Phenotypic diversity of panicle and nutritional traits of some widely cultivated indigenous deepwater rice (Oryza sativa L.) cultivars of Dhemaji district, Assam (India)
Deepwater rice shows some morphological and nutritional peculiarities. To evaluate the phenotypic diversity in panicle and nutritional traits, ten widely cultivated indigenous deepwater rice cultivars (viz. Panikakuwa, Kakuwa, Miabao, Dalbao, Maguribao, Negheribao, Panidhan, Bhubao, Amana and Happybao) collected from different paddy growing fields of Dhemaji district, Assam, have been taken into ...

Forty-eight years of rice improvement in Texas since the release of cultivar bluebonnet in 1944
Information on the contribution of plant breeding to changes in yields and other agronomic traits is useful for optimizing selection gains; thus, this study aimed to determine the contribution of Texas rice (Oryza sativa L.) breeding to changes in cultivars released during the 48 yr since the release of ‘Bluebonnet’ in 1944. Twenty-three cultivars were evaluated in three environments and two N ...

Mapping of quantitative trait loci using a doubled-haploid population from the cross of indica and japonica cultivars of rice
Improving the cooking and eating quality of grain has always been an important consideration in most rice (Oryza sativa L.) breeding programs. In this study, an established rice doubled-haploid (DH) population consisting of 219 lines from anther culture of the F1 of indica variety PSB Rc10 and japonica variety Nipponbare was used to identify the quantitative trait loci (QTL) for amylose content ...
