EVALUATION OF MAINTAINER AND RESTORER LINES FOR YIELD AND YIELD CONTRIBUTING TRAITS OF RICE (Oryza sativa L.)
An experiment was conducted at Bangladesh Rice Research Institute (BRRI), Gazipur during T.Aman season of 2007 with a view to evaluating seven maintainer and 30 restorer lines for yield and yield contributing characters for selecting promising maintainer and restorer lines for developing rice hybrids in our local environment. Significant variations were noticed among the parental lines for all ...
متن کاملMorpho-physiological Response of Rice (oryza Sativa L.) Varieties to Salinity Stress
Morpho-physiological response of 7 rice (Oryza sativa L.) varieties viz., Moroberekan, Co39, Azucena, Bala, IR64, Kalinga-III and Nipponbare was assessed under control and 100 mol m NaCl + 5 mol m CaCl2 stress in a flood bench system in greenhouse. Physiological and growth parameters were recorded after 21 or 42 days of salt stress. The statistical analysis revealed significant differences amon...
متن کاملCorrelation Studies in Rice (Oryza sativa L.)
Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
متن کاملDevelopment of a platform for breeding by design of CMS restorer lines based on an SSSL library in rice (Oryza sativa L.)
Exploitation of the heterosis of hybrid rice has shown great success in the improvement of rice yields. However, few genotypes exhibit strong restoration ability as effective restorers of cytoplasmic male sterility (CMS) in the development of hybrid rice. In this study, we developed a platform for the breeding by design of CMS restorer lines based on a library of chromosomal single segment subs...
متن کاملGenetics of hybrid sterility and hybrid breakdown in an intersubspecific rice (Oryza sativa L.) population.
F1 hybrid sterility and "hybrid breakdown" of F2 and later generations in rice (Oryza sativa L.) are common and genetically complicated. We used a restriction fragment length polymorphism linkage map and F4 progeny testing to investigate hybrid sterility and hybrid breakdown in a cross between "widely compatible" O. sativa ssp. japonica cultivar Lemont from the Southern U.S. and ssp. indica cul...
