Abstract

: Morphological characterization of 34 foxtail millet genotypes for 18 DUS characters revealed existence of varied polymorphism for the characters. The experimental research was conducted at AICRP on small millets, Zonal Agricultural Research Station, Shenda Park, Kolhapur (M.S.), India during Kharif 2022. It was observed that the plant growth habit erect (23) was dominant over decumbent (11); for leaf colour light green (16) was predominant over dark green (7) followed by green (11); absence of pigmentation at auricle (22) was dominant over presence (12). For leaf attitude, erect (23) was dominating over droopy (11) type; for leaf sheath pubescence and leaf blade pubescence, absence of pubescence was dominant over its presence. Medium (30) flag leaf blade length was dominant over long (3) and short (1); medium (29) flag leaf blade width was dominant over narrow (5). In inflorescence shape oblong(28) was predominant over cylindrical(6). There was observance of hundred per cent bristles on inflorescence among genotypes with length of bristles varying, long (17) was dominant over short (10) and medium (7); for peduncle length medium (29) was dominant over short (2) and long (3). Majority of the genotypes were showing apical sterility. For inflorescence compactness, medium (16) and compact (17) were predominant over lax (1). The majority of the genotypes showed presence of lobes. For ear head length, medium (18) was dominant over long (14) and short (2). In seed colour whitish (15) and yellow (17) was predominant over orange (2); for seed shape oval (25) type was predominant over elliptical (9) type of seed. As the study was based upon the given guidelines of PPV & FRA Act 2001, so each character was thoroughly observed and noted accordingly. Some characters were lightly visible, so taking observations of them was quite tedious job. All the authors contributed equally in this experimental study.

Conclusion

Out of eighteen qualitative characters studied under experiment according to DUS guidelines, presence of inflorescence bristles was unimorphic, plant growth habit, pigmentation at auricle, leaf attitude, leaf sheath and leaf blade pubescence, flag leaf blade width, inflorescence shape, inflorescence apical sterility, inflorescence presence of lobes and seed shape were dimorphic, leaf colour, flag leaf blade length, inflorescence length of bristles, peduncle length, inflorescence compactness, ear head length and seed colour were exhibited trimorphic state of expression.
