Poor grain plumpness (GP) is one of the main constraints to reaching the yield potential of hybrid rice. In this study, the GP of 177 rice varieties was investigated in three locations across 2 years. By combining the genotype data of 261 simple sequence repeat (SSR) markers, association mapping was conducted to identify the marker-GP association loci.

A field experiment was conducted during kharif season of 2019 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) to evaluate rice (Oryza sativa L.) hybrids under agro-climatic conditions of U.P. The experiment was carried out to find the performance of 10 hybrids, which laid out in Randomized Block Design (RBD) & replicated thrice.

An investigation was taken up to study the magnitude of heterosis for nine characters in rice viz., days to 50 percent flowering, days to maturity, plant height at maturity, productive tillers per plant, tillers per square meter, thousand grain weight, grains per panicle, and yield per plant. The base material for this experiment consisted of 36 F1s involving three cytoplasmic male sterile lines (CMS) and twelve diverse restorers in line x tester mating design along with best varietal check Phule Samruddhi and best hybrid check Sahyadri-4.

Rice leaves consist of three distinct regions along a proximal-distal axis, namely the leaf blade, sheath, and blade-sheath boundary region. Each region has a unique morphology and function, but the genetic programs underlying the development of each region are poorly understood.

Pollen formation and development is important for crop fertility and is a key factor for hybrid development. Previous reports have indicated that Arabidopsis thaliana TAPETUM DETERMINANT1 (AtTPD1) and its rice (Oryza sativa) homolog, OsTPD1-like (OsTDL1A), are required for cell specialization and greatly affect pollen formation and development.

A field experiment was conducted during Kharif season of 2018 in Alfisols to study grain yield of hybrid rice varieties as influenced integrated nutrient management. Results revealed that V1 (IRH-103) found significantly highest N, P and K contain in grain and straw of than V2 (IRH-111) and in different nutrient management N5 (150% RDF through inorganic) was observed significantly higher N, P and K contain in grain and straw.

In the present research work six CMS lines viz., JMS 11A, JMS 21A, CMS 11A, CMS 23A, CMS 52A and JMS 18A were mated with seven testers viz., JGL 32979, JGL 32994, JGL 33060, JGL 33080, JGL 33366, JGL 34561 and JGL 34564 in Line X Tester mating design resulting in 42 hybrids. The parents and their 42 hybrids along with four checks (US 312, 27P63, NLR 34449 and TN 1) were evaluated by planting in Randomized Block Design with two replications at Regional Agricultural Research Station, Polasa, Jagtial.

Field experiment was conducted at Agronomy and ACRIP Research Block, Department of Agronomy, Agricultural College and Research Institute, (Tamil Nadu Agricultural University, Coimbatore) Madurai during kharif season, 2007, to study the influence of rice variety, hybrid, irrigation regimes under raised bed and drip fertigation. The study revealed that growth and yield contributing characters were higher in CO(R)H 3 with raised bed (RB) 120cm bed width (BW) – Maintaining water in furrow and recorded highest grain yield of 6.452 t ha-1 .

The major yield advantages are related to proper crop establishment, efficient utilization of the natural resources and better weeds suppression due to proper plant population and together with other agronomic cultural practices. But in Jharkhand situation, information on optimum seed rate of suitable hybrid rice for aerobic is very meager.
