Harvesting high quality lint, a long-awaited breeding goal-accomplished partly, can be achieved by identifying DNA markers which could be used for diagnosing cotton plants containing the desired traits. In the present studies, a total of 185 cotton genotypes exhibiting diversity for lint traits were selected from a set of 546 genotypes evaluated for fiber traits in 2009. These genotypes were ex...

In this paper we give an example which shows that the convolution theorem (Boll, [1], Hajek, [2]) cannot be extended to infinite-dimensional shift experiments. This answers a question posed by van der Vaart, [8], and which has been considered also by LeCam, [4].

The application of harvest aids is an important prerequisite for the mechanical harvesting cotton that can effectively reduce impurity content and improve picking rate operating efficiency machine-picked cotton. However, determining appropriate spraying time to achieve synergistic improvement boll weight fiber quality still unclear. In this study, damage as well its quantitative relationship ag...

A field experiment was conducted at College farm, of Agriculture, PJTSAU, Hyderabad during kharif, 2021-22 to study the growth and yield Bt cotton as influenced by varied plant densities nitrogen doses under high density planting system. The results revealed that among densities, height (102.8 cm) drymatter production (7396 kg ha-1) were higher with spacing 90 x 15 cm (74,074 plants on par 20 (...

Early detection of within-field yield variability for high-value commodity crops, such as cotton (Gossypium spp.), offers growers potential to improve decision-making, optimize yields, and increase profits. Over recent years, publicly available datasets have become increasingly at a resolution where prediction is possible. However, the viability using these with machine learning predict lint ke...

The extreme climate of the Canadian Prairies poses a major challenge to improve yield. Although it is possible to breed for yield per se, focusing on yield-related traits could be advantageous because of their simpler genetic architecture. The Canadian flax core collection of 390 accessions was genotyped with 464 simple sequence repeat markers, and phenotypic data for nine agronomic traits incl...

BACKGROUND Stink bugs represent a major agricultural pest complex attacking more than 200 wild and cultivated plants, including cotton in the southeastern US. Stink bug feeding on developing cotton bolls will cause boll abortion or lint staining and thus reduced yield and lint value. Current methods for stink bug detection involve manual harvesting and cracking open of a sizable number of immat...

Soil available phosphorus (AP) deficiency and shortage of phosphate rocks limit cotton production in China. Therefore, pool-culture experiments were conducted 2019 2020 using two cultivars (CCRI-79, low-P tolerant; SCRC-28, sensitive) under three soil AP levels (P0: 3 ± 0.5, P1: 6 P2 (control): 15 0.5 mg kg−1) to ascertain the effect on boll biomass lint yield. P0 P1 decreased P concentration n...

The objectives of this experiment were (i) to determine the effect of water supply on the photosynthetic capacity of leaves, bracts, capsule walls, and stalks of cotton at different growth stages and (ii) to determine the contributions of these nonleaf organs to whole plant photosynthesis. Water deficit reduced the total surface area per plant but increased the proportion of nonleaf to total pl...
