Improved rice varieties are central to productivity growth, risk management and grain-quality differentiation, yet their commercial success depends on more than genetic performance. In South India, and particularly in Telangana, the paddy-seed market combines public breeding, public and private multiplication, formal certification, truthfully labelled seed, dealer networks, co-operative channels and farmer-saved seed. This institutional complexity makes both "market share" and "buying behaviour" difficult to measure consistently. This critical narrative review integrates evidence on seed-market structure, varietal diffusion, purchase channels, trait preferences, information, price and risk, and downstream grain-market signals, with special attention to Telangana. Literature published from the liberalisation-era transformation of India's seed sector through 8 June 2026 was identified through accessible scholarly indexes, repositories, journal and DOI records, citation searching and relevant government sources. The evidence indicates that published market-share estimates are often not directly comparable because studies alternately use cultivated-area share, seed-source share, certified-seed output, inferred varietal diffusion, sales volume or revenue. Farmer choice is correspondingly multidimensional: yield and expected profit matter, but so do seed purity and germination, varietal duration, pest and disease tolerance, lodging resistance, irrigation requirements, grain and milling quality, seed price, subsidy, timely availability, advice, prior experience and seller credibility. Telangana illustrates a particularly strong public-private interface, but available farmer studies are local and cross-sectional and do not support precise state-wide firm- or brand-level market shares. Evidence from Telangana Sona further shows that agronomic attributes can be undermined by weak miller demand or unfavourable procurement prices. The principal knowledge gap is therefore not simply a shortage of adoption studies, but the absence of integrated longitudinal data linking verified varietal identity, retail seed transactions, cultivated area, farmer preferences and output-market outcomes. A defensible market-intelligence architecture would combine representative farm panels, retailer and seed-company sales records, genetic or documentary varietal verification, and miller/procurement data.
