Analysis of statements on self-incompatibility:

• Both correct is false because Statement (II) is historically incorrect.
• Both incorrect is false because Statement (I) is correct.
• Statement (I) is correct but Statement (II) is incorrect: Statement (I) is correct because in gametophytic self-incompatibility (GSI), pollen behavior is governed directly by its own haploid S-allele genotype. Statement (II) is incorrect because Hughes and Babcock (1950) in Crepis foetida and Gerstel (1950) in Parthenium argentatum discovered SPOROPHYTIC self-incompatibility (SSI). Gametophytic incompatibility was discovered much earlier by East and Mangelsdorf (1925) in Nicotiana sanderae.
• Statement (I) is not incorrect.
  
  Option breakdown:
• Statement (II) is false.
• Statement (I) is true.
• Statement (I) is correct and Statement (II) is incorrect.
• Statement (I) is valid.

Sequential procedure of pure line selection in crop breeding:

• Year 1: Selection of superior individual plants from a genetically variable base population based on phenotype (A).
• Year 2: Progeny testing by growing individual plant-to-row progenies and rejecting undesirable progenies (D).
• Year 3: Preliminary yield trials (PYT) of selected promising progenies with checks, discarding inferior lines (B).
• Years 4-6: Multi-location replicated yield trials (MLT) across seasons/regions to test stability and performance (E).
• Final Year: Identification and release of the best pureline variety followed by breeder seed multiplication (C).

Chronological stages of micropropagation in rose:

• Stage I: Selection, surface sterilization, preparation and aseptic inoculation of axillary bud explants (A).
• Stage II: Shoot proliferation and multiple shoot induction on cytokinin medium (D).
• Stage IIb: Shoot elongation of regenerated shoots (B).
• Stage III: In-vitro root induction / rhizogenesis on auxin medium (C).
• Stage IV: Ex-vitro acclimatization and hardening of rooted plantlets (E).
