Heterosis studies for growth
-
Standard heterosis over one check (DVRT-1) was experimented with thirty hybrids of tomato. Most of these hybrids proved to have unique variation for growth and yield traits in tomato. Standard heterosis over check for total yield/plant was recorded 99.76 %.

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 investigation was carried out in two different seasons with aim to assess the heterobeltosis and standard heterosis in bottle gourd. The present study was comprised of 45 crosses developed through diallel mating design using 10 parents namely, NDBG-49-2 (P1), N. Rashmi (P2), N. Prabha (P3), N. Pooja (P4), Pusa Naveen (P5), Pb. Komal (P6), NDBG S-1 (P7), PBOG-3 (P8), NDBG-11 (P9) and Faizabadi Local (P10) at MES, Vegetable Science, NDUA&T, Kumarganj, Faizabad (U.P.) India during kharif 2015 (E1), and Rabi, 2015-16 (E2).

Screening of 45 China aster hybrids and their parents developed by crossing in diallel mating (without reciprocals) for growth, flowering, yield and quality traits. Study revealed that all the hybrids out performed with their parents indicating high amount of heterosis present in them.

Line × tester analysis was undertaken to assess the magnitude of heterosis in 32 interspecific heterotic group hybrids (G. hirsutum x G. barbadense) of cotton for seed cotton yield and its components developed by crossing eight elite hirsutum lines with four elite barbadense testers during Kharif 2010-11 at Main Agricultural Research Station, Dharwad.

The present investigation was carried out with the objective to assess the magnitude and direction of heterosis and to identify good combiners for growth, earliness and yield characters. The maximum heterosis over better parent, the best parent and the commercial check was observed in the cross Bot.G-6-2 X Arka Bahar for all the growth parameters studied except heterobeltiosis for vine length.

Thirty five F1 , s with their twelve parents in ridge gourd [Luffa acutangula (Roxb.) L.] were tested for combing ability and heterosis for growth, earliness, yield and downy mildew disease.

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.

This study was conducted to evaluate growth, physiological, yield, and cob quality traits and to estimate heterosis for yield traits of vegetable corn hybrids in spring cropping seasons in 2014 and 2015. Five inbred lines and 7 hybrids produced from these lines together with 2 checks (LVN23 and Lao 450) were laid out in RCBD experiment with 3 replications.
