Abstract/Description: | Castor (Ricinus communis L.), the premier non-edible oilseed crop,with 45-50% oil has a worldwide market due to the presence of a unique fatty acid, ricinoleic acid (80-90%). Despite its largest area (1m.ha) and highest national average productivity (1.689 t/ha) in India, several biotic stresses increase the cost of cultivation. Among them, Fusarium oxysporumf. sp. ricini (Nanda and Prasad) lead to complete wilting of plants while leafhopper (Empoasca flavescens F. Cicadellidae: Homoptera) causes hopper burn of physiologically active leaves. Resistance breeding through conventional breeding approaches is the best option to develop wilt and leafhopper resistant parental lines. Seeds of DPC-9 were treated with 55 Kr gamma rays and selection continued for presence of bloom and pistillate plants in 10 generations. In M3 generation, few plant progenies succumbed to wilt and the resistant plant progenies were continued.Among the nine advanced lines, DPC-23, a triple bloom pistillate line, recorded leafhopper resistant reaction (grade 1) compared to the susceptible check, DPC-9 (grade 4) in three locations - IIOR, Yethapur and Palem (Anonymous, 2014-15). In wilt sick plot, DPC-23 recorded 9 and 7 percent wilt incidence compared to the susceptible check, JI-35 (96%) during 2013-14 and 2014-15 respectively. Several other leafhopper and wilt resistant pistillate lines like DPC-24, DPC-25, DPC-26 and male lines like DCS-94, DCS-109, DCS-119, DCS-120 etc were developed using other conventional breeding approaches. |
