Research paper thumbnail of Breeding More Crops in Less Time: A Perspective on Speed Breeding

Biology

Breeding crops in a conventional way demands considerable time, space, inputs for selection, and ... more Breeding crops in a conventional way demands considerable time, space, inputs for selection, and the subsequent crossing of desirable plants. The duration of the seed-to-seed cycle is one of the crucial bottlenecks in the progress of plant research and breeding. In this context, speed breeding (SB), relying mainly on photoperiod extension, temperature control, and early seed harvest, has the potential to accelerate the rate of plant improvement. Well demonstrated in the case of long-day plants, the SB protocols are being extended to short-day plants to reduce the generation interval time. Flexibility in SB protocols allows them to align and integrate with diverse research purposes including population development, genomic selection, phenotyping, and genomic editing. In this review, we discuss the different SB methodologies and their application to hasten future plant improvement. Though SB has been extensively used in plant phenotyping and the pyramiding of multiple traits for the d...

It revealed that 55 genotypes were grouped into eleven clusters. Result envisaged that genotypes grouped within a particular cluster are more or less genetically similar. Genotypes grouped into cluster I were showed maximum intra-cluster diversity while maximum inter-cluster diversity was observed between cluster XI and V followed by cluster XI and X. So, it could be suggested that hybridization program involving genotypes from the farthest diverse clusters (Cluster XI and V and cluster XI and X) are likely to achieve wider and desirable heterotic recombinants or even transgressive segregants.

According to recent finding by WHO and FAO, around 3 billion people are at risk for zinc deficiency, 2 billion people are anaemic due to iron deficiency and about 150 million are deficient in vitamin A. These micronutrient deficiencies impose a considerable disease burden to the society through creating adverse functional outcomes include stunting growth, increased susceptibility to infectious diseases, physical impairments, cognitive losses, blindness, and premature mortality. Rice is the major staple food and source of energy for more than half of the world's population. In comparison to other cereal crop rice contain meagre amount of micro nutrient like protein (6-7%), Zn (10-33 ppm), Fe (2-34 ppm) and deficit in pro-vitamin A. Unfortunately, due to gradual genetic erosion the genetic store house of land races and traditional varieties are gradually depleted by high yielding varieties which are poor source of essential micronutrients such as Zn, Fe and pro-vitamin A in their polished (white) form. Nowadays, utilization of molecular markers associated with target allele (MAS) helps in identifying desirable segregants thereby considerably shortening the breeding cycle. Once promising high-yielding, high-nutrient lines emerge then these lines are tested in multi-location trials for confirming their stable performance for growing in mega environment.
