“…These insects feed mainly on stems, and account for 28% of total plant dry matter reduction ( Sōgawa, 1994 ). Feeding by low-density BPH populations can reduce rice yields ( Watanabe et al , 1997 ), while heavy infestation causes ‘hopperburn’ ( Sōgawa, 1982 ). The BPH is also a vector of viruses responsible for ragged stunt and grassy stunt diseases.…”

“…BPH, Nilaparvata lugens (Homoptera: Delphacidae) induces direct damage to the plant by sucking the sap from phloem, causing hopper burn and transmitting important viral diseases such as ragged and grassy stunt viruses. Even if the planthopper population is not significant enough to kill the plants, BPH feeding may still lead to considerable yield losses (Watanabe et al 1997). More than 28% of the total dry matter of rice plants can be consumed by BPH, if infested during reproductive phase of rice crop (Sogawa et al 1994).…”

Brown planthopper (BPH) is one of the destructive insect pests causing significant yield losses in rice. BPH causes direct damage to the rice plants by sucking the sap from phloem, causing hopper burn and transmitting viral diseases like grassy and ragged stunt viruses. Several resistant donors have been identified from time to time, but the new biotypes of the pest arise to defeat the extended use of resistance genes in a single variety. This necessitates the regular identification of new resistant donors along with their nature of inheritance and gene action controlling the resistance. Knowing the inheritance pattern, gene action and number of genes controlling a trait helps the plant breeders to plan the effective breeding approaches for crop improvement. The present investigation was hence carried out to know the inheritance pattern, gene action and number of genes controlling BPH resistance in newly identified sources. The results indicated that the BPH resistance in PHS 29 genotype is under the control of single recessive gene. Whereas, it is controlled by two recessive genes in MRST 3 genotype. This reveals that relatively higher population size will be required to recover desirable segregants in the segregating populations involving MRST 3 genotype as one of the parents as compared to that involving PHS 29 genotype as parent. Since, the resistance in both the cases being recessive in nature, the trait will hence show significant additive effect, indicating that pure line development will be desirable for improvement of such a trait.
