Shallow swamps can be used for rice production during the dry season. The problem that occurs is lack of water. technology needed to overcome these problems drought tolerant superior varieties. purpose this study obtain varieties on shallow lebak swampy. was conducted from April 2019 August 2019. were Situ bagendit, Rindang 1, 2, and Siam (local) as comparison. Data collected included: plant he...

Total spikelet number per panicle (TSN) is one of the most important traits associated with rice yield potential. This trait was assessed in a set of 334 chromosomal segment introgression lines (ILs: BC(3)-derived lines), developed from new plant type (NPT) varieties as donor parents and having the genetic background of an indica-type rice variety IR64. Among the 334 ILs, five lines which had d...

Field experiments/On Farm trial (OFT) were conducted at Farmers field of village, Halsi, Lakhisarai under the supervision ICAR-Krishi Vigyan Kendra, BAU, Bihar, India in 2012-13 and 2013-14.To established a uniform plant stand for maximum yield net return ultimately drudgery reduction. The experimental was laid out Randomized block design replicated four times (Number Farmers) with six treatmen...

The genetic basis underlying the relationship between the source leaves (the top two leaves) and the sink capacity in rice was investigated in a replicated trial of 2418 F2 derived F4 progeny from an inter-subspecific cross between cv. Lemont (japonica) and cv. Teqing (indica) and a complete linkage map with 115 well distributed RFLP markers. Path analysis indicated that 50% of the phenotypic v...

Uniformity of stem height in rice directly affects crop yield potential and appearance, and has become a vital index for rice improvement. In the present study, a doubled haploid (DH) population, derived from a cross between japonica rice Chunjiang 06 and indica rice TN1 was used to analyze the quantitative trait locus (QTL) for three related traits of panicle-layer-uniformity; that is, the tal...

The present experiment was carried out in twelve genotypes including IRRI introgression lines and a Japonica cultivar to analyse the genetic variability, heritability, gain. Significant differences were observed among genotypes. All traits under study recorded high phenotypic coefficient of variation (PCV) than genotypic (GCV) indicating presence environment controlling traits. But, less differ...

Rice bran application just after transplanting has been increasingly practiced as a herbicide-substitute for organic rice production in Korea. However, this practice is frequently reported to be unsatisfactory in weed suppression. An experiment with five treatments that combine flooding depth (shallow and deep), rice bran application level (low and high), and herbicide application was carried o...

Twenty hybrids were produced using five CMS lines viz., BRRI3A, BRRI9A, IR73328A, BRRI10A and IR78355A and four restorers viz., BRRI12R, BRRI13R, BRRI14R and BRRI15R following line x tester mating design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids at BRRI, Gazipur, Bangladesh from July 2008 to May 2009. Data were recorded from...

Twenty-eight lines including 18 F1 plants, 9 parents, and one commercial were studied for estimation of genetic variability, heritability, advance at Agricultural Research Station, Kunaram. Analysis variance revealed highly significant differences among the genotypes all traits indicating presence a considerable amount variability yield its components, quality gall midge incidence. PCV values n...
