Improving hybrid rice breeding programs via stochastic simulations: number of parents, number of hybrids, tester update, and genomic prediction of hybrid performance por Fritsche-Neto, Roberto, Ali, Jauhar, De Asis, Erik Jon, Allahgholipour, Mehrzad, Labroo, Marlee Rose

“…Therefore, our study compared various phenotypic and genomics-assisted RRS breeding schemes which used GP to predict hybrid performance rather than reducing cycle length, which allows minimal changes to phenotypic schemes. We used stochastic simulation to compare compared five RRS breeding schemes in terms of genetic gain and best hybrid performance: Traditional (TRAD_RRS), drift (DRIFT_RRS), Traditional but updating testers every cycle (TRAD_RRS_ UP), Genomic Additive (GS_A_RRS), and Genomic Additive+Dominace (GS_AD_RRS). …”

Aluminum Resistance Transcription Factor 1(ART1) contributes to natural variation in aluminum resistance indiverse genetic backgrounds of rice (O. sativa) por Arbelaez, Juan D., Maron, Lyza G., Jobe, Timothy O., Piñeros, Miguel A., Famoso, Adam N., Rebelo, Ana Rita, Singh, Namrata, Ma, Qiyue, Fei, Zhangjun, Kochian, Leon V., McCouch, Susan R.

“…Analysis of global transcriptional responses to Al stress in roots of the NILs alongside their recurrent parents demonstrated that the presence of the Alt12.1 from Al‐resistant Azucena led to greater changes in gene expression in response to Al when compared to the Alt12.1 from IR64 in both genetic backgrounds. …”

Weed management strategies to reduce herbicide use in zero-till rice-wheat cropping systems of the Indo-Gangetic Plains por Kumar, Virender, Singh, Samar, Chhokar, Rajender S., Malik, Ram K., Brainard, Daniel C., Ladha, Jagdish K.

“…In the rice–wheat (RW) systems of the Indo-Gangetic Plains of South Asia, conservation tillage practices, including zero-tillage (ZT), are being promoted to address emerging problems such as (1) shortages of labor and water, (2) declining factor productivity, (3) deterioration of soil health, and (4) climate change. Despite multiple benefits of ZT, weed control remains a major challenge to adoption, resulting in more dependence on herbicides for weed control. …”
