. The results of analysis of variance showed significant differences between the genotypes for grain yield (GY), 100-grain weight (HGW), number of panicles per plant (PN), panicle length (PL), number of full grains per panicle (FGN) and for quality characters including amylose content (AC) and gel consistency (GC). The results of combining ability analysis revealed that general combining ability (GCA) and specific combining ability (SCA) were significant for characters GY, FGN, GC, AC, HGW and PN indicating the involvement of additive and non-additive effects in their inheritance, however high amounts of Bakers ratio remarked that additive gene effect had more portion in controlling these traits. The best combiners for GY, HGW, FGN, PN and PL, were RI18447-2, IR 50, Daylamani, RI18430-46 and Daylamani respectively. For AC and GC, the best combiner was Daylamani. Hayman's graphs showed that regression line passed below the origin cutting Wr axis in the negative region for HGW, PN, PL and GC, indicating the presence of over dominance. Estimates of genetic parameters showed significant

“…These findings are in close agreement with the various workers who reported a standard heterosis of more than 20 per cent for grain yield increase over standard variety.
