Abstract:
The biannual field experiment was conducted during kharif 2018-19 and 2019-20 crop season at New Upland Research cum Instructional Farm, SG College of Agriculture and Research Station, Lamker, IGKV, Raipur, Chhattisgarh, India. The objective of study was to find out phenological parameters having significant role in regulation and expression of potent grain yield under rainfed agroecology. Beginning from tillering potential, Genotypes IC0477650, GEC352, IC0476864 and GEC280 was found to be good as being parallel to check varieties over the seasons. Regarding fingers per ear, two genotypes (GEC122, IC0477620) showed nine fingers; two (IR-01, GEC137) showed eight fingers; seven (IC0477650, IC0476838, GEC79, GEC400, IC0477317, GEC280 and IC0476663) displayed seven fingers. With respect to test weight, accessions IC0477406 (3.71g), GEC79 (3.61g), GEC400 (3.59g), IC0477650 (3.38g), GEC69 (3.31g), GEC122 (3.23g), GEC371 (3.18g), GEC132 (3.03g), GEC274 (3.021g) and IC0477317 (2.99g) were found overall promising for selection of grain yield. Referring to grain yield per plot, GPU67 was at first position numerically but (CD ≤ 7.396 q ha -1), it was similar to IC0476838, IC0477406 and GEC122. Similarly other checks i.e., GPU 28 and IR-01 were statistically similar with GEC371, IC0476663, GEC348, IC0477591, GEC122 and IC0477406 at same level of critical difference. Therefore, genotypes IC0476838, IC0477406, GEC122, GEC371, IC0476663, GEC348 and IC0477591 are concluded to be outcome of research and are suggested to evaluate in further varietal evaluation programme.
