Two experiments were undertaken simultaneously (early generation evalua-tion and advanced generation evaluation respectively) during Kharif 2013-14 at S G College of Agriculture and Research Station, Jagdalpur, IGKV, Raipur, Chhattisgarh, to indentify and analyze ephemeral genotypes for their suitability in rainfed upland and present era’s climate change-laid unpredicted water stress production agro-ecosystem. In early generation testing, mean plot flowering was recorded to be 72 Days After Sowing (DAS), plant height 83cm, panicles per square meter 212 and grain yield to be 2330kg/ha. Regional check Vandana and CRR-676-1 flowered earliest by 68 DAS followed by CRR-627-35-1-5 (69 DAS) and CRR-507-11-B-1 and CRR-605-23-1. The CRR-433-2-1-1 flowered latest by 83 DAS and as per hypothesis; yield was con-siderably reduced since plant could not develop optimum source-sink bal-ance and carbon accumulation in seeds eventually. Regarding, crop yield, five genotypes placed above the local check, namely CRR-597-5-1 (29.47%), the national check i.e. Anjali (21.05%), CRR-676-1 (15.79%), CRR-433-2-1-1 (10.53%) and the regional check i.e. Vandana (7.92%). Among advanced ma-terial, interestingly, the highest yielding genotype flowered earliest (69 DAS) that suggests the accomplishment of crop growth and physio-biochemical development while utilizing the soil and environmental reserve appropriate-ly. On overall, mean yield was 2349kg/ha, whereas genotype CRR-616-B-2-54-1 ranked 1st with 2718 kg/ha yield, 69 days of flowering duration and short bold grains. The bimodal experiment concludes that ephemeral growth span and rapid veg-repo shift is critical for survival against naturally rainfed-upland and erratic drought in rice growing regions and those genotypes which maintain the physiological buffer at the shift will be able to sustain genetic yield potential.

Selection Of

Seven selection indexes based on the phenotypic value of the individual and the mean performance of its family were assessed for their application in breeding of self-pollinated plants. There is no clear superiority from one index to another although some show one or more negative aspects, such as favoring the selection of a top performing plant from an inferior family in detriment of an excellent plant from a superior family
