Developing selection indexes & estimation of genetic parameters for traits of economic importance in dairy cattle under once-a-day milking : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Animal Science, Institute of Veterinary, Animal Biomedical Sciences, Massey University, Palmerston North, New Zealand [PDF]
, 2016 In New Zealand, about 5% of dairy herds are milked once-a-day (OAD). The cows are inseminated using sires from the twice-a-day milking system (TAD) evaluated on breeding worth (BW) or an OAD selection index.

TaPHL7 Transcription Factor Regulates Utilisation of Nitrogen and Phosphorus in Wheat
Plant Biotechnology Journal, EarlyView.ABSTRACT Macronutrients nitrogen and phosphorus are essential for plant growth and development, thus being crucial for the productivity of crops. However, the molecular mechanism regulating the utilisation of nitrogen and phosphorus remains elusive. Here, we show that the wheat (Triticum aestivum L.) transcription factor PHOSPHATE STARVATION RESPONSE ...

Heterosis and inbreeding depression for yield and its components traits in barley (Hordeum vulgare)
The Indian Journal of Agricultural Sciences, 2020 Heterosis and inbreeding depression was analysed using a set of diallel crosses involving 10 diverse parents (excluding reciprocals). Heterosis over standard parent for grain yield per plant ranged from -9.65–45.45 (%) and -14.78–12.05 (%) under normal ...

A Single‐Base Mutation in TaWAK3‐B Reduces Plant Height via Cytoskeleton in Bread Wheat
Plant Biotechnology Journal, EarlyView.ABSTRACT Introduction of Reduced height (Rht) genes into modern wheat cultivars has resulted in ‘Green Revolution’ that skyrocketed wheat grain yields worldwide since the 1960s. These ‘Green Revolution’ cultivars show shorter plant height, but higher lodging resistance and harvest index.

BMC Plant Biology, 2020 Background Heterosis is biologically important but the molecular basis of the phenomenon is poorly understood. We characterized intergeneric hybrids between B. rapa cv. Chiifu and R. sativus cv. WK10039 as an extreme example of heterosis.

Study of heterosis in Bangladeshi chilli (Capsicum annuum L.) landraces [PDF]
, 2013 Chilli is an important cash crop in Bangladesh but average yield is very low (0.89 t ha-1) and genetic potentiality of Bangladeshi chilli landraces for hybrid variety development has not been evaluated.

Plant Breeding, EarlyView.ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.
