Vedclass · Answer

(D) The conventional method of breeding for disease resistance involves several steps:$1$. Screening germplasm for resistance sources: This involves identifying plants that possess the desired resistance genes ($iii$ is correct).$2$. Hybridization of selected parents: The resistant plants are crossed with high-yielding or other desirable varieties ($ii$ is correct).$3$. Selection and evaluation of the hybrids: The progeny are tested for resistance and other traits.$4$. Testing and release of new varieties: The selected lines are evaluated in multi-location trials for yield and other agronomic traits before being released to the market ($iv$ is incorrect).$5$. Productivity is generally expected to increase or be maintained while adding resistance,so stating there is 'no change' is not a defining characteristic of the breeding method ($i$ is incorrect).Therefore,statements $(ii)$ and $(iii)$ are correct.
