“…In the present study, significant positive heterosis in grain yield was found to be associated with number of branches per plant, pods per plant, number of clusters per plant and pods per cluster clearly indicated that heterosis for grain yield was through heterosis for individual yield components or additive or synergistic effects of the component characters. Significant positive heterotic effect for grain yield per plant over mid parent and better parent were also observed by Lakshmana et al, (2007) Sharma et al, (1998 and Vaidya et al, (2016) in ricebean.…”

Ricebean [Vigna umbellata (Thunb.) Ohwi and Ohashi] is one of the underutilized warm season annual vine legumes. Its seed contains 25% protein, 0.49% fat and 5% fibre. It is also rich in methionine and tryptophan as well as vitamins (thiamine, niacin, riboflavin and ascorbic acid) and restores soil fertility through biological nitrogen fixation (Ebert, 2014). Despite having all favourable traits, it is not much popular among the farmers due to the late maturity and indeterminate growth habit. A little improvement with respect to these traits can enhance the utility of this crop which can be done through selection of genotypes with desirable characters from the variation through recombination followed by selection. Though being self-pollinated, scope of exploitation of heterosis is limited in

“…The cross Arka Dhanwantari x IIHR Selection 2 had shown positive heterobeltiosis and 11 crosses exhibited significant negative heterosis. In a similar study Vaidya et al, (2016) reported that sixteen and three crosses manifested highly significant negative relative heterosis and heterobeltiosis in evaluation of 21 mungbean crosses. For length of inflorescence average heterosis ranges from -77.44% to 98.18%.…”

A field experiment was conducted to know the gene action and selection of superior parents of velvet bean for hybridization. The heterosis and combining ability study was carried out using 6x6 half diallel mating design excluding reciprocals. Combining ability analysis revealed that magnitude of sca variance was greater than gca variance suggesting the predominance of non additive gene action for most of the traits except days to 50 per cent flowering, number of flowers per inflorescence, number of pods per bunch and 100 seed weight where gca variance was greater than sca variance indicating predominance of additive gene action. Based on gca effects, parents Arka Dhanwantari, IIHR Selection 8 and IIHR Selection 2 were best general combiners for the traits such as number of flowers per inflorescence, pod length, pod weight, number of bunches per plant, number of pods per bunch, dry pod yield and seed yield per plant which can be used in future breeding programme. Specific combining ability studies indicated cross IIHR Selection 2 x IIHR Selection 8 as best specific combiner for the economically important traits viz., pod length, pod weight, dry pod yield per plant and seed yield per plant. The cross IIHR Selection 8 x IIHR Selection 3 was recorded high heterotic effects for dry pod yield per plant, seed yield per plant and test weight of the seed. The cross IIHR Selection 2 x IIHR Selection 8 as superior hybrid as recorded high heterobeltiosis for days to 50% flowering, pod length, pod weight, dry pod yield per plant and seed yield per plant and days to maturity which can be exploited in future breeding programme.
