Earliness and yield related traits
-
At the same time, the breeding lines from the advanced generations are also used as parental lines for developing commercially exploitable heterotic hybrids. But, most often the source of early generations i.e., F3, F4, F5 and F6 segregating populations offer wider opportunities for achieving high success, because of wider genetic base.

Heterosis manifestation in tomato is in the form of the greater vigour, faster growth and development, earliness in maturity, increased productivity (Yordanov, 1983). So, by exploiting the heterosis for various yield contributing traits and earliness a speedy improvement in tomato can be done.

The present study was carried out for development of hybrids in ridge gourd for earliness and yield traits. Twenty eight crosses were developed through half diallel fashion. Evaluated the crosses and along with their parents in Randomized block design (RBD). Significant differences found in the analysis of variance for early and yield related traits which indicates enormous genetic variability present in the ridge gourd.

The present study was carried out on heterosis for fruit yield and yield related traits in sponge gourd. Fifteen hybrids of sponge gourd were developed using six parents in half diallel fashion were studied for estimation of heterosis for 10 yield contributing traits. Hybrids PSG-82 × PSG-07-04, PSG-07-04 × PSG-161 and PSG-07-04 × PSG-199 were found most promising for earliness and yield. These hybrids exhibited heterosis to the tune of 59.36, 48.45 and 43.85 per cent over their better parents and 81.58, 69.16 and 63.

Combining ability analysis was carried out for earliness, fruit yield and its related traits in okra in a 6 × 6 full diallel fashion. Both general combining ability (GCA) and specific combining ability (SCA) variances are highly significant for all the characters indicating the importance of additive and non-additive gene actions. The highest significant negative GCA effect for earliness were recorded by the parents Arka Anamika, Parbhani kranti and for fruit yield per plant the best general combiner were found to be Parbhani kranti.

Fusarium head blight (FHB) is a major disease of cereal crops, caused by the fungal pathogen Fusarium graminearum and related species. Breeding wheat for FHB resistance contributes to increase yields and grain quality and to reduce the use of fungicides.

The present study was carried out for development of hybrids in sponge gourd for earliness and yield traits. Twenty eight crosses were developed by crossing 8 × 8 diallel mating design (excluding reciprocal). Evaluated the crosses and along with their parents in randomized block design (RBD). Analysis of variance indicated highly significant differences for growth, earliness and yields characters, which suggesting presence of wide genetic variability. The magnitude of standard heterosis was found in desirable direction for early and yield traits viz.
