Hand pollination

Twenty seven pigeonpea [Cajanus cajan (L.) Millsp.] hybrids were developed by hand pollination using three CMS lines (A lines) and nine testers (R lines). These hybrids along with their parents and two standard checks (VL Arhar1 and ICPL 161) were evaluated in a randomized block design with three replications during kharif 2016-17 for the heterosis studies.

The maximum number of fruits set was recorded in open-pollination + hand-pollination treatment (80.42% and 77.14%) and open-pollination (78.85% and 75.00%), followed by hand-pollination (65.42% and 61.42%) in C-1076 and C-1106 cultivar respectively. Without insect pollination treatment resulted in zero per cent fruit set in both the pumpkin cultivars (C-1076 and C-1106).

Interspecific hybridization in okra is of immense value to exploit the diversity of species in the genus Abelmsochus for developing male sterile lines and/or advance breeding lines possessing resistance to YVMV and ELCV diseases. The present investigation was carried out during the year 2015-16 to study the pattern of interspecific hybridization in genus Ablemoschus involving ten wild species viz., A. angulosus var. angulosus, A. angulosus var. grandiflorus, A. caillei, A. ficulneus, A. manihot ssp. tetraphyllus, A. moschatus, A. tetraphyllus var. pungense, A. tetraphyllus var.

The present study was designed to transfer mungbean yellow mosaic virus (MYMV) resistance in urdbean from ricebean. Four MYMV-resistant ricebean genotypes (RBL1, RBL6, RBL35, and RBL50) were hybridized as males with the MYMV-susceptible urdbean line PS 1 using hand emasculation and pollination techniques under field conditions.
